The Link Trainer: Dealing in a Comprehensive Manner with the Installation, Maintenance, and Adjustment of the Link Trainer Used for the Training of Pilots in Instrument Flying. Compiled by a Panel of Experts. With Sixty-One Illustrations. Advisory Editor: E. W. Knott, M.I.A.E., M.S.A.E.

Octavo, royal blue cloth (hardcover), gilt letters, viii, 132 pp. Very Good, with light edgewear and former-owner bookplate; in a Very Good dust jacket with darkened spine and edges. From dust jacket: The Link Trainer has been found to provide a most valuable accessory to the rapid and efficient training of pilots. It enables men to be trained in the principles of instrument flying, or blind flying, without leaving the ground. The present book not only describes the principles upon which the Link Trainer operates, but deals thoroughly with the work involved in adjusting and maintaining the Trainer equipment at its highest point of efficiency. Details are given for Trainers of Canadian manufacture (type I.D.) as well as for the type (D) manufactured in America. A separate section of the work is devoted to the maintenance and repair of the Kollsman Telegon instruments which are used in conjunction with the Link Trainer equipment. The construction and operation of each instrument is described and clear instructions are given for the carrying out of tests to enable any fault to be rapidly located. From Preface: The expansion of both military and civil aviation which has occurred during recent years has rendered necessary two things. First, a general speed-up in the rate of production of aircraft of all types, and, second, a speed-up in the training of men to pilot these aircraft. Although the manufacture of an aeroplane does not lend itself so completely to the well-known methods of mass production as does the motor-car, nevertheless, it is, comparatively speaking, a much more simple matter to produce, say five thousand aeroplanes of a given type than it is to produce, in an equivalent time, five thousand fully trained pilots capable of flying these aircraft. The Link Trainer has been found to provide a most valuable accessory to the rapid and efficient training of pilots. it enables men to be trained in the principles of instrument flying, or blind flying, without leaving the ground. In effect, it consists of a fuselage with wings and tail unit mounted on universal joint in such a manner as to permit movement in bank and pitch in excess of manoeuvres normally done on instruments. The fuselage can be moved so as to simulate the actual conditions of flying, whilst, at the same time, the instruments show the pilot what are the actual flying conditions at any given instant. The operating mechanism is so designed that bumpiness and storm conditions can be reproduced at will. While in training the pupil is in communication with his instructor through an electrical apparatus which produces radio signals and permits of two-way voice communication. The instructor sits at a desk upon which is a map, where, by means of a special electrical recorder, the course which the pupil would have flown is traced out. The present book not only describes the principles on which the Link Trainer operates, but deals thoroughly with the work involved in adjusting and maintaining the Trainer equipment at its highest point of efficiency.
