Flying overgross with CG slightly beyond aft limit
Asked by: Tim Fino 5015 views Aerodynamics
Here is the scenario. I will be flying my Piper Seneca II around the world (refer to: http://www.WingsAroundTheWorld.INFO) and will be installing ferry tanks and getting the necessary FAA approvals for operating at 25% to 28% over gross weight. Because I will be a 'test pilot' on this mission, I fully understand the implications of being over gross weight. The aft limit for the CG in the PA-34 is 94.6 (regardless of the weight). Forward limit is 82. The current design of the ferry tanks indicates that the CG may end up at 96 or 98 - and that is with 150 pounds of fuel in the nose. Is there a legal way that I can emulate or simulate actually flying with the CG at 98? I understand about the control issue and recovery from turbulence. However, the FAA waiver will stipulate 'no turbulence', so the goal is wait when necessary to have smooth air (at least for the first 3-4 hours of the 14 to 16 hour legs). What advice can you offer?
Thank you! Also, let me know if you are interesting in being a co-pilot on the mission!
