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.

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.
people are odd, fascinating, and oddly fascinating.

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.

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!

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?

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.

Always keep your number of landings equal to your number of take-offs

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.
