Fixed Wing Calculations Are More Complex Because Of The Different Failure Modes Resulting In Different Vectors.
These calculations do NOT take into account form drag from the aircraft as it drops. This means the kinetic energy levels being estimated here are conservative and overestimate what we would see in reality.
These calculations assume you do NOT have any forward movement or wind. Forward movement and/or wind will increase the overall amount of KE.
