Re: wavy line on airbus wings

On the trapezoidal skin section between the flaps, where the yehudi ends, on many A319s and A321s, what is the purpose of the distinctive wavy line where the skin thickness apparently increase, towards the rear of the section? To affect the boundary layer separation? To avoid fluttering of that thi...

Re: Wife and Husband Flight Crew

On an AA flight a few weeks ago I was surprised when the FO made the preflight announcement and stated that the captain was his wife. I was surprised because I would have thought that people in intimate relationships wouldn't be allowed to fly together. I would think that if a couple had an argumen...

Re: A340-600 vs A350-1000 Boogies

What’s interesting is the wheels on the rear bogie of the A350-1000 do not steer like those on all versions of the 777, with such a long aircraft you’d expect Airbus to incorporate that feature Indeed. It does affect tyre and landing gear wear. AFAIK the decision to not make them steerable was base...

Re: Turbofan Cool Down Time

AFAIK it mostly has to do with lubrication. While the engine is still warm you need the oil to continue circulating efficiently. It doesn't affect the turnaround directly. It affects the time after you land (technically "after high thrust operation") until you can shut the engines off. In ...

Re: A340-600 vs A350-1000 Boogies

The A350-1000 is a triple axle (6 wheel) designed MLG. The A350-900 is a double axle (4 wheel) MLG. The triple axle configuration was added due to the increase in Gross Weight. It bears mention that the A350-1000 wheels are much smaller than the A350-900 ones, so the difference in wheel well size i...

Re: Are commercial airline pilots the highest paid profession in the USA?

More interesting question, how do US pilot compensation compare EU or Asia? There are 2 ways to think about that question.

Re: Flat tyre dollys?

We can taxi with two wheels deflated on a main gear, with a low speed limitation.

1. Never seen one. If a wheel needs changing it is changed.
2. I imagine this is it. To clear a runway or taxiway.
3. Towbarless tugs are in wide use. They are essentially mechanised dollies.

I can't point to any one approach, but I have a few I really enjoy. HKG ILS 25R with RNAV transition on a clear day.

We can feed the packs from the high pressure air carts (airstarts as we call them, pilots call them huffers), however at my company that practice is forbidden and we wouldn’t want to do it anyway as those units are very loud and clumsy to maneuver around.

My thoughts, and I could be wrong, but I get the feeling that an APU has much more oomph than it actually needs under most circumstances. Certainly, it will cool the cabin quickly even in really hot weather. You may be right about "in most circumstances" but I do a lot of flying to the Ca...
