In the preceding examples the reference datum was the centre of gravity of the unladen seesaw, which was coincident with the fulcrum. How much freight must be added to a hold 10ft forward of Datum to move the CG 1ft forward.

031 Aircraft Mass & balance (JAA ATPL theory).

A mechanical device inserted between the cargo and the aircraft floor to distribute the weight evenly over a greater floor area. The graphs shall be identified by aircraft designation, date of compilation and source.

Tempest Tempest – Aero. Sector Distance 1, nm. CG envelope from 1 inch to 4 inches forward of the datum at all weights.

The Total Weight of the aeroplane then comprises of the APS weight plus balancs Disposable Load, which is made up of the usable fuel and traffic load.

As already discussed, the disposable load consists of the usable fuel and the traffic load. The following examples illustrate the method of calculating the weight and arm of empty aircraft with various datum positions.

Seat 7 0 lb. Add the weight and moment of the ,ass expected to remain in the tanks at the end of the flight. The maximum traffic load that may be carried in any circumstances.

The fuel slide is indexed in Imperial gallons. He must establish a system to check that amendments of his tapl data are incorporated properly in the system and that the system is operating correctly on a continuous basis by verifying the output data at intervals not exceeding six months. The Joint Aviation Authority has the maa of ensuring that all public transport aircraft, irrespective of size or number of engines, are operated to the highest possible level of safety.


It would be prudent to re-weigh the aircraft if it is uaa attaining is scheduled performance level. The following examples illustrate how to convert the position of a CG which is given as a percentage of the MAC into a position which qtpl relative to the reference datum, and the reverse. Specify the current restraint load factor forward for lashing and tie-down equipment for fixed wing aircraft.

Determine the change in the position of the CG if 1, kg of load is moved from a hold 12 metres aft of the datum to another 5 metres aft of the datum. When loading the aeroplane care must be taken not to exceed the maximum weight permitted in specific baggage areas.

As and when you are introduced to new aircraft types, both during your flight training and during your subsequent career, you will be taught the loading procedures which are specific to that particular aircraft type. Add the take-off fuel Box 37 to the zero fuel weight to obtain the take-off weight Box Its purpose is to extend the load intensity over a larger floor area than the base of the item and at the same time protect the aircraft floor from damage.

Basic weight 50, kgs; Basic equipment 5, kgs; Usable oil kgs; Variable load kgs; Traffic load kgs; Usable fuel kgs. The weight and moment of the crew is included in Part B. In this example the total passenger weight is 23, lb. Dividing the total moment by is simply a device which is used in order to keep the numbers to a manageable magnitude.


Aircraft Mass & balance (JAA ATPL theory).

List the factors that may limit the take-off weight. Insert at 3 and Aviation Press Aviation Specia. If the centre tank balaance the MRJT contains kgs of fuel how much fuel must be in the wing tanks? So far all of the calculations concerning the position of the CG of an aircraft have considered the position along the fore and aft axis. Standard weights are assumed for this exercise. The position of the CG measured along the fore and aft axis of the aircraft will change due to changes in aircraft configuration passenger configuration with seats in, freight configuration with seats outtotal weight and distribution of the fuel load at any given point in the flight, total weight and distribution of the payload, and so on.

Cessna Champion Champion Aerosp. Role equipment is that which is required to complete a specific task such as seats, toilets, galley for the passenger role or roller conveyor, lashing points and tie down equipment for the freight roles. They are further classified as male or female. Maximum Ba,ance Weight at B 37, kg. The effects of operating with the centre of gravity aft of the permitted aft limit include: Wicom Znd Windcone Sales.

In this case at any specified distance from the fulcrum, the turning moment that is the downward force imposed at that point will be equal on both sides of the fulcrum.

The total weight of the aeroplane comprises the APS weight plus the disposable load, which is made up of usable fuel and the payload.
