____________________________________________________________
 1. General
_______ (Ref. Fig. 001) The Alternate braking with anti skid associates the Yellow high pressure with the anti skid regulation. You get this mode automatically:
 -if Green pressure is not available or falls during braking,
 - or if certain failures occur on the Normal system (Ref. 32-42-00).
 A hydraulic selector causes changes between the Green and Yellow systems
 automatically.
 You control only with the pedals. An auxiliary low-pressure hydraulic-system
 transmits the orders. The pressure supplied to the left and right brakes is
 shown on a brake Yellow-pressure triple-indicator installed on the center
 instrument panel.
 The anti skid system and related indicating are operative.
 This braking mode uses the second set of pistons of the brake unit.
