Change in Angle of Attack due to Upward Gust Solution

STEP 0: Pre-Calculation Summary

Formula Used

Change in Angle of Attack = tan(Gust Velocity/Flight Velocity)
Δα = tan(u/V)
This formula uses 1 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)

Variables Used

Change in Angle of Attack - (Measured in Radian) - Change in Angle of Attack is the change in angle caused due to gust, change in weather patterns, or altitude changes.
Gust Velocity - (Measured in Meter per Second) - Gust velocity is the velocity of the gust, occurs then there is a brief increase in the speed of the wind, usually less than 20 seconds.
Flight Velocity - (Measured in Meter per Second) - Flight Velocity is the velocity of aircraft where the air moves relative to the reference point at the airspeed.

STEP 1: Convert Input(s) to Base Unit

Gust Velocity: 8 Meter per Second --> 8 Meter per Second No Conversion Required
Flight Velocity: 34 Meter per Second --> 34 Meter per Second No Conversion Required

STEP 2: Evaluate Formula
