What is windshear?
What is windshear?
Windshear is a change of wind speed and/or direction from place to place, including updraughts and down draughts.
It is ussualy characterized by a strong change over a short distance. Windshear can effect the flight path and airspeed and can be hazardous.

How can you calculate Vref?
How can you calculate Vref?
Vref = 1.3 x Vs0 (stall speed in the landing configuration).
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.

Can a helicopter rotor blade stall?
Yes
Explain what coffin corner is and what happens when reaching the coffin corner?
Explain what coffin corner is and what happens when reaching the coffin corner?
Occurs at absolute ceiling where low speed buffet and high speed (Mach) buffet are coincident.
When reaching the coffin corner, both increasing and decreasing the corner speed will result in a loss of control (either the aircraft stalls, or mach buffeting starts).
