You sound like an EXCELLENT advocate for having the ability to dump fuel too!!! Why are you in such a hurry to dump fuel? Doing that starts to limit your time / options available for trouble shooting the problem and diverting to another airport. The first two memory items on any emergency checklist a 1. FLY THE AIRPLANE 2. DON'T HURRY Dumping fuel violates #2. Besides, IF you really need to land in a hurry, the A320 can do that at any weight. These guys took off for NY with a full load of passengers. That means that they had a lot of fuel onboard and a heavy takeoff weight. To land at that weight would have required a much higher landing speed. Since they had the hydraulics (green system) turned off to the nosewheel steering system, (per emergency checklist) this also reduced their braking ability because this same hydraulic system also controls the #1 engine reverse, and normal braking, i.e. antiskid assisted braking. To me it's perfectly clear, that there was no need for the JetBlue A320 to dump fuel. Burning it was a much better option. But I can still imagine emergencies, where one cannot afford to fly around for several hours, yet still a reduced landing weight, lower than the allowable maximum, and less fuel onboard (the fireball thing ..) would be desireable. Say some sort of fire or smoke developing onboard, for example, like the swissair accident, maybe in combination with some structural damage. I would expect that dumping fuel just before the landing would greatly reduce the risk of a big fireball. However, the question is of course again, how likely is an event like this, where fuel dumping even below max landing weight would be an advantage and what is the cost and weight for the device. regards, Friedrich -- for personal email please remove 'entfernen' from my adress |
