When climbing at a constant mach number the Calibrated Airspeed (CAS) will
|
Decrease
|
|
When climbing at a constant Mach number the True Airspeed (TAS) will
|
Decrease if the temperature decreases
|
|
The difference between leading edge slats and leading edge flaps is
|
Slats reenergise the boundary layer and plays alter the effective camber of the leading edge
|
|
As an aircraft climbs above FL300, the IAS and EAS stall speeds will
|
IAS and EAS stall speeds both increase
|
|
As an airfract accelerates from subsonic speeds through 1.00m to supersonic speeds, the coefficient of drag will
|
Increase then decrease
|
|
In a constant Mach number climb in the isothermal layer above the tropopause, TAS will
|
Remain constant due to the constant temperature
|
|
In a constant Mach number climb in the isothermal layer above the tropopause, IAS will
|
Decrease due to decreasing pressure
|
|
Mcrit is
|
The speed above which supersonic local airflow first occurs
|
|
The variable most directly affecting the speed of sound is
|
Temperature
|
|
An aircraft exceeds its Mcrit. Assuming no Mach Trimmer is fitted, the first thing that would occur is
|
The nose pitching down
|
|
For high subsonic cruise speeds, the reason it is best to delay the formation of wing shockwaves is
|
To keep the drag penalty to a minimum
|
|
Fast transport aircraft have a supercritical wing section. This is to
|
Reduce the top wing surface acceleration
|
|
Aileron control reversal can be caused by
|
The wing twisting about its lateral axis due to high aerodynamic loads at high speed
|
|
Exceeding Mcrit results in a nose down pitch by the aircraft. This is because
|
The centre of pressure moves rearward
|
|
An aircraft is slowly accelerating through its Mcrit to transonic cruise. The Coefficient of Lift
|
Will increase then decrease
