Aircraft Mass and Balance - Terminology

The Operating Mass is

• dry operating mass plus the take-off fuel mass

• empty mass plus the trip fuel mass

• empty mass plus the take-off fuel mass

• empty mass plus the operating items

Which statement is correct?

• The DOM includes fixed equipment needed to carry out a specific flight

• The OM includes the traffic load

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

• The DOM includes take-off fuel

The traffic load is considered to be equal to the take-off mass

• plus the trip fuel mass

• minus the trip fuel mass

• minus the operating mass

• plus the operating mass

What is the correct definition of traffic load?

• The total mass of flight crew, passengers, baggage, cargo and usable fuel

• The total mass of flight crew, passengers, baggage and cargo including any non-revenue load

• The total mass of crew and passengers excluding any baggage or cargo

• The total mass of passengers, baggage, cargo and usable fuel

Basic empty mass can be defined as the sum of the:

• basic mass + variable equipment mass

• standard empty mass + specific equipment mass + trapped fluids + unusable fuel mass

• basic mass + variable equipment mass

• dry empty mass + variable equipment mass

The useful load is

• TOM - fuel mass

• BEM + fuel load

• TOM - DOM

• TOM - OM

The zero fuel mass and the dry operating mass

• differ by the value of the traffic load mass

• are the same value

• differ by the sum of the mass of usable fuel pus traffic load mass

• differ by the mass of usable fuel

The dry operating mass is the total mass of the aircraft ready for a specific type of operation but excluding

• potable water and lavatory chemicals

• usable fuel, potable water and lavatory chemicals

• usable fuel and crew

• usable fuel and traffic load

The actual zero fuel mass is equal to the

• dry operating mass + traffic load

• basic empty mass + fuel loaded

• operating mass + traffic load

• actual landing mass + trip fuel

Crew baggage is considered to be:

• bulk load

• palletized load

• variable load

• containerized cargo load
