As a consequence, the B-47 was the first mass-produced aircraft to be equipped with an anti-skid braking system.

Six demonstrator aircraft fitted with 11 seats, wing spoilers and an anti-skid braking system.

Anti-skid braking systems use sensors to control the brakes, while cruise control affects throttle position.

The Braking System The anti-skid braking system uses similar principles.

Like the anti-skid braking systems that are becoming more common, a traction control system uses sensors that detect when a wheel is about to start spinning.

The port nose wheel carries speed generators for the anti-skid braking system which prevents brake activation until nose and main wheels are rotating at the same rate.

All three of the aircraft's instrument landing systems as well as the anti-skid braking system were unavailable for the landing; the pilots subsequently landed the aircraft without using those systems.

The flight crew shut down both engines but this action disabled the anti-skid braking system, and during the landing rolls the inner tires on both main gear legs burst almost simultaneously.

Pilots of the early A-7s lauded the aircraft for general ease of flying (with the exceptions of poor stability on cross-wind landings and miserable stopping performance on wet runways with an inoperative anti-skid braking system) and excellent forward visibility but noted a lack of engine thrust.

RG-12 Mk2 - improved version with an auxiliary power unit driven air conditioning system for effective climate regulation in extreme conditions, provision of a central tyre inflation system enhancing mobility by allowing inflation or deflation of the tyres according to terrain requirements, an anti-skid braking system and various ergonomic modifications to ensure crew comfort.
