What is the range of a VOR at 32000ft?
What is the range of a VOR at 32000ft?
Range = 1.23(√H1 + √H2)
= 1.23 * √32000
= 220 nm
What is radiation fog?
What is radiation fog?
Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).
Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.

How do you get out of a spiral dive on a Cessna?
How do you get out of a spiral dive on a Cessna?
-
Unload. Make sure you are no longer 'pulling G's'
-
Roll wings level
-
Power Reduce the power to avoid overspeeding.
-
gently pull back on the control wheel to ease out of the dive.
When slowed down to a safe airspeed apply throttle as needed.
(N.b.: Do not confuse a spiral dive with a spin)
Would you be happy if VMCG is higher than V1?
Would you be happy if VMCG is higher than V1?
No, because if your critical engine fails at V1 you have to continue your takeoff roll, but because you’re under VMCG you are unable to maintain directional control.

Why does a wing stall?
Why does a wing stall?
A wing stalls because the airflow over the wing’s upper surface separates when the critical angle of attack is reached or exceeded. This causes a reduction in the lift generated by the aerofoil
