Empty weight and arm differ for every airframe: use the values from your aircraft's weight and balance report (you can add them as a custom aircraft in the calculator).
Frequently asked questions
How is the Diamond DA40 (IO-360, 1150 kg) weight and balance calculated?
Multiply each station's weight by its arm to get its moment, add up weights and moments (including the empty weight) and divide the total moment by the total weight to get the CG. The Diamond DA40 (IO-360, 1150 kg) is within limits when the weight does not exceed the maximum and the weight/CG point lies inside the envelope.
What is the maximum weight of the Diamond DA40 (IO-360, 1150 kg)?
The reference maximum takeoff weight of the Diamond DA40 (IO-360, 1150 kg) is 2,535 lbs (1,150 kg), per TCDS# EASA.IM.A.022 Issue 24 (EASA) / TCCA A-224. Always confirm it in your aircraft's POH/AFM.
What are the CG limits of the Diamond DA40 (IO-360, 1150 kg)?
The Diamond DA40 (IO-360, 1150 kg) CG must be between 94.5" (forward limit) and 102.0" (aft limit) aft of datum. The effective limit depends on weight: the envelope on this page shows its full shape.
Can I use this calculator for my Diamond DA40 (IO-360, 1150 kg)?
Yes, as a reference. Every Diamond DA40 (IO-360, 1150 kg) has its own empty weight and arm depending on its equipment: enter them from its weight and balance report as a custom aircraft. The POH/AFM is always the official reference.
