E-170 vs E-190 systems
 

Howdy
For those of you flying or have flown the 170/190, how much systems commonality exist between the 2? Will pre-studying for the 190 when assigned the 170 or vice versa be a help or a hindrance?
thanks!

no everything you need to know are the same, differences are engines, wing and a couple other things. Where you going?

Different engines, wings and obviously different dimensions and weights. The E190 also includes tail strike protection which limits your AOA in the flare. Other than that it's the same aircraft with much better climb performance. It's climbs like a rocket compared to the E170 even when heavy. Systems are exactly the same. If you're going to Republic make sure you have the A/C limitations including A/C weights committed to memory and you have the automation down packed with a full understanding of the VNAV functions.

Your main course of study will be the EMB 170-100/200 followed by a Power-Point slide differences course that discuss the different engines, wts., dimensions, over the wing emergency escape exits including the associated escape lighting, and the tail strike protection. A/C limitation between the two are different too.

Thanks......!

I'm curious how crj700 climb performance compares to the E-170?

Very comparable.

80 percent commonality in parts

Why not just wait and actually study the material from your airline that pertains to the airplane you will be flying?

because maybe I won't be flying for an airline, and maybe I will need to know it better than the average line pilot, maybe I will be qualified in both, and maybe I would like a head start instead of drinking from a firehose. But this isn't about me. Trust me, I've been though this before and know what I am doing ;)

Can you explain this?

The "Tail Strike Avoidance" is a fly-by-wire function for takeoff and landing flaps 5 or 6. During landing, it measures the height above ground level measured at the mains using two RA's to limit the pitch in the up direction by restricting the control column authority and for takeoff it uses vertical speed. The system is engaged within 20ft for T/O and 70ft and below for landing.

Thanks....

Let FlightSafety do their thang man...try not to let your liver get destroyed in the process of cramming a 7 day training course into 14+.

This. If you can show up with limitations and memory items down you're ahead of the game. Don't worry about what or why they are, that will come when you get in class, just know them. If you have the chance to start learning flows from the SOP's as well, that will be beneficial. Again, just go for rote - don't worry about why you're doing things, again that will fall into place as you learn the systems. One of the issues I see with people is they don't take time to study for the sim because they're so worried about the oral, if you can get the rote items down ahead of time, you can then build those to higher levels of learning as you go through systems class and SIT/GFS _and_ show up prepared for sim.

Here is a study guide

I once jump seated on a RAH 175 and was talking to the capt about the airplane. He said RAH doesn't test it's pilots on weight limitations in the oral because the only way for you to get performance numbers is through ACARS and the system won't let you exceed any of the limits. I found this strange as we use aerodata/acars on our CRJs as well but still have to know limitations.

The guy above you bumped a really old thread. He also bumped a post from 2007. It's spam!

In all seriousness though, you don't have to memorize numbers that are listed on our release. An E170/190 rated pilot could end up having to memorize a ton of different numbers that are really wasted time since they are all available on the release paperwork. To illustrate why... between the various E170/175/190s in the fleet, there are at least 4 different max zero fuel weights used, 3 different max takeoff weights, and 3 different landing weights. What would be the scenario where you would need to have any of those numbers memorized for the safe conduct of the flight? The release includes things like BOW, MZFW, and all planned/max weights. The only things you need to memorize is max ramp weight since it's not listed on the release.

Our program here is focusing more on memorizing things that MUST be accomplished from memory for the safe conduct of the flight. E.G. flap speeds, gear speeds, getting your O2 mask on. For everything else, there is little reason for rote memorization.

Makes sense. At Endeavor, we aren't dual qualed on the CR2 and CR9 so the weights we have to know are just for one or the other. The 900, and I assume the E170/175 aren't really weight critical in most situations either. However, they do quiz us on those items in the oral but it's not a big deal to memorize them.

Not that it matters, but I've never been in an oral at Republic that didn't include weight limitations.

Did I move up a number?

You were told wrong, I was required to know all limitations for my oral....including weights for both the 170 and 175.

On the S5 side we just had to know MLW.

Who was your check airman? I'm on YX and haven't been asked specific weights in at least 4-6 years.

E-170 vs E-190 systems
 

I only got asked a couple during the oral but was told all through training to make sure we knew them all because they were fair game. The also told us we were subject to know the 190 numbers if we were going to ACY. Not saying things haven't changed, but my point was I made sure I knew them all, as instructed by FSI.

Quoted directly from the Republic Airlines AQP ERJ-170/175/190 oral question bank, downloadable from Obey 365....

"Weights and other numbers that can be read off the release or a placard are not required to be memorized."

If it was M.M., I can believe it...

Did my ATP with him last year WITH FAA sitting in. Limitations found on the release are not required.

That's fine and dandy. My statement stands. Any cka can ask whatever they want in an oral, regardless of what you find in obey. I've had them every year.
