You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
You are flying at FL350 and the temperature reads -30°C, is the aircraft at its optimum temperature?
No because it is warmer, according to ISA temperature should be -55°C
What pressure does a pitot tube measure?
What pressure does a pitot tube measure?
The total pressure (static and dynamic pressure).
What do the abbreviations TSRA and MIFG mean?
What do the abbreviations TSRA and MIFG mean?
TSRA: Thunderstorm with rain
- MIFG: Shallow fog
What is a jet stream?
What is a jet stream?
Jet streams are narrow bands of high-speed upper thermal winds at very high altitudes.
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
What is Vmu?
What is Vmu?
Vmu is the minimum unstick speed.
It is the calibrated airspeed at and above which the airplane can safely lift off the ground and continue the takeoff. Lift-off is not possible prior to reaching this speed.
Vmu is not an operational speed and is established in flight testing only.
Why is anhedral used instead on some aircraft?
Why is anhedral used instead on some aircraft?
Anhedral:
compensates for the wing sweep improves roll maneuverability
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?
The speed is too low for an indication.

Example answer for a candidate with previous Seneca experience:
Weights:
Max all up weight – take off 4570lbs Max all up weight – landing 4340lbs Empty weight - 2830lbs Usefull load - 1740lbs
Speeds:
Clean stall 66kts with flaps 60kts Vyse 89kts Cruise 140kts gear raising 107kts – lowering 129kts. Vne 195
The 6 cyclinder teledyne continental turbo- charged, fuel injected engines provide 200 hp at 2575.
Left engine rotated clockwise and right anti clockwise.
No critical engine, RayGay turbo’s 42” MAP, 40” limit at lower levels, cowl flaps provide cooling and has 3 positions, open mid and closed.
Avgas 100/130
Props 2 or 3 blade, constant speed, hydraulically actuated, fully feathering.
Oil keeps props at fine pitch, gas and air keep the rpm towards feather. Takes 6 seconds to feather and must happen before locks engage at 800 rpm.
Limit load factor 3.8G
Fuel 2 x 54 (64US) gallons tanks 8 quarts oil max 6 Min
Retractable gear – hydraulic pumps – electrically driven. 6-7 seconds transit
Nose gear has 27 degrees castor.
Main wheels 55psi, nose wheel 31psi
Cable operated controls, all moving stabilator with anti servo tab which acts as a trim.
Frise ailerons and differential ailerons, up more than down.
Manual flaps, 3 settings, 10, 25, 40 degrees.
4.5” – 5.2” hg suction – AH, DI.
Heated lift deflectors and stall warners, anti ice.
What is a high bypass ratio engine?
What is a high bypass ratio engine?
In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.
A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.
