Good momentum — keep clearing them; a miss just comes back until you nail it.
The angle of attack at which an airplane wing stalls will

Incorrect.

Wait — so why does a heavier plane stall at a higher airspeed then?

Good question — that’s one of the parts that confuses a lot of people. To hold altitude, your wings have to make lift equal to the airplane's weight. A heavier airplane needs more lift, and lift comes from speed and angle of attack together.

The wing still stalls at that same fixed critical angle. So to make the extra lift, you have to reach that angle at a higher airspeed. The stall angle never moved — your stall speed did.

Review · Question 1 of 60 Blank Takeoffs, Landings, and Go-Arounds
Who has final authority to accept or decline any land and hold short (LAHSO) clearance?
A.Pilot in command.Correct
B.Air Traffic Controller.
C.Second in command.
You left this one blank.
Ovi explains
Per the Aeronautical Information Manual (AIM) 4-3-11(b)(3), the pilot-in-command has the final authority to accept or decline any LAHSO clearance, and the safety and operation of the aircraft remain the pilot's responsibility. This is reinforced by 14 CFR § 91.3(a), which makes the PIC the final authority for the operation of the aircraft.
ACS: PA.IV.B.R3b
