Aerodynamics Flashcards
When is wake turbulence most sever in flight?
Take off and landing due to low speed and high angle of attack.
What is the angle of incidence?
It is the chord angle relative to the longitudinal axis of the plane.
Wing washout creates a greater angle of attack where?
At the root of the wing
What are the advantages of wing washout?
It allows the root of the wing to stall first, giving stability to the wing tips and control of the ailerons.
The most critical aerodynamic factor leading to a stall is?
Angle of attack
The most critical aerodynamic factor leading to a stall is?
Angle of attack
MTOW
Maximum Takeoff Weight
Why is wing icing dangerous?
It disrupts the smooth airflow over the wing, reducing lift and increasing drag.
Induced drag is associated with..
The production of lift
When are wingtip vortices strongest?
When an aircraft is; slow, heavy and clean configuration
What is a consequence of wingtip vertices?
Induced downwash
What are the benefits of a plane with a high aspect ratio wing?
- Better Lift
- Less induced drag
- Improved stability
Lift always acts 90° to?
The relative airflow
What are signs of a stall?
- Angle of attack increases while airspeed decreases
- Controls are less responsive
- Buffeting
Bernoulli’s Principle states…
That the pressure of a fluid decreases as the velocity or height of the fluid increases.
