American Eagle Reverse Thrust Question

Mon May 24, 2004 2:38 am

I was out at CMH this afternoon for a little while and watched 4 American Eagle ERJs come in on 28R (8000') and not one used reverse thrust. Chautauqua ERJs and a Comair CRJ all used it.


Is there a policy to save fuel and engine wear like Qantas used to (does?) have? Or would 8000' be fairly sufficient to warrant just braking?

I'd think anything over 6000 ft would be sufficent to not warrent the use of thrust reversers. Just a guess though.

Anyone else?

IIRC, not all ERJs have reverse thrust, i believe its an option, this could explain it as well.

It's very possible that they did not need it, and if they did not, that's a lot of wear on the engine they don't need to put on. I don't know if all American Eagle's ERJ's have reverse thrust capabilities, but the ones I've seen all did have it. But it's very possible some of them don't, especially the older ones.  Big thumbs up

While on the topic of the ERJ-s ...

Why does it always look like they have more of a nose down attitude on approach? I noticed it at MCO when there was a simultaneous approach between a 737 and an ERJ. THe ERJ looked like it was fighting to get lower while the 737 was just gliding down.

This is one of those questions that gets beat to death here on A.net. When landing you don't always need to use the T/R's. Their use is based on serveral things including: a/c weight and braking conditions. Also, the Carbon Brakes on the ERJ offer fantastic braking with little wear and Carbon brakes actually work better when they get hot.

OOh, and was the flight A/E or A/C...?? Several of the American Connection aircraft flown by Trans States do not even have T/R's installed on the aircraft.

They were all Eagle. I'm just curious why the Chautauqua ERJs needed it but not one of the Eagles did.

Aircraft like the CRJ, ERJ, and even the DC-9-10 do not have leading edge slats, thus they have a nose-down approach while decending to the runway.

To help reduce the maintainance on the thrust reverser and TR actuators. Eagles policy with the Embraers is that TR is only used on runways less than 7000 Ft. and/or if the situation dictates it. i.e. slush, rain, snow or some other contamination in the runway. Also all the ERJs have carbon brakes and carbon brakes like to operate at a higher temp than steel, thus causing less wear on the brakes. Brakes are cheaper to change and repair that TRs.

Also all Eagle ERJs have TRs on them.

That's what I was wondering about. Thank you for the response.

I would not use Reverse Thurst in an ERJ with lets say just 7,000 Ft. Plenty of room just to use the brakes
