This landings. The standard approach and landing chapter reviews some basic features of the earths system installed at airfields around the world is geometry as it relates to navigation, and the instrument landing system ILS. Chapter 12 introduces some basic aircraft navigation describes how the ILS can be used for approach terminology, e. The ILS uses a combination reckoning etc.

The chapter concludes by of VHF and UHF radio waves and has been in reviewing a range of navigation systems used on operation since Many Chapter 13 continues with the theme of guided aircraft navigation systems utilise radio frequency approaches to an airfield. There are a number of methods to determine a position fix; this links shortcomings with ILS; in the microwave very well into the previous chapters of the book landing system MLS was adopted as the long- describing fundamental principles of radio term replacement.

The system provides that is still in use today. ADF is a shortmedium multiple approach angles for both azimuth and range nm navigation system providing elevation guidance. Despite the advantages of directional information. Military reviews some typical ADF hardware that is fitted operators of MLS often use mobile equipment to modem commercial transport aircraft, and that can be deployed within hours. These systems are based Preface XIII on hyperbolic navigation; they were introduced in Navigation by reference to the stars and planets the s to provide en route operations over has been employed since ancient times; aircraft oceans and unpopulated areas.

Several hyperbolic navigators have utilised periscopes to take systems have been developed since, including celestial fixes for long distance navigation. An Decca, Omega and Loran. The operational use of artificial constellation of navigation aids was Omega and Decca navigation systems ceased in initiated in and referred to as Navstar and respectively.

The aim has been to make the subject material accessible and presented in a form that can be readily assimilated. The book assumes a basic understanding of aircraft flight controls as well as an appreciation of electricity and electronics broadly equivalent to Modules 3 and 4 of the EASA Part syllabus.

It is important to realise that this book is not designed to replace aircraft maintenance manuals. Nor does it attempt to provide the level of detail required by those engaged in the maintenance of specific aircraft types. Instead it has been designed to convey the essential underpinning knowledge required by all aircraft maintenance engineers. Chapter 1 sets the scene by providing an explanation of electromagnetic wave propagation and the radio frequency spectrum. The chapter also describes the various mechanisms by which radio waves propagate together with a detailed description of the behaviour of the ionosphere and its effect on radio signals.

Antennas are introduced in Chapter 2. This chapter explains the principles of isotropic and directional radiating elements and introduces a number of important concepts including radiation resistance, antenna impedance, radiated power, gain and efficiency. Several practical forms of antenna are described including dipoles, Yagi beam antennas, quarter wave Marconi antennas, corner reflectors, horn and parabolic dish radiators.

Chapter 2 also provides an introduction to feeders including coaxial cable and open-wire types , connectors and standing wave ratio SWR. The chapter concludes with a brief introduction to waveguide systems. Radio transmitters and receivers are the subject of Chapter 3. This chapter provides readers with an introduction to the operating principles of AM and FM transmitters as well as tuned radio frequency TRF and supersonic-heterodyne superhet receivers.

Selectivity, image channel rejection and automatic gain control AGC are important requirements of a modern radio receiver and these topics are introduced before moving on to describe more complex receiving equipment.

Modern aircraft radio equipment is increasingly based on the use of digital frequency synthesis and the basic principles of phase-locked loops and digital synthesisers are described and explained.

Very high frequency VHF radio has long been the primary means of communication between aircraft and the ground.

Chapter 4 describes the principles of VHF communications both voice and data. The chapter also provides an introduction to the aircraft communication addressing and reporting system ACARS. High frequency HF radio provides aircraft with an effective means of communicating over long distance oceanic and trans-polar routes.

In addition, global data communication has recently 12 xii been made possible using strategically located HF data link HFDL ground stations. Chapter 5 describes the principles of HF radio communication as well as the equipment and technology used.

As well as communication with ground stations, modern passenger aircraft require facilities for local communication within the aircraft. Chapter 6 describes flight-deck audio systems including the interphone system and allimportant cockpit voice recorder CVR which captures audio signals so that they can be later analysed in the event of a serious malfunction of the aircraft or of any of its systems.

The detection and location of the site of an air crash is vitally important to the search and rescue SAR teams and also to potential survivors. Chapter 7 describes the construction and operation of emergency locator transmitters ELT fitted to modern passenger aircraft.

The chapter also provides a brief introduction to satellite-based location techniques. Chapter 8 introduces the subject of aircraft navigation; this sets the scene for the remaining chapters of the book. This chapter reviews some basic features of the earth s geometry as it relates to navigation, and introduces some basic aircraft navigation terminology, e.

The chapter concludes by reviewing a range of navigation systems used on modern transport and military aircraft. Many aircraft navigation systems utilise radio frequency methods to determine a position fix; this links very well into the previous chapters of the book describing fundamental principles of radio transmitters, receivers and antennas. Radio waves have directional characteristics as described in the early chapters of the book.

This is the basis of the automatic direction finder ADF ; one of earliest forms of radio navigation that is still in use today. ADF is a short medium range nm navigation system providing directional information.

Chapter 9 looks at the historical background to radio navigation, reviews some typical ADF hardware that is fitted to modern commercial transport aircraft, and concludes with some practical aspects associated with the operational use of ADF.

Preface During the late s, it was evident to the aviation world that an accurate and reliable shortrange navigation system was needed. Since radio communication systems based on very high frequency VHF were being successfully deployed, a decision was made to develop a radio navigation system based on VHF.

This system is in widespread use throughout the world today. VOR is the basis of the current network of airways that are used in navigation charts.

Chapter 11 develops this theme with a system for measuring distance to a navigation aid. The advent of radar in the s led to the development of a number of navigation aids including distance measuring equipment DME. The system is based on secondary radar principles.

These navigation aids cannot however be used for precision approaches and landings. The standard approach and landing system installed at airfields around the world is the instrument landing system ILS. Chapter 12 describes how the ILS can be used for approach through to autoland.

There are a number of shortcomings with ILS; in the microwave landing system MLS was adopted as the longterm replacement. The system is based on the principle of time referenced scanning beams and provides precision navigation guidance for approach and landing.

MLS provides threedimensional approach guidance, i.
