mechanics, and goes on to cover topics such as air and airflow, aerofoils, thrust, level flight, gliding, landing, performance, manoeuvres, and stability and control. Important aspects of these topics are illustrated by a description of a trial flight in a light aircraft.
Volume 8 – Principles of Flight (JAR Ref 080) Table of Contents. CHAPTER 8. Stalling. Introduction...................................................................................................................................................8-1. Separated Airflow
The principles of flight discussed in this chapter are intended primarily for beginning pilots, and are not intended as a detailed and complete explanation of the complexities of aerodynamics. FORCES ACTING ON THE AIRPLANE IN FLIGHT When in flight, there are certain forces acting on the airplane.
Pressure altitude can be defined as the vertical distance from the 1013.25 hPa pressure level. When the term 'altitude' appears in Operating Data Manuals (ODMs) and performance charts, it...
A) is the total pressure plus the dynamic pressure. B) decreases in a flow in a tube when the diameter decreases. C) is the pressure in a point at which the velocity has become zero.
15 In straight and level flight, the free stream airflow pressure, compared to that flowing under the wing, is: [A] Equal. [B] Equal pressure but travelling faster. [C] Lower. [D] Higher. 16 If the cross sectional area of an airflow is mechanically reduced: [A] The velocity of the airflow remains constant and the kinetic energy increases.
Since air is a gas, it responds to changes in temperature, elevation, and latitude (owing to a non-spherical Earth). Air pressure decreases naturally as we rise in the atmosphere, or up a mountain, we must make correction to the air pressure owing to elevation above sea level.
