HKG 25R/07L high speed exits

Did he discover that after using heavy braking in an attempt to make the high speed was just a bit too far and tried a sharp turn to get to it and discovered that he was facing the runway edge?

I was under the impression that it occurred at the end of the runway involving a mis-judged 180 requiring a three point turn

Something in the limitations saying not to back the Aircraft using reverse?

Worked for him...

but doesn't each AB setting give a constant deceleration independent of reverse selection (reverse, in 'normal' ops will just affect the brake temperature?).

The TOTAL rate of deceleration provided by the autobrake includes reverse selection. If you select full reverse, the autobrake works less hard to provide the required rate, hence the lower brake temps.

Looks like every runway end has available a simple 90 degree turnoff if you are at the end and no taxiways are closed or blocked.

Some aircraft are allowed idle reverse while taxiing. The limitation is no more than idle reverse. Perhaps he was light and just used that. Or does it specifically say no reverse movement of aircraft with engines at idle. Of course, backwards movement at idle is occurs during pushback all the time. Of course the engine is in forward thrust.

Backing the airplane with use of reverse thrust is prohibited.

Jammed stab. The engines are not selected into reverse when experiencing reverse movement during push back!

Not only is backing the aircraft using reverse thrust prohibited, it's also a very bad idea. Firstly, the increased FOD hazard is significant with all the crap being blown up into the intake and secondly, can you imagine the world of trouble you'd be in if you were backing up a bit fast and decided to use the brakes to slow it down? There are many other reasons but these two are enough for me.

What airport did this happen at?

I remember way back when in the '90s going through Atlanta which had Eastern Airlines as a major carrier at the time. Except for the A300, they did powerbacks from the gate with all their aircraft which surprisingly included the 757.

Looking at the HKG airport diagram, it does appear that there is a simple 90 degree turn off at the end of each runway.

Before someone provides a link to the mighty C130 or C17 backing up in dusty Afghanistan, I should add that my use of the expression "the aircraft" was used to denote the particular aircraft involved in the incident under discussion in this thread!

Eastern ceased ops in Jan 1990, Real Eastern March 1989. Powerbacks were approved for B727, DC9, and B757. A300 and L1011 were always pushed back.

So there ya go...it can be done as seen here. And apparently the CX one happened at YYZ.

What's more concerning is full reverse on a non-contaminated runway when brake temperatures are not an issue. Oh, and after an ACARS landing data assessment...

At the home base...

With one million feet of runway...

Idiots do this because they have no fuc*ing clue...

Moronic robots.
