All about the CRJ

[Crossky]

Adding the FF's at cruise nails the airspeed issue..e.g 280 kts, 1400 lbs/side.

Take your landing weight speed card drop the last 3 zeros and add 20, that will be an approx N1 setting (47000 ---> 47 + 20 to get 67% N1 fully configired at the marker.

Going to pitch mode before adding flaps or pulling one notch of spoilers helps that pitch ballooning from the flaps deploying

Disconnnecting the a/p by using the trim makes the disconnect sometimes smoother

We're taught to set 80-85% N2 configured on approach. N2 because below 79.1% N1 the engine speed control syncs N2, not N1.

Even in pitch mode the autotrim will occur when selecting flaps, won't it? Selecting flaps below 200 and/or hand flying with flaps extention above 200 is better.

Disconnecting the A/P using the pitch trim switch disconnects both yaw dampers as well. Do you really want to do that? The A/P disconnect bar on the flight guidance panel is nice, try it.

Yes, but thats not the point. Think about it. If you are in VS mode and you put out flaps the aircraft is going to have to change it's pitch to keep the same VS due to the configuration change hence the diving movement you tend to get. If you are in pitch mode the aircraft isn't going to do anything except trim to hold the pitch which is mostly not noticeable to the people in the back.

Never happened to me. And why would you reach all the way up to the panel to dump George when there is a really nice red button right by your thumb that does the same thing?

When you do raw data t/o's push the runway update key on the lower left corner of the FMS; no FD. You get the runway update w/o pushing the TOGA button.

 

[JetPilot_Mike]

200

If at 320-330 kts at 11,000, and descending below 10,000, go to Idle, select 1,000fpm down, and add 4 clicks (ie 1/2) of the spoilers and you'll be at 250KIAS at 10,000.

Yes, at 70kts don't slam the TR's closed!

You make a good point about pitch mode, I'll try it next trip, it'll be the something new I learn.

I'll discon the A/P using the pitch trim switch also, NOT the red A/P disconn/stick pusher switch, and see if the YD's stay engaged. See the original pposter mentioned the pitch trim SW not the red button aforementioned.

My new contribution: Steep ATC assigned A/S descents in the terminal area are much easier actually using DES mode while hand flying than guesing and dialing or syncing V/S rates.

Also, JMO: Flight spoilers are not in good style unless absolutely needed (descent w/anti ice), way behind in crossing restriction (put down the USA Today): they vibrate the airframe, waste fuel, and bug the pax. If fast and/or high near the OM drop the gear first, it's gotta come down anyway right? And if near flap speed with gear up drop the flaps instead of spoilers, same deal.

I do like it that we can use them in conjunction with flaps (unlike the mag dog).

 

[Crossky]

er, mad dog.

 

[Tram]

Good thread guys..

Thanks..

 

[flyguy75000]

No, the TURB button is the turbo boost button. It makes the plane actually climb above 15,000.

I think it just slows the response time to correct the FD. As if the FD isn't slow enough already. TURB does do a nice job with damping out some of the oscillations when climbing in speed mode though. It's a shame you can't use it when on the glideslope.

'Bout time the truth came out.

Let's hear your tips/techniques/tricks to everyday flying on the CRJ200/700/900. While we're at it, include any common emergencies, flaws, or "interesting" experience. Anything from pitch and power settings to smoke in the cockpit.

At the risk of looking like a lame topic, I think it would be very valuable to have an educational thread, since we have a lot of low time new hires out there - plus, I am due to arrive home from an overseas deployment (flying a different aircraft) and I'd like to brush up on some stuff other than the books...

Fly safe!

Nice to see you on line again bud..

Here is my piece of advise, especially now that I'm flying an MD-11..

I recall way back when we first got RJ's at ASA, we got a DAL L1011 J/S rider and on short final he all but panicked that we were going to slam the airplane onto the runway because we weren't flaring.. his worse were something like "You're not flaring!" while he was holding for dear life onto that backs of the seat!

Anyway, after we landed, we explained to him that this is the normal deck angle of the CRJ, mainly due to no slats on the wings, and also due to the angle of incidence of the Challenger wing design. In our case, the CA and I were both not disturbed by his panic, but I could see where that might jar a new FO or a edgy captain to get upset if his J/S rider started to freak out.

So from that point on, I always made it a point to brief guys who's never ridden in the front what to expect for a sight picture on landings.

I'm sure by now (8 years later) most of the regular J/S riders are familiar, but back then the CRJ was much more rare, and ASA's J/S was newly opened so it happened more than once.

Send me a PM sometime and let me know how the new gig is going! Hope all is well!

Thanks for the responses! Keep em coming!!!

Disconnecting the A/P using the pitch trim switch disconnects both yaw dampers as well.

Not in my experience, it doesn't.

 

[Hovernut]

What is the circle around the Alt Static Port mean?
WHat does the circle around the Stby Pitot Probe and TAT mean?

These are the only ones that have the red or white painted circle around them.

What is Potasium Superoxide? Do we have it on the CRJ? If so, how long is it good for?

