I do not understand. Negative Gs are the result of changing the direction of the plane's nose in a downward direction at a pace that exceeds 32 ft/sec squared. That is why one can encounter negative Gs with an abrupt leveling off at the end of a climb. >Positive Gs are tested with the wing inverted, simulating the increased >lifting force beyond 1G that is created when one increases the load on the >wing during say a steep turn, pull-up, snap roll, etc... Positive Gs are the result of pulling the nose up from the existing line of flight. A 60 degree level turn requires a 2G force applied to the plane by the pilot back pressure on the stick. An inside loop results in constant positive Gs, but an outside loop is all negative Gs. >1G is created when the aircraft is in equilibrium in straight and level >flight, True. >FLY SAFE!!!
