autobraking system in crj200 and erj145?

Wed Mar 15, 2017 3:56 pm

Anybody knows it the crj200 and erj145 have an autobraking system?

Neither of them have an auto brake system, however both have anti-lock and anti-skid protections.

What about trust reverers?Only the crj200?

I cant think of any airliner without thrust reversers. Even turboprops have them.

The BAE146/Avro RJ series do not have thrust reverse.

Also, turbo-prop reverse isn't quite like turbo-fan reverse. A t-prop will physically change the angle of the blade to push air forward, the turbo-fan will redirect air through blocker doors of some sort, with no changes to blade angles of the fan.

Many EMB-145 aircraft don't have thrust reversers, it's an option on that plane. We had them on all our planes at Eagle (Envoy) but were very restricted by the company as to when we could use them.

It doesn't mean its not reverse. It does the same thing. You can make a turboprop roll backwards if you hit them from a stop.

The BAE 146 is not equipped with thrust reverse although they are rare outside of Europe.

Some of the Trans States E145's do not have thrust reversers.

Just curious, let's say you land and you use thrust reverser on a particular plane or flight that you were not supposed to. Does the company know this? Do you have to submit paper work or something?

Right, but we are talking about reverse thrust, which is different than what t-props have. It's actually not the same. Since you're nitpicking, I'll return the favor. T-props don't produce thrust in the same way turbofans do, so they don't have reverse thrust. The mechanical intracacies are very different between the two, which provide the different ways to reduce speed.

Simple answer: With few exceptions, it's standard practice to use them if equipped, so a pilot wouldn't have to self disclose a normal practice.

Damn iPhone. Somehow part of my sentence disappeared. I fixed the original post. What should have been there was "turboprops don't produce thrust in the same way turbofans do." The point remains, it's not called reverse thrust on a tprop and getting the reverse effect happens differently. That's all I'm saying, in direct response to your incorrect assertion that all planes have reverse thrust, "even turbo props."

Its also for more payload that not all embraer have reverse thrust.

There is a previous thread on the Embraer ERJ 135/140/145 Thrust Reversers .

viewtopic.php?f=5&t=741063

Lots of good info, particulary weight (some 700lbs), noise restriction issues, etc..

Fokker F28 didn't have them either.

No disclosure and some guys did use them every leg. It was a long-winded company limitation that aimed to reduce maintenance, fuel burn and cabin noise. There wasn't really anything punitive unless there happened to be a fed or check airman onboard or something like that. I always thought it was silly to not use them but it was in the book so most only used them sparingly.

Not all of the birds had FOQA, but on the FOQA birds the plane would record all the parameters, and when downloaded the company could tell if thrust reversers were used or not.
No paperwork is required, though I noticed that when I used thrust reversers, I tended to get thrust reverser faults stowing them more often than not, so we ended up getting stuck at an outstation or leaving a bird with a writeup at the hub.

You learn all sorts of bad habits flying an Embraer-145 that you have to unlearn when going to another airplane like Boeing/Airbus/Bombardier
(1) Bypass safety guards to do normal operations (start engines)
(2) Not use thrust reversers
(3) Not check outside air temp when flying through clouds/visible moisture
(4) Ignoring master cautions

How come master cautions were ignored?

The anti-icing system was completely automatic, even engine anti-ice, so people get in the habit of never paying attention because the plane took care of it. There was that caveat that if you noticed ice accretion and the system hadn't turned on yet, it was the pilot's responsibility, but that was rarely the case because the system was good about taking care of it. Looking back on it, it's a goofy airplane for sure.
