What is coffin corner
Coffin corner is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep an airplane in stable flight.

glideslope descent rate rule of thumb:
airspeed x5
What is Mach tuck
anywhere from 0.75 Mach to 1.2 Mach. When the first molecule reaches speed of sound, shockwaves form. Aerodynamic center moves aft, As air flows from the supersonic region in front of the shockwave, to the subsonic region behind the shockwave, it separates and becomes turbulent.
three factors that affect VMC:
density altitude, Gear, "keel" affect. CG
Flaps are
electrically operated

What is a hung start
A hung start occurs when the engine lights off normally but doesn't accelerate to idle RPM. This is usually the result of insufficient power to the engine from the starter.
What is a hot start
If the engine experiences unusual difficulty accelerating during start, a hot start may occur. There won't be enough airflow to cool the initial combustion of fuel within the engine. Acceptable temperature and time limits are published within individual aircraft flight manuals to prevent engine damage.
How to recover from Mach tuck
Recovery can be attempted by lowering the gear, extending the dive brakes, and lowering the flaps. Drag needs to be increased. Recovery is sometimes impossible
What is mcrit
When Mach number equals 1 (speed of sound).. aircraft will begin Mach buffet
