B737-300 Simulator Brakes Fidelity
The local B737-300 simulator displays a very marked and quite alarming juddering from the hydraulic jacks when max braking is applied either on RTO, Max Autobrakes on landing or max manual brakes. The instruments become a blur due to the high frequency oscillation. Judging from the reactions of new pilots to the simulator it is quite alrming to them too.
The techs advise this replicates full anti-skid operation. I am sceptical about this as all the other 737 sims I have flown have never displayed such savage braking characterstics. I would appreciate views from simulator instructors and students who have had the occasion to use max braking on their simulators. Remember, this is not a mild judder associated with simulated anti-skid operation, but a wild ride of massive high frequency oscillation until the aircraft stops.
