Safe To Bank During Turbulence?

Mon Oct 10, 2005 6:36 pm

I just got back from GUM this morning and have a few questions.

Is it safe to bank during turbulence? For some reason I always think it's dangerous. In this case I don't mean mild ~ heavy turbulence, I mean just when it's bumpy up there.

Yes, just with low level wind shear its recommended to have wings level.

In simply "bumpy" air, it's perfectly fine. In heavy turbulence, it would probably not be recommended. It has to do with the load factor on the wings. In still air flight, the load on the wing equals the lift it generates. Significant turbulence can increase load factor. Banking does increase the load factor. Hence, the two together can be undesirable.

However, this is very significant turbulence we're talking about. With light chop, mild, or even moderate turbulence the load factor during a normal bank is nowhere near the airframe's limits. During heavy turbulence, such as inadvertantly flying into a thunderstorm with overhead bins popping open and people hitting their heads on the ceiling it would be advisable to keep the wings level. Obviously, airliners very rarely fly into these conditions where banking would be unsafe.

The banking capabilities of an airliner also depend on it's gross weight and the altitude it is flying at. The term "coffin corner" comes to mind.

Can you explain what this is? Are there certain altitudes you don't want to turn? Or does it have to do with the degree of turn?
