Question

The formula for ground run is given by the formula __________

(a) SG=\(\frac{V_{LOF}^2}{2g(A+BV^2)_{V_{LOF}}}\)

(b) SG=\(\frac{V_{LOF}^2}{2g(A+BV^2)_{0.7V_{LOF}}}\)

(c) SG=\(\frac{V_{LOF}^2}{2g(A-BV^2)_{0.7V_{LOF}}}\)

(d) SG=\(\frac{V_{LOF}^2}{2g(A-BV^2)_{V_{LOF}}}\)

This question was posed to me in homework.

This interesting question is from Estimation of Take-off Distances topic in division Take-off and Landing Performance of Aircraft Performance

Answer 1

Correct choice is (c) SG=\(\frac{V_{LOF}^2}{2g(A-BV^2)_{0.7V_{LOF}}}\)

The best I can explain: The formula for ground run is given by the formula SG=\(\frac{V_{LOF}^2}{2g(A-BV^2)_{0.7V_{LOF}}}\) where

V is velocity

G is acceleration due to gravity

A and B are constants.
