Landing speed and weight.
Because the gross weight of the Piper Cheyenne depends on how much fuel and cargo are on board, the proper landing speed is not always the same.
The formula:
V=square root of 1.496L gives the landing speed in terms of the gross weight only.
:
a) Find the landing speed if the gross weight is 7000 lb.
V =
V =
V = 102.3 mph is the landing speed
:
b) What gross weight corresponds to a landing speed of 115 ft/sec?
= 115
square both sides
1.496L = 115^2
1.496L = 13225
L =
L = 8,840.2 lb
