Bad brakes = DANGERBad brakes = DANGERWheel lockingWheel locking

Risk of tyre burst, time life reducedStopping distance increased

Risk of runway off-going at landingRisk of runway off going at landingInadequate control of differential braking

Impossibility to stay in lineRisk of runway off-going at landingRisk 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 failureRisk of engine failureSHORT TAKE OFF IMPOSSIBLE

Impossibility of full throttle with the brakes onTake off distance increasedTake off distance increasedRisk of collision with the relief

ROUGH BRAKINGImpossibility of controlling the braking powerImpossibility of controlling the braking power

Risk of nose overfaster wear of the landing gear

EMERGENCY BRAKING : comparison of:- blue curve : with ALIR: the pilot applies full braking without any control (similar to a p pp g y (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 d l ti h thdeceleration when the lift decreases on the wings.
