Load and trim certification

Airline staff working at an Airport with minimum years experience. This is important to ensure that the aircraft will achieve published certified performance and that the aircraft retains expected stability and control characteristics. See full list on skybrary.

Whilst modern automated systems may determine the seating options for passengers and the load disposition, effective procedures and compliance remain the only way of ensuring that what has been specified and passed to the aircraft commander has actually been achieved. Specification of the hold compartment loading is usually achieved by the completion of a Loading Instruction Form (LIF). The LIF is given to the loading supervisor who certifies that it has been complied with and returns it to the issuer as evidence that the work has been completed.

The completed load and trim sheet are then given to the aircraft commander. The human supervisor must also have a reliable means of confirming that if dangerous goods. Many swept wing jet transport aircraft use fuel distribution to optimize the centre of gravity in cruise to reduce fuel burn. The traditional method for ensuring load and trim compliance dates from the days when all load and trim sheets were completed manually on specific forms designed for use with each aircraft type, and is as follows: 1. However, in both cases, the acceptance of an apparently correct load and trim sheet doe.

There are a number of commercial DCS products available. Some are operated by large airlines for their own use and then also employed to generate external user business. Other similar DCS are operated independently of any particular airline. Where DCS are use the data input and electronic generation of the load and trim sheet may be carried out at a regional centre and merely printed off, together with corresponding LIF, by the aircraft operator or the contracted handling agent employees.

Note that DCS will only produce output data as accurate as the inputs, so it is important to guard against input errors. Manual Load sheets involve a pro forma calculation of Maximum Ramp Weight (MRW), Maximum Take Off Weight (MTOW) and Maximum Landing Weight (MLW) whilst the centre of gravity is located by marking the requisite aircraft operating weight (vertical scale) on a ‘drop line’ located on a centre of gravity ‘index’ scale which forms the horizontal axis. If the position so found is within the areas shown as the permitted safe flight envelope, (and remains within the safe area as fuel reduces to planned landing weight) then operation as loaded is possible. Manual preparation of load and trim sheets used to be commonplace but they are now used so infrequently that recalling the necessary method can be challenging to ground staff and flight crew alike. The aircraft commander must be given a copy of the completed load and trim sheet for the flight and should check and sign it, leaving a copy at the point of departure.

The aircraft commander is obliged to accept that the aircraft is loaded as stated in respect of the Loading of Aircraft Holds. It is good practice to complete a. However, in respect of Passenger Cabin Loadingthe senior cabin crew member usually confirms the number of passengers actually on board by means of a headcount after boarding has been completed. For some flights, especially but not only cargo flights, the flight crew have an electronic flight bag (EFB) which they use to calculate aircraft performancedata, which takes account of the completed load and trim sheet. They also use the EFB to make the load and trim calculations themselves, so that once it has been checke all that is required is that a copy be left with the agent at the point of departure.

Clearly, it is vital that a rigorous process of crosschecking is included in the preparation of such documentation to avoid input errors. This can arise in one of three ways: 1. The aircraft is not loaded in the way stated on the accepted load and trim sheet (applicable to any load sheet type) 2. The aircraft load and trim sheet uses correct input data but the output data is wrong (applicable to manual load sheets) 3. The flight crew apply the (correct) load and trim data incorrectly when using it to calculate aircraft take-off performance data, including reference speeds and scheduled thrust settings. The hold load is not properly secured or contains prohibited or incorrectly packed items. What is load and trim sheet?

In other setups, the pitch- trim servo acts in concert with the pitch servo to keep the airplane in trim and to ease the work load of the pitch servo. To certify an autopilot, the manufacturer must prove that a runaway condition will not exceed certain flight loads.
