07 Flight Ground Limitations

The maximum allowable airspeed with flaps extended (V_FE) is lower than cruising speed because:

• Flaps are used only when preparing to land.

• Too much drag is induced.

• Flaps will stall if they are deployed at too high an airspeed.

• At speeds higher than V_FE, the aerodynamic forces would overload the flap and wing structures.

In a climb at a steady speed, the thrust is:

• Equal to the aerodynamic drag.

• Less than the aerodynamic drag.

• Greater than the aerodynamic drag.

• Equal to the weight component along the flight path.

What is the significance of the speed known as Vno?

• It is the maximum speed at which abrupt movements of the controls will result in a stall, before the aircraft's positive load limit is exceeded.

• It is the speed beyond which structural failure of the airframe will occur.

• It signifies the upper limit of the normal operating speed range.

• It signifies the airspeed which must never be exceeded.

If an aircraft is flown at its design manoeuvring speed Va:

• It is possible to subject the aircraft to a load greater than its limit load during high ‘g’ manoeuvres.

• It is not possible to exceed the limit load.

• It is only possible to subject the aircraft to a load greater than its limit load during violent increases in incidence, i.e. when using excessive stick force to pull-out of a dive.

• It must be immediately slowed down if turbulence is encountered.

The maximum angle of climb of an aeroplane is determined by:

• Excess engine thrust.

• The aircraft weight.

• Wind speed.

• Excess airspeed.

V_NE is:

• The airspeed which must not be exceeded except in a dive.

• The maximum airspeed at which manoeuvres approaching the stall may be carried out.

• The maximum airspeed at which the aircraft may be flown.

• The maximum speed, above which flaps should not be extended.

The angle of climb is proportional to:

• The amount by which the lift exceeds the weight.

• The amount by which the thrust exceeds the drag.

• The amount by which the thrust exceeds the weight.

• The angle of attack of the wing.

When an aircraft is in a steady climb, the aerodynamic lift is ______ the weight.

• Balanced by.

• Equal to.

• Less than.

• Greater than.
