- when abort speed > Rot speed than ROT = Abort speed
Land as Soon as Possible
emergency declared an da landing accomplished at the nearest suitable landing area considering the severity of the emergency, WX conditions, field facilities, ambient lighting, and command guidance
Land as Soon as Practical
Emergency conditions are less urgent and, although the mission is to be terminated, the degree of the emergency is such that an immediate landing may not be necessary
Suitable Landing Area
- Hard surface runway, taxiway, or under/overrun
- landing on unprepared surface or ditching is not recommended
BATTERY/GENERATOR/STARTER LIMITATIONS? Normal reading?

Time limitations for zero-G and inverted flight. Tolerance?
- Intentional zero-G: 5 seconds
- Inverted Flight: 15 seconds
- Due to gauge tolerance, the a/c may be at zero-g with gauge reading from +.25 to -.25G

- 3. max lateral fuel imbalance 50 lbs
- 4. Max engine operation with only the high pressure fuel pump is 10 hrs
Wind limitations: T/O, Touch and Go, Canopy, Tail wind
- Takeoff (T/O or UP): 25kts
- Touch and Go (T/O or UP): 25knots (20knots)

Checks prior to spins/stalls
CLEFT: "clearing, loose items stowed, Engine check, Fuel Check (balance w/in 50lbs), Trim (elevator set mid-range)
max allowable aircraft in pattern?
what type of patterns can be flown?
at an NTA?
- Max aircraft: 2
- day only, no-formation, winds in limits for rwy of intended use, low approach only, must make all traffic advisory calls and position reports
- Max airspeed: 150kts indicated a/s at or below 2500'AGL within 4 NM of NTA
- Type of pattern: instrument approach, rectangular patterns and ELPs may be flown (left hand traffic). No overhead patterns
how is Max Abort speed/TOR/LRby RCR, GRADIENT (up/down), WIND, Weight, PA, TEMP, Runway Remaining?
How will electrical failure affect landing configuration and TP stalls?
- - no signals to hydraulic selector manifold, therefore nothing will get done
- - Required to use EMERGENCY system (doesn't req electricity)
- - no electricity at all = cannot confirm flap/ldg gear positions
- - normal flap ops is not available when BAT BUS has failed, or AUX BAT is only source of electrical power
how will hydraulic failure affect landing configuration?
- - Ldg Gr doors are electrically sequence and hydraulically actuated
- - lose hydraulic fluid = no be able to move ldg gear and doors
- - EMER hydraulic system must be used to lower gear (gear door do not retract)
how will battery bus failure affect landing configuration and TP stalls?
- -Flaps will still work (powered off hot battery bus only after EMER LDG GR HANDLE is pulled)
- - normal operations not available for flaps and gear
- - landing gear door will not retract (bc must use emergency system)
- motions of the A/C about one or more axis following a stall, but before a spin
- controls ineffective
- near stalled AOA
- erratic A/S indications
- random turn needle deflections
- Spin like motions with unsteady yaw rates
- unsteady movement in all axis
- fully deflected turn needle
- stalled AOA

FUEL PROBE MALFUNCTION
If outer probe fail?
if middle probe fail?
if inner probe fail?
what powers fuel low annunciators?
- Fuel quantity will always show quantity from the most outboard functioning probe so:
- outer probe fails: it will read 445 +- 50# (fuel levels below that will be displayed accurately)
- middle probe fails: will read 308+- 50# (fuel levels below that will be displayed accurately)
- inner probe fails: normal indications until fuel drops to inner probe level, than show half the collector tank quantity of 20#
- * auto balancing is inop
- *fuel low annunciators (<110#) are powered by optical sensors and are separate from fuel probes; so they will indicate correctly when fuel drops below 110# for either wing.
- *do not attempt to manual fuel balance w/ FP fail on AEDD.
