Question

What is the correct formula for dimensionless rate of climb?

(a) ν=\(\frac{dH/dt}{V_{md}}\)

(b) v=\(\frac{V_{md}}{dH/dt}\)

(c) v=\(\frac{-V_{md}}{dH/dt}\)

(d) v=\(\frac{-dH/dt}{V_{md}}\)

I got this question by my college director while I was bunking the class.

I want to ask this question from Climb and Descent Performance with Thrust-Producing Engines in division Climb and Descent Performance of Aircraft Performance

Answer 1

The correct option is (a) ν=\(\frac{dH/dt}{V_{md}}\)

The best I can explain: The correct formula for dimensionless rate of climb is given by the formula v=\(\frac{dH/dt}{V_{md}}\) where v the dimensionless rate of climb is and dH/dt is vertical velocity and Vmd is velocity. The vertical velocity dH/dt is given in feet/min.
