Airbags can be used to lift astronomically huge payloads. 100 psi across a 36X36 bag is 129,600 pounds of lifting force. Meaning...a simple garage compressor most of us probably own can supply a 3 foot by 3 foot airbag with enough force to lift many fully loaded airplanes by itself...but obviously the balance would be off so you would use multiple bags for stability.I wonder how long it will take to clear that runway.
Am I correct in supposing they'll probably be able to lift the airplane with those huge airbags and pull the gear down?
Apparently. Without being qualified on the 76 ER, ETOPS, NAT requirements or the LOT Ops Specs it's difficult to comment.Yet they crossed the ocean like that.....
You do have redundancy with two systems available, one hydraulic system out is not an emergency nor cause to divert. This was a non event until they activated the alternate gear extension and nothing happened, their though process wasn't at all one of doing a belly landing but rather at what weight they were going to do a flaps 20 landing, go back or do it 70,000lbs lighter.
