He was only talking about doing this to allow test flights to be carried out safely, so it wouldn't be a problem - the test aircraft's structure would be reinforced as necessary. This method is...

I've been quite surprised to see a number of posts along these lines recently, basically criticising CRM for empowering whipper-snappers to challenge wise old greybeards. I thought that Tenerife (and...

That has nothing whatsoever to do with how safety-critical software is written for applications such as airliner flight control software, let alone how it's reviewed, approved and certificated. For...

Apart from the fact that the FACs aren't where you think they are, I think you'll also find that the ELACs and SECs are the flight control computers that apply the control laws, and not the FACs.

Exactly what I was thinking - an increase in OAT increases the speed of sound, so the aircraft would be even further away from a Mach limit than before. And IAS is dependent on pressure, not...

Overspeed protection

Could somebody explain to a simple engineer how an air temperature "spike" would cause the aircraft to go into an overspeed protection? I've seen this theory posited to explain an automatic pull-up,...

As has been pointed out, there has been no spin testing of A320s (!) to provide data on which to base a simulation. The reason the simulation behaved in a "totally classic" manner will have been...
