The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The tailplane of a Seneca has an elevator and a trim tab, what does a Boeing 737 have?
The Boeing 737 has an all moving horizontal stabilizer.
What are the benefits of a free turbine?
What are the benefits of a free turbine?
A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.
Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts
How does GPWS work?
How does GPWS work?
GPWS is a central computer system that receives various data inputs on configuration, (radio altimeter) height/altitude and instrument landing system glide slope deviation and is able to alert the pilot when a dangerous situation is about to occur.
What is the range of a VOR at 32000ft?
What is the range of a VOR at 32000ft?
Range = 1.23(√H1 + √H2)
= 1.23 * √32000
= 220 nm
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.

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.

What’s the temperature at FL150 according to ISA?
What’s the temperature at FL150 according to ISA?
-15°C
because:
-2°C per 1000 feet gives -30°C.
ISA: 15°C at sea level - 30°C = -15°C at FL150
