The Aeroplane Speaks. Fifth Edition

UNDERCARRIAGE.--The undercarriage must be very carefully aligned as laid down in the specifications. 1. The aeroplane must be placed in its flying position and sufficiently high to ensure the wheels being off the ground when rigged. When in this position the axle must be horizontal and the bracing wires adjusted to secure the various set measurements stated in the specifications. 2. Make sure that the struts bed well down into their sockets. 3. Make sure that the shock absorbers are of equal tension. In the case of rubber shock absorbers, both the number of turns and the lengths must be equal.
