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
What is a turbo fan?
What is a turbo fan?
A turbofan is a type of jet engine, similar to a turbojet.
It essentially consists of a ducted fan with a smaller diameter turbojet engine mounted behind it that powers the fan.
Part of the airstream from the ducted fan passes through the turbojet where it is burnt to power the fan, but the majority of the flow bypasses it, and produces most of the thrust. They are mainly used commercially because they are highly efficient and relatively quiet in operation.
Why is a great circle the shortest distance between two points?
Why is a great circle the shortest distance between two points?
The track changes constantly.
What clearance do MSA values give?
What clearance do MSA values give?
They provide at least 1000ft clearance over obstacles within 25NM of the homing facility.
What is tire creep, and is it important?
What is tire creep, and is it important?
Tire creep is the tendency of the tire to rotate slowly around the wheel hub as a result of a millisecond landing friction on the tire before wheel spin occurs.
Yes, it is important because if there is too much creep the tire can tear out the inflation valve and cause the tire to burst.
Can a helicopter rotor blade stall?
Can a helicopter rotor blade stall?
Yes
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
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.
What is the coefficient of Lift?
What is the coefficient of Lift?
An adymensional number relating the lift with the dynamic pressure of the incoming flow. It is dependent on the form of the object and the angle of attack.
What is a wing tip?
What is a wing tip?
A wing tip is the part of the wing that is the most distant from the fuselage of a fixed-wing aircraft.
