Re: China Eastern 737-800 crashes in Guangxi, southern China

One thing I have not seen mentioned here is that the G-Forces may have incapacitated the pilots regardless of how trained they were. Surely G-Forces would have been intense in the freefall?

Simple answer: statistics. On average, smoking has lots of deleterious effects on people. Doesn't mean everyone will suffer those effects.

Re: Approach lights

For whatever reason, I love approach lights. Some random observations of US airports: 1.) ALSF-1 seems to occur primarily at military airports, with MALSR/SSALR and ALSF-2 appearing at civil airports. 2.) There is at least one runway (27 at BOS) that has an ILS, but no approach lights (aside from Ru...

However, I was talking about standard turn rates.

Re: What degree of bank angle is used by jetliners when making large wide turns?

You won't see higher bank angles than around 30 degrees typically. At airliner speeds that would lead to unacceptably high g forces for passenger comfort. Aren't g-forces completely independent from the speed of the aircraft? i.e., would you not feel the same 1.5g in a 45 degree bank at 70 knots in...

Re: Altimeters, static pressure, and lift

No, the units for force and pressure are not the same. A force applied over an area is by definition a pressure. Newton (force) per meter squared (area).
