Thrust Reversers out while taxiing???

It used to be acceptable at SkyWest, but is now prohibited to deploy them during taxi. I believe it was due to contamination issues but has now worked its way into ALL conditions.
 
What's the deal with no deployment on landing? I've ridden in the back of some of these POS ERJ, and they don't even pop 'em. What's the deal?

how did you see them pop from the inside?

we pop 'em just dont use thrust to slow down unless we need it. the buckets open slow us down enough

From what I understand there are several different "grades" of reversers available on the jungle jet. The lower end were not made to withstand max reverse multiple times per day. It's also my understanding that most thrust settings in between idle and max while in reverse produce large levels of vibration that have been known to cause stress cracking on the reverser mechanism.

Plus not using reverse with carbon brakes actually increases the life of the brake. The hotter they are the harder they become. So, not using reverse causes higher brake temperatures prolonging the life of the disc.

This is all what I've been told so I could be completely off. Someone feel free to chime in.

The POS ERJs have different brakes then other airliners. You don't need TRs. Some ERJs don't even have TRs. That's why when you're riding on ERJ, the braking during landing is sudden and it will make some pax scream. It's standard procedure...

flight safety taught to alternate thrust reverer deployment during taxi in the beech jet. It kept the taxi nice and slow...

Not that anyone taxis an RJ slow

Are you sure it's the braking, and not the actual landing (touchdown) itself? :D

What's up with the CHQ crj's in IAH taxiing with TR's deployed? Is that not against company op's?

Didn't you get the memo? TR's deployed is just a sly way to "flip-off" other crews. You can't actually give the "finger" incase a passenger sees you, so you deploy the TR's as a sign. CHQ pilots must not like you. That's all.

I would like to know if this is true. If it is, it was pushed of the drawing board way too fast, IMHO

They probably think they are flying the E170, I hear that thing has more power than any other airline pilot can handle.

Only the quatauquian could harness the awesome power...
 
At Air Wiskey we had to have the reversers stowed below a certain speed - it's been a while so I don't recall exactly - I believe it was 60 knots. They told us it was because the angle at which the reversers deflect the air can kick up debris into the inlet below that speed. They even showed several examples in class. Oh and idle reverse only on dry runways longer than 6500 feet.

It's a tool to be used. Why would they ever be on the airplane if they weren't to be used at all. I usually deploy the buckets but don't spool unless it's wet, slippery, short runway, etc. No need to waste the fuel and decel quicker on a 10000 foot runway unless someone is close in behind and you need to get off at a certain taxiway.
 
I saw a CHQ CRJ pulling up to the gate with the left TR deployed and then stowed it just as they were pulling to a stop.

That seems like a bit of a distraction at that point and not very necessary. I mean, are the brakes going to overheat because you use them to stop at the gate?? Whatever, I don't really care anyway...

Snapping a lever back down is a distraction? I wouldn't think any more so than increasing thrust a little if you're too slow pulling into the gate.
 
XJT and CAL use idle reverse. You dont even hear the bucket come out or the engine go into reverse. We use brakes. It save the company money on fuel and engine maintenance. But if you had to use full reverse go right ahead, nothing prohibiting you from doing so.

I've heard Eagle inhibits their use to save fuel, fewer T/R write-ups, and less brake wear. Use is prohibited on dry runways greater than 7000'; Idle may be used on RWYs less than 7000' or BA reported as "Good"; Max used on BA reported "Fair or Poor" or for performance reasons.

It depends on the aircraft. Some are authorized for backing up the aircraft even. I've seen many a C-17 do this.

I think some people do it so they aren't riding the brakes on the taxi, others just like to fiddle with things.

I'd classify myself as a "fiddler" too.....I like to go into Beta, out of Beta, into Beta, out of Beta, etc when im taxiing......I'm just an exciting person in general, and that rubs off on my lever movements in the cockpit. :D

The reversers themselves are not inhibited, but we're not supposed to use them unless the situation is as posted above. Another situation would be in the case of aborted takeoff or we feel we're about to leave the runway.
