PDX-HNL is fighting against the wind over the ocean, so it's going to be a long ride at certain times of the year. Has nothing to do with the aircraft. Also "movement of the fuel" really dude? Come on.
Why the bashing? Dude! If you've never been on an aircraft full with fuel, that when the pilot turns onto a runway and advances the throttle that you've never felt the weight displacement in an aircraft that is at it's comfortable operational limits, then you've not been paying attention. SMH.
If you disagree fine, don't be a douche about it. Used to be people could relay a memory here & the most would also enjoy, now you've given me an attitude like I'm lying, well you can pop that up your [email protected]
@. I have no reason to lie, I am not lying & you sirs are a fool, by missing out on one of the best parts of a flight. IMO. You don't have to believe it, but don't start saying I'm telling tales. got it?
I was just about to chime in and suggest a step stool to help the triggered posters above dismount off their high horses.
While I can’t be positive it was due to fuel vs something else, I too feel like I’ve felt this phenomenon, but on a 772. I feel like it’s most noticeable during tight turns, like lining up for the center line.
I think the posters who would scoff at RWA’s comments ought to consider that a commercial airliner near max fuel has tens of thousands of pounds of liquid fuel in the wings. Liquids at those volumes shifting around is going to have some momentum to it. Consider the fact that mere inches of moving water in flood conditions can sweep away 4-5,000 lb cars. Consider the effect the weight of fuel has on the wings of aircraft operating long haul. It is not uncommon to see the wings of heavily fueled aircraft sagging/drooping due to the fuel weight. Can you honestly say that much weight shifting couldn’t be felt?
Hell, I’ve felt planes yaw side to side sitting at the gate while ULDs are being positioned in the hold or loaded/unloaded. Fuel is magnitudes heavier than ULDs even when maxed out. I suppose I’m crazy too ?
77H thank you for your post, it certainly reinforces what I was saying, there was another pleasent & helpful comment (it was removed by admin of course), from PDXPOL who had just had a conversation at PDX with an AS pilot who did confirm my assertion once again, especially on the 900ER model. The jist of his posting is below.
You are correct that you would have felt that same on other airliners when departing for flights that are long haul for the plane being flown. If the pilot has an unrestricted takeoff, he or she will start spooling up the engines, then turn onto the runway & there is a certain amount of listing to one side as fuel moves in their respective tanks.This can also be felt if, while taxiing & the plane stops quickly, say waiting in line to take off, you can feel fuel movement just after the brakes are applied. It's high school physics, not rocket science. I can feel fuel move in my truck with the double tanks full too.
Lastly, If you don't believe it, it doesn't mean that it doesn't exist, best thing I can advise is, you best be sure you know what you are talking about, before calling out another member a liar. TY!
