Flight Instuments – Index

Pilots receive information about the state of their aircraft like its speed, altitude, position and attitude through instruments and displays. These can vary from the simplest of dials and pointers to modern electronic displays. Depending on the vintage and the complexity of the aircraft, and a simple dial can seem very different in appearance and sophistication from a modern cathode ray tube or liquid crystal screen. However, certain problems of range, resolution, accuracy and reliability are general characteristics of all instrumentation systems. We shall discuss the various instrumentation used in…

Radio Navigation – Index

The discussion on Radio Navigation starts with the basics of Radio waves and propagation. Basic Radar Theory is examined next right from the principles to the airborne use of primary and secondary radar systems. Thereafter, we shall learn about the various Radio Navigational Equipments used in Mordern Aircrafts. In the category of Radio Navigation, we would understand the principles and use of basic Radio Aids to Navigation like Ground D/F, ADF, VOR, DME, ILS and MLS. Finally, we shall provide a overview of advanced cockpit intrumentation like GPS and FMS.…

General Navigation – Index

General navigation in aviation involves the process of determining and maintaining the aircraft’s position, course, and altitude during a flight. In this subject we would learn about the methods, instruments and techniques to ensure safe navigation of aircraft. General Navigation is the most basic form of navigation, since it has been in vogue before the Radio Navigation Aids were invented. In this category, we shall understand the various aspects of General Air Navigation under the following topics. Direction, Latitude and Longitude Great Circles, Rhumb Lines & Directions on the Earth…
