Also, Newark = Plague....again this week. Please avoid it. Upcoming: A nice planelopnik post on aircraft de-icing

As in you're the de-icer, or the de-icee? I had a side job at Detroit Metro a few years ago de-icing jets. Kinda fun if you're in the boom, not so much if you're the one in the truck who has to get out and use the fire hose on the smaller aircraft.

Getting deiced....again. surounded by wide fields of snowy pavement and a 0 wheel drive.

Have you heard about the deicing issues on a legacy Boeing jet that Boeing just found this year?

You will not hoon it in the snow?
You will not hoon it on the go?
No flaps extended for soft ground?
No time to go and horse around?
Newey would be proud to see,
blown flaps like back in grand prix.
But, alas
No hoon in you. No hoon in you.
No aeronautical tomfoolery will ensue.
How sad this makes me, turns me blue,
To hear there's not a hoon in you. :(

I really want to hop in the plane and try to do donuts. I'm pretty sure I'd get hoon of the day.

Thank you for this. The only thing I would add is FAA action on such....action...

Well, things can happen in the motion simulators just from training...its something I've thought about posting on....

You talking about that 737 that had a near-stall back in November? Or all of the crap the 787 is having?

If the 737 tail trim tab is not set properly before deicing and not deiced properly, the trim mechanism can be destroyed.

Something about the fluid getting in and freezing the input arms to the pcu's for the horizontal stabilizers when trim was fully forward and fluid was applied from the side, right? Nuts that this problem hadn't presented itself yet such that Boeing was, evidently, only JUST realizing it could be a potential problem.

Rats, as soon as I saw "hoon the jet", my mind flashed thru numerous exciting times hooning in the air and I just knew this would be filled with stories of military and civilian aircraft stories. Then again, what's the statute of limitations for violating FAA regulations???
Oh, the stories I could tell... but I have to kill you afterwards.

It's not just on the NEW Boeing planes. Several planes out there have trim tab settings for deice purposes to deflect fluid away from or close off the openings to the internal bellcranks/jackscrews/servomotors/actuators that control the elevator surfaces and trim systems. Usually full nose down trim does it on the planes i've been flying but other planes have other settings im sure, whatever works for those manufacturers. It's really preventing the fluid from getting inside and later on when it cools down in flight causing control stiffness or trim issues.

All I know is, I attended a conference where the Boeing rep said "Every 737 ever made has this de-ice issue."

I don't doubt that at all. Alot of planes have the issues. It's just a setting in the checklists to adjust for that process and it's solved.
