B747 Nose Gear Collapse

[flipside]

I made a clean landing at Atlanta in a 747. I was advised to hold position for a departing aircraft. When I got clearance to proceed my nose gear collapsed. How do I get rid of the jumping when I switch form cockpit to spot view?

Care to tell us which model of 747 - e.g. Posky?

Project Opensky B747-451 Delta

I just did an experiment. I chose to start a flight from KSEA, I went to spot view immediately, I disengaged the parking brake and just sat there for a minute and the nose of the aircraft slowly dropped to the ground with the nose gear sinking into the tarmac. I also noticed that the nose wheel started out about a third into the tarmac.

There are some serious problems with the wheels on all of the Opensky 747's.

Try installing the newest FDE from the POSKY website.

Here's a couple of links:

Try both.

Make sure to backup existing files before you try.

I am profoundly sorry, but the measures you suggested did not solve my problem. In spot view if I am taxiing and stop and start again the nose of the aircraft still drops to the ground.

How is flying? Is it possible the CG is way too much towards the front?

I moved the "empty_weight_CG_position" from -97.0 to -104.0. That seemed to solve the problem and the nose wheel is running on top of the tarmac instead of about 4 feet into the tarmac.
