Mass and Balance - ATPL - Airline Transport Pilot license

Question 1

If individual masses are used, the mass of an aircraft must be determined prior to initial entry into service and thereafter

Accepted Answer

At intervals of 4 years if no modifications have taken place.

Answer

Only if major modifications have taken place.

Answer

At regular annual intervals.

Answer

At intervals of 9 years.

Question 2

The maximum zero-fuel mass: 1- is a regulatory limitation 2- is calculated for a maximum load factor of +3.5 g 3- is based on the maximum permissible bending moment at the wing root 4- is defined on the assumption that fuel is consumed from the outer wings tank first 5- is defined on the assumption that fuel is consumed from the centre wing tank first The combination of correct statements is:

Accepted Answer

1, 3, 5

Answer

2, 3, 4

Answer

2, 3, 5

Answer

1, 2, 3

Question 3

A load placed aft of the datum:

Accepted Answer

Has a positive arm and therefore generates a positive moment

Answer

Has a negative arm and therefore generates a negative moment and mass

Answer

Has a negative arm and therefore generates a negative moment but a positive mass

Answer

Has a positive arm and therefore generates a positive moment but negative mass

Question 4

Considering only structural limitations, on very short legs with minimum take-off fuel, the Traffic Load is normally limited by:

Accepted Answer

Maximum Zero Fuel Mass.

Answer

Actual Landing Mass.

Answer

Maximum Take-off Mass.

Answer

Maximum Landing Mass.

Question 5

The datum used for balance calculations is:

Accepted Answer

Chosen on the longitudinal axis of the aeroplane, but not necessarily between the nose and the tail of the aircraft

Answer

Chosen on the longitudinal axis of the aeroplane, and necessarily situated between the nose and the tail of the aircraft

Answer

Chosen on the longitudinal axis of the aircraft, and always at the fire-wall level

Answer

Chosen on the longitudinal axis of the aircraft and necessarily situated between the leading edge and trailing edge of the wing

Question 6

The centre of gravity is the

Accepted Answer

Point where all the aircraft mass is considered to be concentrated

Answer

Centre of thrust along the longitudinal axis, in relation to a datum line

Answer

Neutral point along the longitudinal axis, in relation to a datum line

Answer

Focus along the longitudinal axis, in relation to a datum line

Question 7

The actual 'Zero Fuel Mass' is equal to the:

Accepted Answer

Dry Operating Mass plus the traffic load.

Answer

Operating Mass plus all the traffic load.

Answer

Basic Empty Mass plus the fuel loaded.

Answer

Actual Landing Mass plus trip fuel.

Question 8

An aeroplane with a two wheel nose gear and four main wheels rests on the ground with a single nose wheel load of 500 kg and a single main wheel load of 6000 kg. The distance between the nose wheels and the main wheels is 10 m. How far is the centre of gravity in front of the main wheels?

Accepted Answer

40 cm

Answer

41.6 cm

Answer

4 m

Answer

25 cm

Question 9

Loads must be adequately secured in order to:

Accepted Answer

Avoid unplanned centre of gravity (CG) movement and aircraft damage.

Answer

Prevent excessive g-loading during the landing flare.

Answer

Avoid any centre of gravity (CG) movement during flight.

Answer

Allow steep turns.

Question 10

In mass and balance calculations the 'index' is:

Accepted Answer

Is a figure without unit of measurement which represents a moment.

Answer

An imaginary vertical plane or line from which all measurements are taken.

Answer

A location in the aeroplane identified by a number.

Answer

The range of moments the centre of gravity (cg) can have without making the aeroplane unsafe to fly.
