According to easyJet, how much will the fuel efficiency increase with the new coating?
up to 2%
What are the 2 different types of drag?
Parasite and Induced drag
Describe Induced drag.
Induced drag is the result of lift. Wingtip vortices modify up wash and downwash in the vicinity of the wing which produces a rearward component to the lift vector known as induced drag. The lower the IAS, the higher the AOA � the stronger the vortices, the greater the induced drag. Factors that affect induced drag are; the size of the lift force, the speed of the aircraft, the aspect ratio of the wing.
Describe Parasite drag.
Parasite drag is independent of lift generation and is subdivided into: Skin friction drag, Form (pressure) drag, Interference drag. Parasite drag varies directly with the square of the IAS. Factors affecting parasite drag are: IAS, Configuration and Airframe contamination. Parasite drag varies directly in proportion to the frontal area presented to the airflow (flaps, gear etc..). Contamination by ice, snow, mud or slush will increase the parasite drag coefficient.
Why do modern jet aircraft have such large all moving horizontal tail planes?
- - To provide a balancing force for large CG ranges (due to fuel consumption)
- - To provide a balancing force for a large speed range
- - To minimise the drag, since the aerofoil is more streamlined
- - To cope with large trim changes as a result of position changes to the wing leading and trailing edge high lift devices.
- - Trimming does not reduce the range of pitch control, as the elevator is approximately neutral when the aircraft is trimmed.
Why are swept wings used?
To increase Mcrit.
How does wing sweep help speed and C of G ranges?
Mcrit depends on the airspeed vector perpendicular tot he leading edge. Because sweep shortens this vector, the airspeed can be raised before reaching Mcrit.
What are the advantages and disadvantages of swept back wings?
- High Mach cruise speeds
- Stability in turbulence
- Poor lift qualities
- Higher stall speeds
- Speed instability below Vmd
- A wingtip stalling tendency
What are the aerodynamic consequences of having under-wing mounted engines?
A pitch up moment when adding thrust, delaying wing flutter to a higher speed, Pylons can acts as fences to minimise spanwise flow at high angles of attack.
How does having underwing mounted engines effect the airflow over the wing?
At high angles of attack the airflow over the wing, influenced by pod mounted engines, can acts as a fence, thereby reducing spanwise flow.
What are slats/ slots and Why are they used?
A slat is a auxiliary aerofoil attached to the leading edge of the wing. Leading edge slats increase the wing�s chamber area and Mean Aerodynamic Chord (MAC), thereby increasing it�s lift coefficient and reduce the stall speed. When deployed, the slat forms a slot which allows the passage of air from the high pressure region below the wing to the low pressure region above. Additional kinetic energy is added to the airflow. It reenergizes the boundary layer and thereby delaying boundary layer separation to a much higher AOA.
What is Dutch Roll and how is it caused?
Dutch roll is an oscillatory instability associated with swept wing jets. It is a combination of yawing and rolling. When a yaw is induced the strong dihedral effect will role the aircraft due to the lift increase on the wing into wind. The increased induced drag on the rising wing will yaw the aircraft in the opposite direction, reversing the coupled oscillation.
What are the functions of a yaw damper?
The yaw damper is a device to counter Dutch Roll and coordinate turns. This automatically displaces the rudder proportional to the rate of yaw to damp out the oscillations.
What is Vmca?
Vmca is the CAS, at which, directional control can be maintained in the air with the critical engine inoperative, with a maximum angle of bank of not more than 5 degrees.
What is Cmcg?
Vmcg is the CAS during the rake off run at which it is possible to maintain directional control on the ground, in the event of a failure of the critical engine, without the use of nose wheel steering (primary aerodynamic controls alone) to enable the take off to be safely continued using normal piloting skills.
