The effect of a VR overspeed on lift off speed and distance and second segment climb gradient is:
Increase increase increase.
The C of G is near its forward envelope limit. Which statement is most correct?
Greater elevator force is required to change the pitch attitude than with an aft C of G position.
An excessively aft C of G when on approach to land will cause?
Light elevator control forces, and decreased pitch stability
A number of swept wing jet transport aircraft have a limitation such that flap extension at high altitudes (typically above FL200) is prohibited. This is because?
The high IAS at such altitude can exceed that of the flap restricting Mach number.
As the speed of a large jet aircraft increases from a stall speed up to cruise speed, the power required to fly straight and level will:
Decrease and then increase.
You are about to descend through cloud containing heavy freezing rain.
The best descent configuration to minimise the risk of airframe ice in these conditions is -
engine RPM up slightly and speedbrakes out
Concerning electrical windshield heating
the window may appear tinted when viewed with reflected light
In comparison to an unswept wing, a swept wing will have a -
lower MAX CL at subsonic and supersonic speeds
A variable incidence tail-plane with stabiliser trim, as an alternative to a conventional elevator with trim -
can produce excessively high control forces if out of trim
The auto pilot depends on devices to measure aircraft attitude changes so that information may be used to achieve controlled flight. Accelerometers assist in a -
set rate of climb and descent
The device that controls the direction of movement of a hydraulic actuating unit, is called the
Selector valve
Assuming the same degree of trailing edge flap deflection, which answer best describes the primary advantage of slotted flaps, compared to fowler flaps ?
Improved boundary layer airflow over flaps.
