Is Thrust Reverse Always Used?

Wed Oct 31, 2001 9:33 am

Sorry if this sounds stupid, but i'm only in high school and I don't go on enough flights to observe this, but when the approach airspeed is low enough, will the pilots sometimes refrain from using thrust reverse on landing. On FS2000, at times, it seems that i only need spoilers and minimal braking to stop. is this realistic? And I'm talking about on good sized aircraft, like the 737, 777, L-1011.



Thanks,
Aaron

Some aircraft don't have thrust reversers  Insane

Thrust reversers are almost always deployed on landing. In fact, I have never, to my knowledge, been on an airliner equipped with reversers that didn't deploy. Even at idle there is still a braking effect. A slight amount of throttle allows less brake use and the small amount of fuel used costs less than extra wear on the brakes.

At Bristol, those a/c fitted with thrust-reverse have to use it to avoid, running straigt off the end of the runway and down the hill!  Laugh out loud

I have seen quite a number of times that they did not use reversers at all upon braking but normally they go at least into idle reverse.

I fly KLM alot, and they always use the reverser.
But one time when we landed he did not deploy them, and he was really braking hard and using the whole R/W to slow down.
I was loadmaster on that A/C the other day, and talked to the mec. about it. And they had have problem with one of the reversers.
When in doubt, flat out!

Using thrust reverses is prohibited in some airports.
In Geneva-Cointrin for example,thrust reverses are
used only in extreme cases...it is for noise abatement.

Some airports prohibit the use of thrust reverses in
the night...22:00-06:00 for example!!!

Wudn't the brakes over-heat if reversers were not deployed? It would mean a really low landing speed aswell as a long runway!Imagine trying to stop a fully loaded 744 without reverse thrust!

They have land w/o reverse thrust (some airports have banned reverse-thrust). No airplane would ever be certified by the FAA if it required reverse thrust to land.

Well, last week I had my irst non-reverser landing at Heraklion on JMC 757. It was at night and HER is in residential area but im sure the revs werent used-its my favourite part, so I was pertty disappointed!

Im shocked, ive never seen a single airliner land without using reversers!

how would you like it if you had to fly into an african airport with a badly surfaced runway cuz the gov is too corrupt to find money for it, in an md-11 full of pax and cargo, and on top of that this part of africa is hot like all hell, on top of a hill and it just rained. oh yeah, i forgot there is a BIG crack on the threshold, so you have to move further down the runway to land. would you rely on your brakes then?

Thrust Reversers are a MUST in most ways.

The heavies needs thrust reversers to slow the plane down at touch down before turning off the runway to taxi-way.

I flew Delta 1732 from DFW-ORD(08/09/93) on a 737-200Adv., they used the thrust-reverser, I was behind the wing where I was seated.

Copenhagen banned use of reversers several years ago. The airport neighbors like it that way.

Reversers are always deployed, and engines are spooled up slightly above idle so the reversers can react faster in case something happens to the wheels or wheel brakes.

The reversers are mostly used for economic reasons. The little fuel used for a ten seconds reverser burst is peanuts compared to the wear on brakes and tires when not using reversers. But on a full size runway with fast exits it is really not a big issue.

The QF744 in BKK didn't use their thrust reversers.

I never use thrust reverse on my Cessna 172 when I land...

I thought the Bae-146 didn't have thrust reversers, just breaks

is this correct?

It's absolutely possible for a 737 to land without thrust reverse, and I'd be quite confident that any narrow body jet, and perhaps even some heavies can as well, it just depends on the situation.

There's lots of variables, but if you land for example with 11,000 feet of runway, a slight headwind, no one landing behind you, and land in the touchdown zone, the ground spoilers alone with get you slowed to 80 knots with plenty of room left, and that's just one of many many examples. It's our SOP to always go into thrust reverse, but in reality, we'd just barely go into it to have it armed, and mostly coast to a stop.

Thrust Reverse saves brake wear and in a hot climate, limit the brake temps. which is important for aircraft turnaround time, but it's also true the planes are certified to stop without T/R.

It depends on the aircraft.
I never flew or have seen a 744 land anywhere without reversers. However, I have been on quite a number of landings here in MUC on smaller planes (737,32S) without reversers, but only if the runways were dry. The runways are 13,123 ft each, and thus long enough for a reveser-less landing.
