WHEELS & BRAKES High performance for Aircraft
Bad brakes = DANGERBad brakes = DANGERWheel locking
Risk of tyre burst, time life reducedStopping distance increased
Risk of runway off-going at landing
Inadequate control of differential brakingImpossibility to stay in line
Risk of runway off-going at landing
MAGNETO CHECK IMPOSSIBLE at the nominal power when run-up checkingNo detection of an engine failure
Risk of engine failure
SHORT TAKE OFF IMPOSSIBLEImpossibility of full throttle with the brakes on
Take off distance increasedRisk of collision with the relief
ROUGH BRAKING Impossibility of controlling the braking power
Risk of nose overfaster wear of the landing gear
WHEELS & BRAKES High performance for Aircraft
Composition of the kit (can vary depending on the aircraft equipped) :ALIR regulator, hoses, master cylinders, brakes calipers and discs, wheels
ALIR PRESSURE REGULATOR allowing a +/- 1 bar maximum reference pressure and an equipressure left-right

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 IN LINE with ALIRHelps the pilots to control the brakingShorter landing at maximum safety and for all the pilots
WHEELS & BRAKES High performance for Aircraft
DANGER: wheel lockingThe pressure overshoots the value allowing the wheel locking. Impossible with ALIR that avoids to lockthe wheels.

WHEELS & BRAKES High performance for 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
Nota: BERINGER brake pads used int 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.