What is Mcrit, and why is it a problem flying faster?
- Mcrit is the free stream mach number at which the local velocity first reaches Mach 1 (sonic). (Usually the point with thickest chamber).
- At speeds, faster than Mcrit:
- - Increase in drag (because of airflow separation)
- - Initial Mach buffer (caused by the shock waves on the upper surface of the wing)
- - A nose down change in attitude (mach tuck)
What is mach tuck, why and how do we prevent from happening?
- Mach tuck is the nose down pitching moment an aircraft experiences as it passes its critical Mach number (Mcrit). It is cause by the rearward movement of the center of pressure.
- Mach tuck is prevented by a Mach trimmer. This is a device that corrects for Mach tuck by sensing the aircraft�s speed and signalling a proportional upward movement of the elevator or variable incidence stabilizer to maintain the aircraft�s pitch attitude.
What is a vortex generator?
A vortex generator is a small aerofoil which creates a vortex at its tip. This induces high energy air from the free stream flow to mix with the boundary layer.
Why are Vortex generators used?
They are used to prevent span wise flow (delay flow separation), and to maximize effectiveness of control surfaces (such as ailerons)
Other than a wing where else might Vortex generators be used?
Other than the wing they might be used on the engines to redirect the airflow on the downside of the wing (wing mounted engines) and APU inlet.
Why would you have vortex generators in front of an APU inlet?
Because the inlet requires high density air and of a slower velocity. Vortex generators disturb the airflow, generating a denser and of a slower velocity airflow.
What happens if you move the throttle?
Pitch up moment, because the thrust line is below the CG
Difference between flap 30 and flap 40
Flaps 40 will decrease the approach speed, and thereby decrease the landing run. Also better visibility because of lower attitude.
Why would we have bleed valves on the engine?
- 1. To provide bleed air for auxiliary systems
- 2. To regulate the correct airflow pressures between different engine sections.
When does a cross bleed air start happen?
During inflight restarting of an engine and on the ground when APU is not available. Extra precautions must be taken care of with a crossbleed air start on the ground, because the required rpm on the running engine must be higher than idle.
List the uses of bleed air
- � Pressurisation
- � Air conditioning
- � Engine and airframe anti icing
- � Engine start
Explain how bleed air is used in the water system in the toilets of a modern jet?
Bleed air is used to supply pressurized air to the potable water system. The pressurized air moves the potable water tank to the galleys and lavatories. The pressure for the potable water system is between 25psi and 28psi.
How does a Jet engine work?
By forcing incoming/ take in air into a tube, where the air is compressed, mixed with fuel, burned and exhausted at high speed to generate thrust.
What is the difference between a turbofans and turbojet engine?
Most components remain the same in a turbofan and turbojet engine, but the turbofan engine introduces a fan section in front of the compressors. This fan is also turbine driven but it�s primary purpose is to force a large volume of air through outer ducts that go around the engine core. This large mass of air that is accelerated by the fan produces a significant thrust without burning any additional fuel.
What is the difference between a gas turbine and a jet engine?
A jet engine is an engine which has no rotating parts, but works on ram air. It is therefore not suitable for aircraft since it cannot generate thrust at low speeds. A gas turbine engine incorporates compressors, driven by turbines.
How are the turbine blades cooled?
- By 3 ways:
- 1. Convection cooling; by passing cooling air through passages internal to the blade
- 2. Film cooling; by pumping cool air out of the blade through small holes. The air creates a thin layer on the blade of cool air protecting it to the high temperatures.
- 3. Transpiration cooling; It creates a thin film of cooling air on the blade by leaking through a porous shell

