Im hoping that this is a simple answer but ill ask it anyways :)Ive noticed looking at several photos of the 747 that the back wheels of the landing gear hang lower than the front. Is this because when the aircraft is landing the back wheels are the first to touch down and on take off the last to lift off? Or is it down to the bank of the aircraft and the weight pushes the wheels down? lets say the aircraft was a level flight with the landing gear down would the back wheels still be slightly lower? Were they designed that way, also does the landing gear have suspension settings? Sorry for all the questions just noticed it myself and its also modelled in the PMDG 747

Paul,The main gear trucks are hydraulicly tilted.cheersTon

The main wheel bogies are tilted. Presumably to soften the arrival. When the gear is retracted the bogies are hydraulically tilted back to a normal position for retraction so as to fit in the wheel wells. Failure to do so can cause significant damage. If the gear does not tilt you will get an EICAS msg GEAR TILT and it the gear lever will not move up. Also for steering the main body gear turns hydraulically (No. 1 sys) to allow for tight turn radii. The "suspension" is not adjustable but the gear struts are pressurised using nitrogen and this needs to be checked every so often to ensure the strut works correctly (just like an adjustable air shock in a car).CheersSteve

It does not appear that anyone ever responded to your question. The rear set of bogies is designed to extend lower than the front set prior to landing. This should occur during all landings.I am not aware of any suspension settings...there are maximum landing speeds based on aircraft weight and the ability of the gear legs to support the landing forces is one of the factors in that equation.
