Frequently asked questions
How is the King Air Echo 90 (Beechcraft) 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 King Air Echo 90 (Beechcraft) 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 King Air Echo 90 (Beechcraft)?
The reference maximum takeoff weight of the King Air Echo 90 (Beechcraft) is 10,100 lbs (4,581 kg), per TCDS# 3A20 Revision 82. Always confirm it in your aircraft's POH/AFM.
What are the CG limits of the King Air Echo 90 (Beechcraft)?
The King Air Echo 90 (Beechcraft) CG must be between 144.7" (forward limit) and 160.0" (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 King Air Echo 90 (Beechcraft)?
Yes, as a reference. Every King Air Echo 90 (Beechcraft) 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.