by passing cooling air through passages internal to the blade.
How does film cooling work?
by pumping cool air out of the blade through small holes. The air creates a thin layer on the blade of cool air protecting it to the high temperatures.

Why pressurise the hydraulic system?
To prevent pump cavitation
What kind of engine does a Seneca have?
A six cylinder, horizontally opposed, direct driven, Fuel injected, Air cooled, turbocharged, wet sump oil system, 200 Rated HP
What differences do we have when mounting engines under the wing instead of at the aft fuselage?
- - Intake efficiency is rarely compromised by interference flows
- - The engines provide bending relief, thus reducing wing structure weight
- - At high incidence the pylons tend to act in a way similar to fences by controlling span wise flow
- - Good engine accessibility
- - Unless the engines are mounted well inboard the asymmetric yawing moment following failure is high, so this demands good rudder control
- - Roll freedom on the ground is limited.
- - A low thrust line can have an adverse effect on longitudinal control
- - Low mounted engines encourage ingestion from the runway surface. (FOD damage)
What de-ice/ anti-ice equipment does the Seneca have?

What de-ice/ anti-ice equipment does the A320 have?
- The ice and rain protection system lets the aircraft operate normally in ice conditions or heavy rain. Ice protection is given by the use of hot air, or electrical power, to make the necessary areas of the aircraft hot.
- The areas that hot air supplies are:
- - The leading edge of the slats 3,4 and 5 on each wing
- - The engine air intakes
- The engine bleed air system supplies the hot air to the anti-ice system.
- The items with electrical heaters are:
- - Cockpit windshield and side windows
- - The Total Air Temperature (TAT) probe
- - Angle of attack probes

How long does it take for an IRS to align in the A320?
What sort of flaps does the airbus have?
- Fowlerflaps (it moves rearward and then down)
- It increases the wing area and then the camber and may be slotted. The change in pitch moment is usually greater because of the rearward extension of the chord.

If you don�t have enough track miles, how do you solve that problem?
request delaying track miles, request the amount of track miles needed, use speed brake in the descent, add additional drag (use gear or flaps).
Why would we circle to land, why not just fly straight in?
To bring the aircraft into position for landing on a runway not suitably located for a straight in approach.
Describe the four climb segments.
- 1st: Begins at 35� over the runway (screen height) to the point where the gear is fully retracted. Positive climb gradient
- 2nd: Begins at gear up and terminates at minimum flap retraction altitude. Climb gradient 2,4% (could be at 400� depending on procedures)
- 3rd : Starts at flap retraction and ends with flaps retracted. Climb gradient: 1,2%
- 4th : Starts with enroute configuration reached, ends at 1500 ft over runway elevation. Climb gradient 1,2%
What are the stages of a thunderstorm?
- 1. Developing stage; Updrafts move air aloft, allowing condensation to take place throughout the ascent of the convective currents
- 2. Mature stage; The most hazardous stage of a thunderstorm. The dangers include; torrential rain, hail, severe turbulence, severe icing, winds hear, microburst�s, lightning. Downdraughts and up draughts.
- 3. Decaying stage; The final stage of a TS. Still winds hear danger.
How can you tell a thunderstorm is in its dissipating stage?
No more continuous rain, but sporadic showers, sometimes as virga due to a temperature inversion beneath the cloud base, which can cause a marked windshear.
What is the Dew Point?
Dew point is the temperature at which a parcel of air becomes saturated. It�s capacity to hold water vapour is equal to that which it is actually holding. It�s relative humidity is 100%.
What is virga?
Virga is rain that falls from the base of a cloud and evaporates at a lower altitude in drier warmer air before it reaches the ground. This is a sign of a temperature inversion, which in turn is an indication of possible windshear.
What is a microburst?
a severe concentrated downdraft, or a vertical wind, emanating from the base of a mature CB, with high speeds and a lower temperature than the surrounding air.
From TAF/METAR BR, GR and FU
- BR = mist
- GR = Hail
- FU = Fumes
Tell me about adiabatic lapse rates, what are they? What are the assumed values?
- SALR DALR ELR
- ELR is the rate of temperature change with height of the surrounding atmosphere. The ISA assumes an ELR of 2C per 1000ft of height/ altitude gained. The actual ELR may differ greatly from this; in fact it can be zero (isothermal layer) or negative (inversion).
- DALR is the adiabatic temperature change for unsaturated air as it rises. Unsaturated air is known as dry air and it�s change in temperature is a rather regular drop of 3C per 1000ft height/ altitude gained.
- SALR is the adiabatic change in temperature for saturated air, as it rises. The SALR commences at a height where a parcel of air�s temperature is reduced to its dew point temperature, 100% relative humidity, and its water starts to condense out to form cloud. Above this height, the now saturated air will continue to cool as it rises, but because it releases latent heat as the water vapour condenses to a liquid form, i.e. clouds, its cooling rate is reduced to a rather regular drop of 1,5C per 1000ft height/ altitude gained.
What is the Foehn wind?
- The fohn wind is a dry down-slope wind that occurs on the lee side (downwind) of a mountain range. It can be seen in the Alps.
- Air is cooled as it is forced to rise over high ground, first at the DALR and then, after the dewpoint level is reached, at the SALR. After the dewpoint clouds will be formed and moisture will be lost, in the form rain or dew.
- As the air descend over the far side of the hill, it has a lower water content and so the dewpoint level is higher. A longer period of warming at the DALR means that the air on the far (downwind) side of the hills is warmer and dryer than it was on the upwind side of the hill.
- The fohn effect can influence the wind direction and strength and in some cases even generate a wind that blows down the far/lee side of the hill.
What would you do if you flew into unexpected weather?
Make sure the aircraft is under control, check for icing conditions, check for turbulence (wx radar), and if needed turn 180 degrees, check up to date information with ATC.
What does CAVOK mean?
- 1. Visibility equal or greater than 10km
- 2. No clouds below 5000� or below the highest MSA, whichever is the greater, and no CB

