A380 reverse thrust

Hi there.

Did anyone notice the 2 outer engines reverse thrusters were not deployed during the A380s landing at Heathrow yesterday ?

Could this simply be a safety measure being as the outer engines hang out over the grass ( to avoid ingesting debris ) or will this be a common feature.

Also does anyone think that the A380 may well taxi on its 2 inboard engines on narrow taxiways.

regards

…Reverse thrust isnt taken into account in stopping distances?

In modern aircraft take off performance is usually more restrictive than landing performance on the same runway. Under JAR-OPS reversers are all considered to be inoperative for take-offs on dry or damp runways. They are allowed to be considered serviceable on wet runways but as so few aircraft these days need the preformance they are generally considered inop in order to standardise take off calculations.

…but not primarily for the reason he gives.

Weight saving?

Ceramic brakes…more efficient at slowing things down…and lighter too!

As PaulC has said, the WhaleJet has only got reversers on #2 and #3 engines

There’s a very brief discussion of this very subject here 🙂

Nordjet,

the A380 only has thrust reversers on the inboards because of the risk of ingesting something.
