braking problem ??
Well just to say it all depends what kind of brake problems. Just to give some examples.Quite some years back our company had an aircraft taking off from porto santo an military base just outside of canary island.The type of aircraft was an md83.The aircraft taxied out from the apron but appearently one brake did not release,the aircraft were fully loaded and heading norht toward sweden.During the long taxi out one of the brakes were locked and made an mile long black stripe along the apron and taxiway by the locked wheel.Nobody noticed this ,also the crew.Then the aircraft took off and around 80kts the light "wheel not turning" came on followed by (afew ? ) second/s later by a big bang when the exploded tire went thru the airintake and smashed one of the engine.At that time they were traveling around 120kts and they attemt to stop prior rotation-The weather were sunny and warm and they managed to stop on the rwy with some small fire coming from both tires exploaded and the aircraft came to rest at the end of the rwy limped down on one side and shafed all the way to the sliding member (wheel attachment) on one side.All crew and 167 passanger evacuated thru exits normally.But that were in a sunny day with dry surface.Another incident around 10 years later we had an fokker 100 landing in Italy were the crew had selected autobrake for landing as normal.The only problem at that time were that the brakes for some reason went to full RTO braking and did not release-Aircraft stoped rather fast.... and the crew could not release the brakes to taxi in.They were standing at the fist part of the RWY with smoking brakes and and after a couple of minutes all the tire bursts due to ovht and melt plugs melting,as is should be,Aircraft were later towed to the ramp for replacing of various components and wheels and brakes.Also this happened in good condition.This incident (continental) as far as I can see is in snowy conditions and any serious incident like this would make it hard or impossible to stay on rwy.But anyway my experience and opinion is that probably nothing happened during take-off with the brakes but rather the airctaft took off with the problem without knowing it maybe.? Just why should brakes fail when they are not used or applied ?? I meen probably no imputs were made to the brakes as for a normal take- off.just a thought
