ALIR System - Anti Lock In line Regulator

For complete technical explanation about the ALIR system, please refer to the main page of this site and click on the ALIR technology. 
Most BERINGER complete kits include the limiter / regulator systems. They represent a real advance in term of safety:
- ALIR in case of differential braking:  the in-line balanced anti-lock regulator is installed in the braking circuit limiting the pressure in the circuit at an adjustable value


The ALIR system allows the control of the direction on the ground with differential braking. The system can be installed on certain old aircraft.

EMERGENCY BRAKING : comparison of:

 - blue curve : with ALIR: the pilot applies full braking without any control (similar to a car ABS)
 - red curve: without ALIR: no regulation, the pilot must control the braking
 (in both cases, conditions are the same: same plane, same brakes) Weight of the aircraft: 1200 kg, braking speed: 70 Kt

With the ALIR system installed in the circuit, you keep the direction control when you taxy due to the differential braking. 
The ALIR system can be installed in old braking circuits. 


Nota: BERINGER brake pads used in the ALIR system have a friction coefficient that increases with the temperature allowing an increase of the deceleration when the lift decreases on the wings.
