Abstract :
A recently developed algorithm which is being used to compute an aircraft reference altitude from air data inputs is accurate in a stationary column of air. However, pressure gradients in the atmosphere can introduce significant errors. An improvement (which corrects for pressure gradient errors) has been developed which is based on the equilibrium equation for the motion of the air mass in the presence of pressure gradients.
