CRJ Critical AOA

[BeechDawg]

Does anybody know the Critical Angle of attack for the CRJ?

when the nose drops...

 

[SELCAL checks]

At what flap setting?

 

[DrunkIrishman]

BeechDawg-

There is a chart in the AFM that shows critical angles in different configurations. There is no one critical angle like there is in say the C-172. Additionally, there is a low speed cue (stall snake) on the airpspeed tape that tells you that you are getting too close to the critical angle.

Not to Sure

I unfortunately do not fly the CRJ, and therefore do not have the AFM for the airplane. I am looking to leave my currnet company and I have been hearing that they are asking airplane specific questions in the interviews at those companys that fly CRJ's. Any information I can obtain will help. I appreciate it.

I don't understand why you would have to have intimate knowledge of a plane they are going to train you to fly if get hired. That seems odd.

Know the planes you have flown well. Understanding the plane you are going to fly inside and out is something I haven't heard of on the regional level. Although I'm far from the brightest bulb out there, so I may be wrong.

The critical AOA changes?

Can you go into a little more detail on that?

 

[labbats]

He probably means it changes with flaps/slat configuration.

 

[Dizel8]

Well then it should be different for the C-172 as well, the darn thing has flaps.

Looking forward to this discussion

 

[Nindiri]

I'm not aware of config changes ever causing a change in critical AOA, but I'll be the first to admit that there's a lot of stuff I don't know.

 

[146guy]

The critical AOA does change with flaps. The important thing about flaps is it allows the lift coefficient to increase beyond its maximum in the unflapped condition. Max lift coefficient is reached at the stall angle. With flaps down and all things being equal the stall will occur at a lower angle, but the lift coefficient is much higher.

 

[Nindiri]

Okay, I see what you're saying. By changing the chord line, you're increasing the AOA.

Seriously: Who Cares??

 

[BeechDawg]

I know some of you think that knowing this information is frivilous and a waste of time, but I'd like to know. I understand that AOA changes with configuration changes, but I'm not sure what the interview people are looking for. (Exact numbers or knowledge of the subject matter) I would like to be able to show whomever I interview with that I tried to get the information they desire. I appreciate all of the people here and I value most of the information and enjoy the opinions of some. Hopefully we can all help each other. Does anybody know where, if anywhere, I can find the info on AOA of a CRJ

WTF???

"Well, Mr. Anderson, we could ask you about the 1900 you've been flying, but that would be too fair. Why don't you tell us how the hydraulic system works on the A-380?"

Any company that asks you tech questions about a plane you've never flown is not a company you want to work for.

 

[bitememesa]

He's probably been looking at aviationinterviews.com gounge of Mesa interviews where they ask the 300 hour wonders what the Critical AOA on the wing is...this will obviously make them safer, more efficient pilots because knowing the Critical AoA will prevent them from severely bending an airplane...

It's the latest question on the Pinnacle interview test...

So me wanting to prepare myself for my future is now a bad thing. Showing initiative and trying to better my future turns me into someone that doesn't deserve to leave my current company for something better. And with what I fly now, I guess all I can do is improve.

Pinnacle is starting to get into the CRJ, and I just would like to be prepared if I choose to send out a resume. The percentages are pretty high that I could end up in a CRJ at some point in my career, so why not get a head start.

 

[FlyChicaga]

I guess if they are asking questions like that at the interview then they will find themselves with classes full of All ATPs and Regional Airline Academy students. Maybe some from Riddle as well. Which I thought was exactly what they were trying to get away from with Gulfstream.

If I was asked that for the ERJ, I'd say, "When the pitch limit indicator says so."
