And you base that statement on what exactly? I could as well say that I've calculated that 42 dollars will be enough to take care of all the leftover nuclear waste forever.

Absolutely quantitative except when airspeed is low, when weight is non-standard and when load factor is not 1. I guess you and I disagree on the definition of "absolutely".

The pilot can "know whether he's close to stall without anything more than an airspeed indicator" only if he's not in a turn (see accelerated stall). While you are right in theory - if you knew the load factor and indica

Since angle of attack is by definition the angle between a reference line of a body and the fluid it is moving through, I fail to see how you could measure it without measuring the relative motion of the fluid. Your suggestion would work un
223.
by bbojan 8y ago
Angle of attack is not related to any of the items that you list. You could be approaching stall even while your altitude is increasing (2), while you are at a high speed (3), at less than 1 G (5) etc. I'm not sure you quite understand

Preventing a stall is not what the job of MCAS is. (edit: clearer language)

Do you have a reference for that statement? Because the story that I heard is that he purposefully commanded max pitch knowing that alpha protection would prevent the airplane from stalling, as his landing speed would be lowest at max AoA.

Why? I tend to enjoy informed speculation, that's one of the reason I visit this website. Isn't speculation one of the things that characterizes us as humans?

I hated DST, but now that I have kids I really like it - it means in the summer I have one more hour of sunlight to play with them outside after I come back from work.

Berlin has 26 subway lines. Some of them (S-Bahn) interconnect with intercity rail, so there are times when you can transfer from a subway to a train on the same platform . I would really like to know what makes you think Berlin public tra

Because 0G is a (slightly imprecise) term for weightlessness, and weightlessness is by definition when the only force acting on a body is the gravitational force. If you're in an elevator, and the elevator cable snaps, you'll be i

As I believe that Earth is the only life-bearing planet in our galaxy, if not the whole Universe, I'm extremely saddened with news like this of a near-extinction of yet another fascinating species. My only hope is that humanity will sp

Be careful, this is not correct and is a common misconception. You cannot turn mass into energy or energy into mass. This would violate not one, but two fundamental laws of physics - conservation of energy and conservation of mass. A more

Grassland, if properly managed, can sequester more carbon than a forest. This is related to the (unintuitive) fact that grasses are more efficient producers of organic matter than trees. Joel Salatin has done some great work related to this

I think the problem with most of the layouts is that they are typist-oriented (e.g. people who enter mostly English text), so they mainly focus on the letters. Programmers' workflow is different. I'm in the process of switching to

This is a great question! From my understanding, Quantum Field Theory posits that what we think of as particles are actually excitations of the underlying fields. So when a neutron decays into a proton and an electron, it doesn't mean
