Mass 67

When an aircraft is stationary on the ground, its total weight will act vertically

• through its centre of pressure

• through its centre of gravity

• through a point defined as the datum point

• through the main wheels of its undercarriage assembly

During take-off you notice that, for a given elevator input, the aeroplane rotates much more rapidly than expected. This is an indication that

• the centre of gravity may be towards the aft limit.

• the centre of pressure is aft of the centre of gravity

• the centre of gravity is too far forward

• A.  the aeroplane is overloaded.

   

Considering only structural limitations, on long distance flights (at the aeroplane's maximum range), the traffic load is normally limited by

• The maximum zero fuel mass.

• The maximum take-off mass

• The maximum landing mass.

• The maximum zero fuel mass plus the take-off mass

1. At maximum certificated Take-off Mass, an aeroplane departs from an airfield which is not limiting for either take-off or Landing Masses. During initial climb the number one engine suffers a contained disintegration. An emergency is declared and the aeroplane returns to departure airfield for an immediate landing. The most likely result of this

action will be

•      a higher threshold speed and possible undercarriage or other structural failure.

• a higher threshold speed and a shorter stop distance

• a landing further along the runway than normal

• a landing short resulting from the increased angle of approach due to the very high aeroplane mass

At the flight preparation stage, the following parameters in particular are available for determining the mass of the aircraft:1- Dry operating mass; 2- Operating mass. Which statement is correct

• The operating mass is the mass of the aircraft without take-off fuel

• The dry operating mass includes take-off fuel

• The dry operating mass includes fixed equipment needed to carry out a specific flight

• The operating mass includes the traffic load

Which of the following corresponds to zero fuel mass

• Operating mass plus luggage of passengers and cargo

• Operating mass plus passengers and cargo

• The take-off mass of an aeroplane minus all usable fuel

• Take-off mass minus fuel to destination and alternate

On an aeroplane without central fuel tank, the maximum Zero Fuel Mass is related to

•   the bending moment at the wing root

•   variable equipment for the flight.

• wing loaded trip fuel

• Maximum Structural Take-Off Mass

While making mass and balance calculation for a particular aircraft, the term 'Basic Empty Mass' applies to the sum of airframe, engine(s), fixed ballast plus

• all the consumable fuel and oil, but not including any radio or navigation equipment installed by manufacturer

• all the oil, fuel, and hydraulic fluid but not including crew and traffic load

• all the oil and fuel

• unusable fuel and full operating fluids

For the purpose of completing the Mass and Balance documentation, the Dry Operating Mass is defined as

•   The total mass of the aircraft ready for a specific type of operation excluding all usable fuel and traffic load

• The total mass of the aircraft ready for a specific type of operation excluding crew and crew baggage

• The total mass of the aircraft ready for a specific type of operation excluding all traffic load

• The total mass of the aircraft ready for a specific type of operation excluding all usable fuel

Dry Operating Mass is the mass of the aircraft less

• usable fuel and traffic load

• usable fuel, potable water and lavatory chemicals

• traffic load, potable water and lavatory chemicals

• usable fuel
