Glide angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Glide Angle = atan(Drag Force/Lift Force)
θ = atan(F_D/F_L)
This formula uses 2 Functions, 3 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.
Drag Force - (Measured in Newton) - Drag Force is the resisting force experienced by an object moving through a fluid.
Lift Force - (Measured in Newton) - The Lift Force, lifting force or simply lift is the sum of all the forces on a body that force it to move perpendicular to the direction of flow.

STEP 1: Convert Input(s) to Base Unit

Drag Force: 15.11 Newton --> 15.11 Newton No Conversion Required
Lift Force: 100 Newton --> 100 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ = atan(F_D/F_L) --> atan(15.11/100)

Evaluating ... ...

θ = 0.149965568243607

STEP 3: Convert Result to Output's Unit

0.149965568243607 Radian --> No Conversion Required

FINAL ANSWER

0.149965568243607 ≈ 0.149966 Radian <-- Glide Angle

What is Glide ratio in aviation?

The Glide ratio of an aircraft is the distance of forward travel divided by the altitude lost in that distance.

How to Calculate Glide angle?

Glide angle calculator uses Glide Angle = atan(Drag Force/Lift Force) to calculate the Glide Angle, The Glide angle formula it is the angle between the horizontal plane and the flight path of the aircraft during gliding flight, it represents the angle of descent or descent rate of the aircraft relative to the horizontal. Glide Angle is denoted by θ symbol.

How to calculate Glide angle using this online calculator? To use this online calculator for Glide angle, enter Drag Force (F_D) & Lift Force (F_L) and hit the calculate button. Here is how the Glide angle calculation can be explained with given input values -> 0.066004 = atan(15.11/100).

FAQ

What is Glide angle?

The Glide angle formula it is the angle between the horizontal plane and the flight path of the aircraft during gliding flight, it represents the angle of descent or descent rate of the aircraft relative to the horizontal and is represented as θ = atan(F_D/F_L) or Glide Angle = atan(Drag Force/Lift Force). Drag Force is the resisting force experienced by an object moving through a fluid & The Lift Force, lifting force or simply lift is the sum of all the forces on a body that force it to move perpendicular to the direction of flow.

How to calculate Glide angle?

The Glide angle formula it is the angle between the horizontal plane and the flight path of the aircraft during gliding flight, it represents the angle of descent or descent rate of the aircraft relative to the horizontal is calculated using Glide Angle = atan(Drag Force/Lift Force). To calculate Glide angle, you need Drag Force (F_D) & Lift Force (F_L). With our tool, you need to enter the respective value for Drag Force & Lift Force and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Glide Angle?

In this formula, Glide Angle uses Drag Force & Lift Force. We can use 1 other way(s) to calculate the same, which is/are as follows -
