Jet a-1 fsii

A pilot cannot legally fly an aircraft unless: 

1. the aircraft is operated in accordance with the requirements of the Pilot Operating Handbook—including weight and loading limitations;1
2. the load is properly disposed in the aircraft;2
3. the cargo and equipment is secured to prevent shifting and the passenger exits are not blocked.3

There are various terms associated with weight and balance:

• Standard Weight Empty (Standard Empty Weight) is the weight of the airframe and engines with standard equipment, including unusable fuel and oil.

  Essentially, this is the weight of the aircraft when it came out of the factory, before optional equipment was added.

• Basic Empty Weight is the weight of the aeroplane with the current equipment options (instruments, radios, interior features), excluding passengers, cargo and usable fuel; depending on the aircraft manufacturer, basic empty weight sometimes includes full oil weight, and the pilot must examine the aircraft weight