What the heck is ADSHC?

Fun Stuff!

Hey Gunny,

Potassium Superoxide (KO2) is what's inside the O2 canisters for the PAX oxy masks. Each PSU has one Skoal-sized can. When they pull on the mask, a string pulls a pin and a striker snaps in the can and lights the oxygen 'candle.' That's why they get hot when producing O2 and last a finite amount of time. We used KO2 canisters in our firefighting breathing equipment aboard Navy ships and subs; they were supposed to last 30 minutes.

TRIM!!!
Sounds like some confusion on the A/P disconnect with the trim subject. The easiest way is to move the nose up/down trim rocker with your thumb as you do while hand-flying...usually trimming a little NU during the disconnect since the AP usually kicks off ND. Works like a charm! Don't use the little red button with your index finger 'cause as said before, it'll kill both the trim (bad idea) and the yaw damps!

I agree with the convention of using the spoilers as a last resort. Gotta do it in the winter to keep the a/ice going, but unless ATC or you $crew yourself on a descent/xing, proper planning should suffice. Now, if you get the short approach...all bets are off! 3k down with the boards out and flaps 20 will get you down and slow in a jiffy to fly to the numbers! Drop the gear and you'll rival the shuttle!!

Nothing like driving slow in the pattern, just above min clean, sippin' the fuel and seeing the other guy chomping at the bit to drop the flaps

 

[acaTerry]

Faults? Putting 50 seats in it....

I agree with you. The flight spoilers handle is the "mistake lever" to me. Either I mess up, or ATC did. I don't like to use them at all.

Our training department has told us that the yellow caution messages, as well as the N2 arcs associated with anti-ice are advisory only. You're still getting ice protection even with the cass messages.

Keep those N1 values synced perfectly. It's horrible to ride in the back row if they're out of sync. The rear of the fuselage vibrates. Even .1% is noticeable.

On some of our aircraft the Cabin Alt will actually climb if you reduce the power to idle. When I'm descending and/or slowing down I keep the ECS page up to make sure air is getting to the packs. I don't like my ears popping. If I have to I'll use the spoilers with the engines spooled up enough to keep airflow to the packs. Or see what the Capt thinks about starting the APU.

I'm going to try the speed mode with TURB selected in a climb tomorrow, as well as bumping the thrust levers up a tad to delay the GLD.

This is one of my pet peeves... it needs to be written up. Nothing is more annoying than seeing a 1500 fpm gain in the cabin after you wipe the power.

Yea, or have the same thing happen when the cabin door opens, after setting the landing field elevation correctly.

Also,

Hitting the trim switch while the auto pilot on shouldn't kick the YDs off. Hitting the "sync" button the on the back of the yoke shouldn't do anything when the AP is on. For the airplanes we have, I wonder if there is a difference with different serial numbers.

I use the little red button with my thumb all the time... I've never had the YD's to disengage by using this button. Works like a charm.
Now if you use the little button on top/back side just behind the trim switch, this is the "Press, Hold, Release" button that does disengage the Stab/Mach Trim. But it doesn't disengage the YD's either.

especially if you side load it a bit.

I'm a little confused on this. Do you add rudder or rudder and aileron?

The RJ flies fast? I must have flown an older version then..

 

[DrewBlows]

It means "within this circle lies the alternate static port".

WHat does the circle around the Stby Pitot Probe and TAT mean?

"Within these circles lie the Standby Pitot Probe and TAT".

 

[n757st]

I'm a little confused on this. Do you add rudder or rudder and aileron?

Sometimes, especially when the airplane is floating a bit, I just throw a tiny bit of aileron in, it will touch down on one wheel, delay the ground lift dump by a second or so, and gently eases on apposed to especially when you are light and you barley touch both mains at the same time, which activates the GLD and slams the airplane on.

Ok thanks makes sense. I was thinking you were adding rudder.

 

["GO AROUND"]

This isn't CRJ specific but, I have been flying with a bunch of new FO's and they were not told about the shoulder harness only release on top of the buckle. It is kinda funny watching them twist the release and reattach the lap and ball buster harnesses.

When transitioning from 250 to 290 in the climb with the autopilot in speed mode, just rool the VS wheel down and the mode will switch to pitch mode withput pushing any buttons. If you do it slowly it makes for a quick and smooth transition.

 

[nethan]

Yeah, I was never told about the shoulder strap release. After being on line for about 2 months some captain took pity on me (after laughing all the way up to the flight levels) and told me about the quick release.

 

[CheeseDick]

bump...

The white circles around the static ports are used to identify RVSM critical areas. Any missing paints, dents, etc can lead to RVSM errors. I think the emergency exits are supposed to be bordered in white as well.

It's been awhile since I wrote the RVSM manual

ADHSC = Air Data Sensor Heater Controllers. turns the probes and sensor heat on regardless of probe selection. If probes are off, they get turned on one weight is off wheels.

 

[the turtle]

New FO's who come in hot and we ride the flare half way down the runway...CA's just grab full speedbrake and it drops right down!

I remember doing that a few times... not SOP, but it saved your a$$.
