The one engine out take-off distance will become greater than the ASDR.

The VMCG will be lowered to V 1.

The take-off decision speed V1 is:

A chosen limit. If an engine failure is recognized before reaching V1 the take-off must be aborted.

Not less than V2min, the minimum take-off safety speed.

A chosen limit. If an engine failure is recognized after reaching V1 the take-off must be aborted.

Sometimes greater than the rotation speed Vr.

The take-off distance required increases:

Due to downhill slope because of the smaller angle of attack.

Due to head wind because of the drag augmentation.

Due to lower gross mass at take-off.

The take-off performance requirements for transport category aeroplanes are based upon:

Failure of critical engine or all engines operating which ever gives the largest take off distance.

For jet aeroplanes which of the following statements is correct?

When determining the maximum allowable landing mass at destination, 60% of the available distance is taken into account, if the runway is expected to be dry.

In any case runway slope is one of the factors taken into account when determining the required landing field length.

An anti-skid system malfunction has no effect on the required landing field length.

The required landing field length is the distance from 35 ft. to the full stop point.

Which of the following statements is correct?

A stopway means an area beyond the take-off runway, able to support the aeroplane during an aborted take-off.

If a clearway or a stopway is used, the lift-off point must be attainable at least at the end of the permanent runway surface.

An under run is an area beyond the runway end which can be used for an aborted take-off.

A clearway is an area beyond the runway which can be used for an aborted take-off.

Which of the following is true according to JAA regulations for turbo propeller powered aeroplanes not performing a steep approach?

Maximum Landing Distance at the destination aerodrome and at any alternate aerodrome is 0,7 x LDA (Landing Distance Available).

Maximum Take-off Run is 0,5 x runway.

Maximum use of clearway is 1,5 x runway.

Maximum Landing Distance at destination is 0,95 x LDA (Landing Distance Available).

When 'spoilers' are used as speed brakes:

At same angle of attack, CD is increased and CL is decreased.

CLmax of the polar curve is not affected.

They do not affect wheel-braking action during landing.

At same angle of attack, CL remains unaffected.

How does Vmcg change with increasing field elevation and temperature?

Decreases, because the engine thrust decreases.

Increases, because at a lower density a larger IAS is necessary to generate the required rudder force.

Increases, because Vmcg is related to V1 and Vr and those speeds increase if the density decreases.

Decreases, because Vmcg is expressed in IAS and the IAS decreases with TAS constant and decreasing density.

The stall speed increases, when: (all other factors of importance being constant):

Spoilers are selected from OUT to IN.

Minor altitude changes occur e.g. 0-10.000 ft.
