Chapter 6.5 - Exam Review Flashcards
Define Aeroplane Empty Weight?
The weight of an Aircraft excluding all removable equipment.
Define Gross Weight?
The total weight of an Aircraft at any particular instant.
Define Zero Fuel Weight?
Gross weight of an Aircraft with no fuel.
Define Maximum Takeoff Weight?
The lesser of the Takeoff Weight Structural Limit and Takeoff Weight Performance Limit.
Define Maximum Landing Weight?
The lesser of the Landing Weight Structural Limit and Landing Weight Performance Limit.
Define Specific Gravity?
The ratio of mass for volume of Fuel/Oil to the same volume of Water.
Define Centre of Gravity?
A point where the Aircraft would be balance if suspended at that point.
Define Centre of Gravity Datum?
Loading Reference Point.
True or False. The weight of passengers and the baggage can be determined using statistically averaged ‘standard’ weights?
False for Aircraft’s with less than 7 seats.
What unit is used for calculating the weight of Fuel and Oil?
Kilograms (kg) or Pounds (lb), depending on the units used for the CG envelope.
For an Aircraft to be balanced in equilibrium, what must equal what?
Clockwise Moments equal Anti-Clockwise Moments.
What Moment Indexes are commonly used for Loading light Aircrafts?
100 / 1000 / 10 000 kg-mm or lb-in.
Explain why the position of the Centre of Gravity may move during flight with a constant Loading?
Due to the fuel being burnt during flight.
What are the two critical Loading and Balance checks that a Pilot must make before flying and Aircraft?
Weight and Balance at both takeoff and zero fuel.
What is a Loading Graph/Table?
A graph/table used to calculate the Moments of different Loads.
What is a Load Trim Sheet?
A form/table used to record the loads and moment calculations needed to check takeoff weight and balance at takeoff and zero fuel.
True or False. For an Aircraft to operate in the utility category, the Centre of Gravity and Zero Fuel must both be within the ‘utility envelope’?
True.
What is a ‘Placarded Loading System’?
Loadings rules displayed in the cockpit to check the weight and balance without doing any calculations.
When an Aircraft’s balance is checked prior to flight using a Placarded Loading System, what part of the preflight inspection becomes more important than normal?
To check only the Loads records are on board to start.
Loading a light Aircraft involves checking for a particular flight the load is not exceeding ‘x’? And the ‘x’ is within the ‘envelope’?
- Limiting Weight is not exceeded.
- Centre of Gravity is within the envelope.
