RAH is no longer a regional so that just leaves Compass.:D

Now with the help of Frontier, Midwest, and our own pilots, lets strive for a great contract flying the 170/190.

Oh, if you use CON for cruise flight, you are too high. Do not use it unless single engine

if you are flying in cruise with the LIM on you will also have the eyebrows up...you might be to high for cruise.

If you are increasing speed once you level off the CLIMB 1 will be enough to get the LIM to go away

From an outsider:

1) Does doing this raise your ITTs?
2) How much of a speed difference are we talking about?


If the answer is "yes" and "less than thirty knots," it probably isn't worth it.

1. It depends on what setting you're already in and in what phase of flight. But most likely, YES.

2. Kinda a vauge question. But I think people were using this setting to climb faster at a set speed. Or using it to get to cruise speed faster when leveling off. I wouldn't recommend it.


There is a reason for 2 different settings. CON is for max continuous. CRZ is for cruise. If they were interchangeable, then there wouldn't be 2 settings. Fly by the book. The only time we call for CON is in a single engine operation.

Useless response.

Why would you want to cruise at a speed that requires CON power anyway? What's the rush, unless it is the last leg? Plus, I've never had a problem cruising at Mach .81, so I don't see a reason why CON would ever get used in normal ops.

DING DING DING DING DING........

Somebody gets it.....

My company's SOPs have normal cruise limited to M.78 or less, for improved fuel economy and less wear and tear. Economy cruise is usually slower than that, depending on cruise alt, weight, etc. CON should be used only in emergency situations...that is its sole purpose. It is normal for us to see LIM briefly upon level off at cruise, but just for a few moments as the speed catches up. Hope this helps:)

To add to this...LIM appears when the actual speed is 5 kts or more less than the set speed in a climb (or greater than 5 kts in a descent). As you said, LIM only functions in FPA or VS, and so if it appears, the selected FPA pitch angle or VS climb rate is more than the engines can provide. The first thing that comes to mind for me is Pinnacle...why ask for a climb rate or pitch angle that results in a deteriorating airspeed? If level and the aircraft won't accelerate to or hold the selected speed, then the pilot needs to rethink the situation.

CON is an emergency power setting only according to Embraer. If someone is selecting CON to solve a cruise or climb speed issue, I suggest they refer to the performance manual for gross weight limitations.

I don't think "LIM" on the FMA qualifies as and "emergency situation".
