A dangerous change in an aircraft's pitching tendency at transonic speeds; also known as "tuck-under".
Could an airliner exceed Mach 1 in a zero-G power dive and safely recover?
(I looked for duplicates. I really did.) Being as it is that "safety" and this are mutually exclusive: I am stupid. I take a cruising A320, apply TOGA power, and push zero Gs until I exceed ...
Why this P-51 limitations placard for diving?
I noticed that this placard has different diving speeds related to altitud. My guess is that those values are a safety speed to prevent going into regions close to Mach 1. I know that the speed of ...
Why do 20-series Learjets have such an extreme susceptibility to mach tuck?
Mach tuck is a change (usually nosedown) in an aircraft’s pitching tendency during transonic flight relative to its pitching tendency in below-transonic flight, caused by the appearance of areas of ...
Are there any airliner crashes that can be definitively attributed to Mach tuck?
Mach tuck (the tendency of aircraft to develop an increasingly nose-down pitching moment at speeds above its critical mach number) caused a number of crashes of high-speed fighter aircraft before the ...
How does the pitching moment change as the speed of A/C approaches critical Mach number?
In an aircraft performance course, I saw that pitching moment goes backwards as the speed of A/C approaches critical Mach number. In fact, that results in nose down pitching moment. But, according to ...
