Emirates Airbus A380 at MAD

[antiguogrumete]

It is always a spectacle to see the Emirates A380, although not in the best condition ...

love this plane

I find it odd that the inboard TRs were the only ones deployed. I wonder if the outboard engines are equipped with TRs or if it's a technique/procedure to only use the inboards.

I just googled... same in this video. I bet they only have inboard TRs

Edit: More googling...

The A380 was initially planned without thrust reversers, incorporating sufficient braking capacity to do without them.[127] However Airbus elected to equip the two inboard engines with thrust reversers in a late stage of development helping the brakes when the runway is slippery. The two outboard engines do not have reversers, reducing the amount of debris stirred up during landing. The A380 has electrically actuated thrust reversers, giving them better reliability than their pneumatic or hydraulic equivalents, in addition to saving weight.

Yep, just "innies". First one that we had land at LAX, I was on the airfield to watch (perk)

Only the inners deployed and I thought I was going to see something ugly. Now they're so common I don't pay attention - unless I'm on a service road when they taxi. PITA to "follow"

Id think if there was some sort of disymmetry with the outboards, there would be a large moment and off in the weeds we go.

Relying on just the brakes would be pretty bold to slow down that much Ke.

Flown on the Dugong a couple of times as passenger. It's a great ride and very quiet. Not too good to look at, though. Although, it wouldn't take much - just make the nose cone a little pointier and it would help a lot with the looks. The proposed stretched 900-version would also make it look a little sleeker.

Airbus logic for not putting reversers on the outboards were for fod control, not a dissymmetry problem.

Landing distance computations are done without reverse thrust factored in. Landing speeds aren't very different from other jets, the wings have spoilers and ground spoilers to dump lift, plus a very effective anti skid system.

So while reverse thrust is handy, it's really not that necessary.
