Flight Load Factors for Flaps Full.

Asked by: 941 views Aerodynamics, Aircraft Systems, Commercial Pilot, General Aviation, Light Sport Aircraft, Private Pilot, Student Pilot

When I look up on operating limitations chapter of POH, Cessna published load factor limits for Flaps UP and FULL.

For Flaps UP, there are positive and negative ones, but for Flaps FULL, only positive load factor is published.

Does anyone have seen this before?

    I have seen it in the Cessna POH, in a Piper Arrow POH no negative G rating is published and instead it says “No inverted flight permitted.” In the Cap 10 (aerobatic trainer) it publishes both flaps up and flaps down positive and negative. I’d guess they either didn’t test it or are not listing it because it might lead the dare devil pilot to try inverted flight in an aircraft that is obviously not meant to fly upside down.

    is that because negative G value is smaller than that of positive G?

    It is airplane dependent. I have not read much on how flaps effect load distribution or structural integrity. I suspect that has to do with there not being much need for that analysis.
