PNEUMATIC STARTING SYSTEM - DESCRIPTION AND OPERATION 1. General A. The pneumatic starting system provides means for rotating the engine to the rpm range where starting can be accomplished when fuel and ignition are supplied. B. The system consists of two pneumatic starters two starter valves, and the associated pneumatic plumbing. It is controlled by two start switches, located on the forward overhead panel. For component location, (see Fig. 1). C. With air pressure in the pneumatic manifold, actuating the engine start switch will supply electrical power to open the starter valve. Low pressure air acts on the turbine blades of the pneumatic starter causing it to rotate. Rotation of the starter is transmitted to the N2 compressor through the accessory drive gear system. When the engine has accelerated to starting speed, application of fuel and ignition, by advancing the start lever, result s in the engine starting. For engine start procedure, see Chapter 71, Power Plant. At starter cutout speed, electrical power is interrupted mechanically, the starter valve closes, and the starting cycle is ended. D. The pneumatic starting system can use low pressure air from three separate sources. Normally, the engines are started with bleed air from the auxiliary power unit (APU). Secondly, the low pressure air can be obtained from a ground source through the ground pneumatic connection (See Fig. 1). The third source of low pressure air is the cross-bleed air from an operating engine. The cross-bleed starting is not desirable because the operating engine must operate at approximately 80% power setting to develop adequate air pressure for starting the other engine. 502 Feb 15/67 BOEING PROPRIETARY - Copyright . - Unpublished Work - See title page for details. 80-11-0 Page 1
