Glide angle for given lift-to-drag ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Glide Angle = atan(1/Lift-to-drag Ratio)
θ = atan(1/LD)
This formula uses 2 Functions, 2 Variables
Functions Used
tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)
Variables Used
Glide Angle - (Measured in Radian) - Glide Angle is defined as the angle made by the glide flight path with the horizontal.
Lift-to-drag Ratio - The Lift-to-drag ratio is the amount of lift generated by a wing or vehicle, divided by the aerodynamic drag it creates by moving through the air.
STEP 1: Convert Input(s) to Base Unit
Lift-to-drag Ratio: 6.61 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
θ = atan(1/LD) --> atan(1/6.61)
