Aircraft questions Flashcards
what causes stall?
too high angle of attack
different kinds of drag
parasite drag (due to form, skin friction and interference)
induced drag (moving object redirects the airflow coming at it, causes wake vortex turbulence
wake turbulence and approach categories?
L, M, H, J and A-E
A - up to 90
B - 91-120
C - 121-140
D - 141-165
E - 166-211
IAS ALWAYS
kind of wings on Piper28 and DH8A?
Piper=low wing
Dash 8=high wing
what is angle of climb/climb gradient?
altitude gain relative to a distance
describe pitch
controlled by elevators, makes the nose go up and down
4 stages of piston engine:
- intake/induction
- compression
- combustion/power
- exhaust
PFD
primary flight display
altitude, attitude, speed, direction
describe pitot-static system
measures pressure and pressure differences (altimeter, vertical speed indicator, air speed indicator)
describe TAS
changes due to pressure, IAS + 2% per 1000ft, has nothing to do with IAS or CAS
describe V1
takeoff decision speed, if we are at or over V1 we continue, otherwise we won’t be able to stop on the runway
the main concept behind green approach:
to constantly descend
speed or 210kts, headwind 30kts
how long do we fly in 23 minutes?
69
What is angle of attack?
The angle between the chord line of an aerofoil and the relative wind
How is angle of climb “measured”?
