Why did you bother getting tested in the first place? Does it really matter? This wasn’t my first test. I’ve been tested in the past due to exposure and due to travel.

Translates to something like "do pointless actions but make it look like something is being done". At work we call it “making visual progress”.

If so, what can't be done in hangar other than starting up the engines? I heard WX radar is also harmful to people around when used in closed spaces. Yes, you can align the IRUs.

It seems to me that our MD10's, MD11's and B767's do not have as many strikes as our B757's which seem to be a magnet for lightning strikes. Any thoughts? Gregory My experience is the opposite. In the spring, it seems there’s an MD-11 or a B767 out of service somewhere in our system for a lightning...Jump to post
When I was a flight mechanic with Evergreen, we’d frequently make tech or fuel stops. They’d often park us as a gate, since it was probably more convenient than a hardstand.Jump to post

Isn’t military Jet fuel basically the same thing? Just with a lower freeze point? I mean, military jets use Jet A when they come into a civilian field for refuel.

At previous operators, we would use sump fuel in our GPU’s and air starts. Now, sump fuel is taken away by Plant Engineering. I’ve no clue what they do with it.
Can the equipment run on it? Yes. Is it ‘safe’ to do so? I’ve no clue, I’m not a diesel mechanic.
Just a quick add-on question. For aircraft to be powered up - do you need to switch battery on, or will external power completely do the trick? I could imagine some sort of protection on the battery circuit preventing that, but Bat/GPU running parallel with switch on each seems a simpler solution. ...Jump to post
Most AMMs will have both nose wheel tires changed at a time, it’s not just for ease of work.

Do they require tire rotation and balancing like a regular car? Rotated? No. Balanced at buildup.

It’ll depend on the operator. We have maintenance just about anywhere we fly an aircraft, if it spends more than a couple of hours in the ground. One mechanic, maybe a part-timer to back him up. But, they’re there. We typically use contract maintenance at through stations, and they are only required...Jump to post

Incidentally what do people trim their nose hair with ?!
My suspicion is that it's because the main sensor on a ship of that era was the Mark 1 Eyeball. Communications between stations would have been via tube, nothing electronic. So an open bridge provided a 360 degree view for the bridge officers and any lookouts posted.
Just a guess.
In case of smoke emanating from the main cargo deck due to fire, wouldn't you want a door in between to keep the smoke out as long as possible?

When you see big pieces cut out that way, it tends to mean someone wanted those sections intact to effect a major repair on one of their airframes.

2) why not put some foam on the ground, or water, before the airplane lands so the landing gear doesn't catch on fire?

My personal opinion: an engine is not running if the core is not turning. No N2 (N3); then the engine is not running and it is safe to approach. I’d just about guarantee that the FCOM procedure cited above is related to the core and not the fan. In fact, can you see fan speed (N1) on newer engines w...Jump to post
Tuch the Fan? The fan needs to be just about stopped before you can get a hold of it. Too much mass there.
As for standing in front of the inlet? Almost immediately. The low pressure in front of the fan dissipates within seconds of shutdown.
