It's possible that you could make your idea work. 1. On the ground, Master OFF. 2. Cycle the flaps up and down until they won't move any more. This means that the hydraulic system pressure is zero or close to it. 3. If you can safely jack so as to raise the nose until the nose gear is an inch off the ground, do it. With the mains resting on the ground and chocked, their geometry will keep them solidly locked down (as well as the down locks!). 4. Then you can swing the nose gear passively (rope, push, or whatever technique you choose, as long as the jacking is secure) to do your testing and adjusting. You can move the gear lever to let the hydraulic fluid move in the proper directions. With no pressure, the mains will stay safely down. The reason this will work is that the nose gear strut is vertical. A similar approach will not work for the mains because they swing down as they move after before they swing up into the wells. Be safe. Ted On 6/11/2013 10:30 AM, bronnenmeier@GROBSYSTEMS.COM wrote: > Dear subscribers, > > A friend took a picture of the belly of my airplane in flight with the > gear up.
