I just can't believe what I am reading here.... all those so called 'experts'.....
1. Thrust reverse is the most effective at high speeds, just after touchdown.
2. The deceleration effect of thrust reverse is far less than the brakes.
3. Modern Carbon Brakes will never "overheat" or burn.
They might get hot during a landing..... . The only case where they could overheat is during a high speed abort, but they are all certified so that no fire starts 5 min after the rejected take-off.
4. Ground spoilers cause a small amount of deceleration but their main purspose is to brake the lift, and put the aircrafts weight on the wheels so that the wheel-braking is very effective.
Some operational facts:
1. Thrust reverse is seldom used on bussy European airports which are almost all noise sensitive. We use 'IDLE' reverse in those cases. Idle reverse makes almost not more noise than an engine turing at idle.
Sometimes when safety requires it, more than idle is used, it is NEVER forbidden to use reverse for safety reasons. ( An aircraft that exits the runway makes far more noise than using reverse)
2. Charter operators use in generaly more reverse than others.... they operate to holiday destinations which are in generally not noise sensitive at all. It is more economic to use the reverse than to use the brakes for deceleration, the price of the brakes is far superior to the price of the extra kgs of fuel you use with the use of reverse.
3. In practise long runways: 'During the initial touchdown mostly idle reverse is used, or a bit more,.... once the aircraft is slowing down below 100kts, we use the wheelbrakes, and stow the reverse to idle....'
Very short runways: Full reverse, and autobrakes on medium, or full manual brakes.
I hope we cleared some things out here!!
