Some wings, flaps and rudders are indented, why?
Some wings, flaps and rudders are indented, why?
To increase the strength of the surfaces.
The same strategy is employed by plastic water bottles, by adding ridges to a surface you increase it's structural rigidity
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
Via INS/IRS/GPS
What is anhedral?
What is anhedral?
Downward inclination of a wing from the root to the tip.
How do you prevent an aircraft reaching Mcrit?
How do you prevent an aircraft reaching Mcrit?
Decreasing speed, by reducing engine power or pitching up.
If you have a fire from the engine in the Warrior, what do you do?
If you have a fire from the engine in the Warrior, what do you do?
On the Warrior, I would perform the following items:
throttle closed mixture closed fuel selector off fuel pump off magnetos off (mayday + 7700 if time permits) and check if fire is out heater defrost off batt alt switches off top door latch unlatch seat belts erect secure and make a forced landing
What are the lift qualities of a swept wing?
What are the lift qualities of a swept wing?
Poor, because the sweep-back design has the effect of reducing the lift capabilities of the wing.

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 does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
What does a Mach trimmer do?
What does a Mach trimmer do?
A Mach trimmer automatically compensates for Mach tuck above Mcrit.
Approach category speeds are defined by which formula?
Approach category speeds are defined by which formula?
This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.
The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.
