The landing distance required will be longer.

Answer

The landing distance will be unaffected.

Answer

The approach path will be steeper and threshold speed higher.

Answer

The approach path will be steeper.

Question 6

If the centre of gravity is near the forward limit the aeroplane will:

Accepted Answer

Require elevator trim which will result in an increase in fuel consumption.

Answer

Benefit from reduced drag due to the decrease in angle of attack.

Answer

Require less power for a given airspeed.

Answer

Tend to over rotate during take-off.

Question 7

An aircraft may be weighed

Accepted Answer

In an enclosed, non-air conditioned, hangar.

Answer

In an area of the airfield set aside for maintenance.

Answer

In a quiet parking area clear of the normal manoeuvring area.

Answer

At a specified 'weighing location' on the airfield.

Question 8

'Standard Mass' as used in the computation of passenger load establish the mass of a child as

Accepted Answer

35 kg irrespective of age provided they occupy a seat.

Answer

35 kg only if they are over 2 years old and occupy a seat.

Answer

35 kg for children over 2 years occupying a seat and 10 kg for infants (less than 2 years) occupying a seat.

Answer

35 kg for children over 2 years occupying a seat and 10 kg for infants (less than 2 years) not occupying a seat.
