Weight & Balance Calculations

Next to a good preflight plan and current weather report is a thorough Weight & Balance calculation. This is a matter of serious concern to all pilots as well as many other people involved in the flight.

The pilot has to personally assume the responsibility (and is required by law) because he has control over both the loading and fuel management, the two variable factors which can change both total W/B and the center of gravity.

This information is available to the pilot in the form of aircraft records, operating handbooks and placards in baggage compartments and or fuel caps. The owner of the aircraft has the responsibility to make sure that up to date information is available to the pilot.

The Weight & Balance form we present below can be used for this purpose. It is very important to realize that any aircraft (yes, experimental and ultralight aircraft too) which are out of balance or overweight are dangerous to fly. Not to mention deadly. So please be very, very serious about this.

Aircraft W/B form

This is the one we like to use. It is useful for two and four seat light aircraft. Be careful if weight is in kg and arm is in mm instead of lbs and inches.

Even better: have a look at our E6B APP, it has a weight/mass and balance calculator and much more!


Operating above the maximum weight limitation compromises the structural integrity of the airplane and adversely affects performance and safety of the flight.

Finally: remember to always properly secure any cargo just in case unexpected turbulence is more than comfortable for you or your passengers.
