Weight & Balance and Load Planning – 5 Days


Both Weight and Balance are essential to the well being for an aircraft to experience safe flight. The Root Cause of Multiple Aircraft Incidents can be attributed to overloaded aircraft or where they have been incorrectly balanced in their distribution of weight.

There are various factors involved in weight and balance accidents/incidents such as errors in the load sheet, shifting of cargo, incorrect loading. (The risk of having a weight and balance related accident with cargo flights is 8.5 times higher than with passenger flights.)

Weight & Balance should also consider the Loading & Burning of Fuel, Loading & Unloading of Baggage’s and Boarding & Deboarding of all Passenger’s in Commercial Planes as well as Loading & Unloading of External Stores in Military Planes at any time during the preparation, loading, operation, disembarkation and unloading of the aircraft.

This course is focused on the need to ensure, that at all times safe loading as well as weight & balance are ensured to maintain Safety of the Flight at all times and in particular during Take-off & Landing.

Who is the course for?

It is for Regulatory Authorities and persons who are involved in the Technical Engineering Management , Design Engineering Team, Pilots, Marketing Team, Procurement Team, Manufacturing/Tooling Team, Technical Publications, Flight Operations, Customers.
