What is the difference between angle of attack and angle of incidence?
What is the difference between angle of attack and angle of incidence?
Angle of attack is the angle between the chord of the aerofoil and the relative airflow.
Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.
What is RVSM?
What is RVSM?
Reduced Vertical Separation Minima (RVSM) is the reduction, from 2,000 feet to 1,000 feet, of the standard vertical separation required between aircraft flying between flight level 290 (29,000 ft) and flight level 410 (41,000 ft).
Why do aircraft have leading edge devices?
Why do aircraft have leading edge devices?
There are 2 types of leading edge devices:
-Slats. Slats are movable surfaces on the leading edge of the wing which when deployed, allow the wing to operate at a higher angle of attack, by delaying separation in the wing upper surface.
-Leading edge flaps (Krueger). Leading edge flaps are hinged on the leading edge of the wing and extend forward and down when deployed. they provide similar benefits as trailing edge flaps, by increasing wing surface area and camber.
What does the abbreviation MSA mean?
What does the abbreviation MSA mean?
Minimum Safe Altitude.
What uses the most battery power, to transmit or to receive?
What uses the most battery power, to transmit or to receive?
Transmitting uses more power.
What is the range of a VOR?
What is the range of a VOR?
VOR stations are fairly short range: the signals are line of sight between transmitter and receiver and are useful for up to 200 miles.
Each station broadcasts a VHF radio composite signal including the navigation signal, station's identifier and voice, if so equipped.
What do airplanes have to guard against reaching Mcrit?
What do airplanes have to guard against reaching Mcrit?
Barber pole on the ASI, flying at a Mach number at altitude and audible warnings.
What do high lift devices do?
What do high lift devices do?
High lift devices increase the lift produced by a wing, allowing the aircraft to operate at lower speed ranges usually for take off and landing.
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
A high wing location like the BAE and the Fokker give a natural stable contribution.
This is because the Center of Gravity is underneath the wing, therefore when disturbed the C.G. provides a positive momentum opposite to the distortion.
Is carb heat an electrical system?
Is carb heat an electrical system?
No. Carburetor heat uses exhaust air to heat air going into the carburetor. No electrics are involved.