When would you go around during an approach?
MDA/ DA/ Half scale deflection/ Unstable at 1000�/ not properly configured/ checklist not done
Obviously fuel is a huge cost to an airline, how would you help use less fuel?
- 1. Take only the fuel needed
- 2. Fly as much as possible at the optimum altitude
- 3. Request for shortcuts/ shorter routing
- 4. Careful planning
- 5. Not too early/ not too late start configuration (flaps, gear etc..)
- 6. Minimize the use of APU
- 7. Continuous descent approaches
- 8. Taxi on one engine
You fly at FL300, where is your TOD when you approach Gatwick?
What is the airspeed and what is the approach speed? Alt/1000 x 3 + 1 mile every 10 kts.
What is the effect of weight on your descent?
Weight does not affect the glide angle because it is lift/ drag ratio that determines the glide angle, provided that the correct airspeed is flown. The only effect weight has is the time it takes to descent. So the heavier the weight, the higher the gliding airspeed, the faster the descent. So if two aircraft with the same L/D ratio, one heavier than the other are to start the descent on the same point, the heavier aircraft will reach it�s destination sooner than the lighter, but cover the same distance.
Engine fire drill and who do you inform
(wanted to hear cabin crew after ATC) (boeing SOP is fine) AVIATE, NAVIGATE, COMMUNICATE!
You are on your way from Malaga to Gatwick; cpt not responding and not feeling well; what do you do?
Switch on the autopilot if not switched on yet, to reduce workload, make sure the flightpath is under control, get a cabin crew member to strap the captain in his chair, so not to influence the flight controls, make a panpan medical call, check if a doctor is onboard, get the latest weather for any airfields in the vicinity and check for familiar airports, inform the cabin and company, divert

- - Work too much
What do you feel about working unsociable hours?
I am totally fine with that and actually enjoy working variable hours. I am currently working for KLM�s department of line maintenance and we are working in three shifts. I enjoy the evening and nightshifts because it gives you plenty of time to do some work at home and the day shifts start early, but end early as well, which gives you enough time to socialize.
What makes you a good first officer?
I am a social, punctual and enthusiastic person who always tries to create a good atmosphere in a team and create a common goal.
Why did you choose OAA/ EPST? Did you look at any other schools?
I did look at other schools, but after careful consideration and advice from other pilots and students, I chose for EPST and OAA. This was mainly because of the good reputation of both schools, the good job placement records and the training abroad. This gave me the opportunity to fully concentrate on my training without the distractions of friends, family and my girlfriend. It also gave me the opportunity to improve my English.

