3000 ± 120 psi
What is the minimum normal hydraulic pressure to operate components?
What function does the check valve have?
Prevents emergency system from bleeding into the main system
What function does the hydraulic fuse have?
Prevents emergency system from bleeding into the main system; 20-30 cubic inches (0.5 quarts) to leak at a rate of 0.25 GPM
How much do the flaps extend for flaps TO and LDG?

How much do the ailerons move?
20° up; 11° down; ±6° trim
How much can the elevators move?
18° up; 16° down; 5.5° up trim; 22° down trim

Under what situations should engine start be aborted?
ITT rate of increase appears likely to exceed 1000° C; Normal N1 increase is halted; No rise of ITT is evident within 10 seconds after fuel flow indications (no start); BAT BUS annunciator illuminates during the start sequence; PCL is moved or the ST READY annunciator extinguishes during the start sequence
What are indications of engine fire on the ground?
Primary are FIRE and MASTER WARN annunciators;
Under what conditions should the engine be shutdown on the ground?
Engine Fire; Prop strike; Chip Light; Departing a prepared surface; Any other serious ground emergency
What are indications of a complete engine failure immediately after takeoff?
A total loss of power and a fairly rapid reduction in airspeed.
What are initial indications of engine failure/flameout?
Low of power and airspeed; Rapid decay of N1, torque, and ITT; Propeller movement towards feather due to loss of oil pressure
At what percent does Torque being to indicate?
What annunciators will illuminate after an engine failure?
Initially, GEN, FUEL PX, OIL PX; Followed by OBOGS FAI
What should the initial reaction to any engine malfunction at low altitude be?
Trade Airspeed for altitude; Zoom if above 150 KIAS, maintain level glide if below 150 KIAS
What kind of pull should be initiated if above 150 KIAS and the engine fails?
2G pull up to a 20° climb. Use 20 KIAS lead to initiate a 0 to +0.4 G pushover to capture glide airspeed
How much altitude gain can be expected from 200 KIAS? 250 KIAS?
200 KIAS: 600 to 900 ft ; 250 KIAS: 1170 to 1550 ft
How much altitude loss can be expected with each airstart attempt?
1200 ft total, 1350 to 1500 ft/min
How long will it take before useful thrust can be developed after an airstart attempt?
How long will it take before the propeller RPM unfeathers and accelerates to normal operating RPM?
Simultaneous illumination of PMU FAIL and PMU STATUS; Step change in engine power
How long will it take to drain the battery if starter is left in MANUAL?
How long will the generator and battery buses be powered?
Until 16 volts
When are flaps LDG landings performed?
When landing distances are >=80% of runway length
When are flaps TO landings performed?
For full-stop landings with 10 knot or greater crosswind
When are flaps UP landings performed?
Full-stop landings with >20 knot crosswinds if landing distance is not a factor
When should a breakout from inside downwind be performed?
Aircraft in final turn and not in sight; Straight in inside 2 miles and not in sight; ELP inside low key and normal spacing cannot be maintained; Pattern spacing cannot be maintained within normal ground track; Not properly configured by the perch point
How should approach speeds be changed with high weight?
Above 700-800 lbs of fuel, approximately 3-5 knots above final turn and final airspeed.
What is the airspeed to altitude relationship?
10 knots airspeed can be traded for 100 feet of increased altitude
How much altitude can be lost in a 360° turn?
30° bank – 2,000 ft; 45° bank – 1,500 ft; 60° bank – 1,000 ft
What is the expected glide ratio for a clean, feathered aircraft?
2 miles per 1,000 ft (2:1) with 1,350 – 1,500 fpm descent rate
