calcAttack: calcAttack

In WilliamCooper/Ranadu: Functions for use with RAF aircraft data files

Description

Calculate angle-of-attack

Usage

calcAttack(PITCH, VSPD, TASX)

Arguments

PITCH	The pitch angle in degrees
VSPD	The rate of climb of the aircraft in m/s
TASX	The true airspeed of the aircraft in m/s

Details

Assumes vertical wind = 0, finds AOA from pitch, VSPD and TASX. Used to provide a reference value for calibrating gust probes. The radome "calibration" coefficients are usually determined by fitting to reference values provided by this function, so it should be used where it is expected that the vertical wind is zero or averages to zero.
