If there's a long runway, it's not high traffic hour, and the 777 you're on doesn't need to vacate the runway early, chances are they won't use reversers. Like the replies above, the 777 has very effective carbon brakes. I remember the first time I flew on the 777, landing in ORD
several years ago, I was so surprised that landing on 22R we never utilized thrust reversing.
My last 2 trips in June, on legs flown with the 777 we used thrust reversers once. On my ORD
on UA137, that leg we flew an international equipped 777 and I was seated in 1J in F/C. Upon landing on 28R I could hear only slightly the wind noise from the cascades opening up. Sometimes it is less obvious if you're sitting up front ahead of the engines.
Last leg to HNL
on UA61 which arrived around 4pm, we landed on 4R, not commonplace as usually before 630p, the majority of heavy jet traffic lands on 8L
. Anyways on 4R the normal practice is to roll down to the end and then do a turnoff, which we did without reversers deployed. Still with 9000' of runway we were out of autobraking and coasting before we crossed 8L
, so we easily slowed down even with a full load of passengers. I had to sit near the engine at 22J
and even idle reverse wasn't used.