How can Vmcg/a be changed?
By change of CofG and reduced thrust.
Explain how Vmcg/a is reduced by change of Center of Gravity.
- By changing the C of G. The turning moment acts around the center of gravity. A forward center CofG will have a longer arm, and therefore, the vertical tailplane turning moment is greater for a given speed, and thus the aircraft can have a lower Vmcg/a.
- Turning moment = rudder to center of gravity arm x speed (Vmcg/a)
- So; CofG aft = higher Vmcg/a and CofG fwd lower Vmca/g
Explain how Vmcg is changed by reduced thrust.
With reduced take of thrust (only Vmcg!). The rudder turning moment is used to oppose/ balance the assymetrical thrust yawing moment to maintain directional control. Therefore, by reducing thrust, any off center engine loss during the takeoff run has a reduced assymetrical thrust imbalance, which thereby reduces the yawing moment to maintain directional control. Because the magnitude of the tailplane turning moment is a product of airspeed, a lower (Vmcg) groundspeed maintains the aircraft�s directional control.
Why are the turbine blades shrouded?
To minimise losses due to leakage across the turbine blade tips and reduce vibration.

Background on me and why I want to be a pilot
Aangestoken door neef, muziek industrie in gewerkt, toch piloot willen worden.
Why do you want to be a pilot?
I want to be a pilot for a couple of reasons; the view, it�s a perfect mix between technical, commercial and social aspects, seeing the world, travelling.
Why do you like flying?
I like to see the world passing by underneath you, I like the mix that flying brings between technical knowledge, commercial aspects and social aspects. It�s a great feeling to be very busy with flying the aircraft, checking weather, checking fuel status, making decisions, listening and talking to ATC, and be able to land the aircraft safely on the arrival aerodrome.
Why do you want to work for easyJet?

Describe a time when you have had to make an instant decision and it was the wrong decision.
Give me an example of when you were in a team and you had to motivate the fellow team members and step up to the lead.
SilvaScreen eerste jaar crisis.
What do you think of the flexi crew contract?
It would have my preference not having to pay for the type training, but it is the reality today that most airlines are using these kind of programs to lower their training expenses. It also enables the company to filter out people who aren�t really motivated and dedicated to join the company. easyJet and it�s values and company policy really appeals to me, so if I did have to sponsor my own type training I wouldrather do that for easyJet than any other company.
Why does a swept back wing stall at the wing tip first?
This is due to the induced spanwise flow of the boundary layer from root to tip.
Which design features can be incorporated to reduce the wing tip stalling tendency?
Wing fences, Vortilons, saw tooth, vortex generators , pod mounted engines
What happens to the CP with a wing tip stall?
The CP moves forward giving a nose up pitching moment.
What does a vortex generator do?
They generate a small vortex which causes the free stream flow of high energy air to mix with and add kinetic energy to the boundary layer. This re-energises the boundary layer and tends to delay seperation.
What could be visual clues of windshear?
- - Virga
- - Rising dust or sand
- - Divergent wind sleeves or smoke
- - Divergent wind patterns indicated by grass, crops or trees

What is a fly-by-wire system?
A FBW system is a system that replaces the conventional manual flight controls of an aircraft with an electronic interface.
Explain a fly by wire system?
When the pilot moves the control colum or side stick, a signal is sent to an computer. this signal is sent through multiple channels (wires) to ensure that the signal reaches the computer. The computer receives the signals and performs a calculation and adds another channel. These signals are sent to the control surface actuator and the surface begins to move. Potentiometers send a signal back to the computer reporting the position of the actuator. When the actuator reaches the desired position, the two signals (incoming and outgoing cancel each other out and the actuator stops moving.
