Default Slow climb?

You have just taken off from KBOS for a max endurance flight to KSJC. You are planned to arrive at your destination with legal reserves of fuel, plus a few extra pounds. In order for your fuel planning to work, you must fly at or above FL430. Your flight planning has you at cruise altitude within :40 min of departure from KBOS.

Your typical climb rate is 4000 fpm initially and 1500 fpm til the top of the climb. However, soon after takeoff, ATC places you behind several CRJs climbing at 500 fpm to FL350. You will now not be at FL430 nowhere near :40.

You also haven't eaten in 7hours, your crew food is in the cabinet, and you can't eat with the O2 mask on. You are climbing in wx, with moderate chop until you reach cruise altitude.

Thats funny that you threw that in there about RJs and 500FPM, you dont miss an oppurtunity do ya!

If this were me, and plug it into the FMS and compare the info based on FL430 cruise and the new altitude. If it look ugly then maybe plug in LRC and look to see if that makes a prettier number. In any event im required to call dispatch in a situation such as this and it will be somewhat of a joint decision on what to do from there.

I'll probably catch some slack for this, but I'm also in the school of thought that 500 fpm to cruise altitude ought to be reason enough to keep that aircraft in the lower flight levels until everyone else with better performance has climb to cruise.

I wish Bombardier had installed beefier engines on the CRJ's so they could climb.

I jumpseated home from Berlin with a Bombardier design engineer. He explained that the big problem was not the engines but the wing. The CRJ has the same wing as the Challenger, which he called a "cruise wing" - good for long haul fuel economy. He said in afterthought that there is no way that should have been put on a "regional jet."

Supposedly the 700 and 900 were to have a "climb wing." I got out of the rat race before I found out.

It just depends. For us, if ISA is + our climb can slow down to less than 1000 fpm in the upper 30's enroute to the low 40's. I rationalize that if I'm climbing slower it's a good chance others are also, and also by the time my climb slows down I'm usually above most other's cruise altitudes. Even with the reduced performance I can still steam up to .80+ once level. Temp at altitude really effects our performance.

I'd keep going. You've got a reserve just for this reason. Of course, keep an eye on your fuel and maybe tell ATC that you need to climb for better fuel rates.

Not exactly. At least not in my opinion. This is an assumption, but I bet the FAA would probably want the pilot to arrive at the airport with bare minimum IFR reserves unless there was an emergency situation.

You mean the FAA doesn't subscribe to "if the minimums weren't good enough, they wouldn't be the minimums" theory?

All I know is that if I was PIC, I'd do what I had to do in order to land at my destination with no less than minimum IFR reserves. If that meant telling ATC that we'd have to land short if we stay at the altitude for another 15 to 20 minutes, so be it.

I know a guy that did a diversion into another airport because if he held until the EFC time, which they were rapidly approaching, they'd land at their original destination with less than minimum IFR reserves.

If you bring in a dry aircraft, "that's what the reserves are for" isn't going to cut it with the inspector.

Agree. I'm pretty conservative when it comes to fuel (aside from combat, when that was the first time I'd seen both fuel-low lights on at the same time while in hard IMC feeling for the tanker). Fuel is just one of those things you don't mess with. And the reserve isn't there for "a little extra"; it's there for a legitimate bind such as an emergency, not as a stretch to normal ops.

You think people would learn from Avianca 052 in Cove Neck, New York, the danger of cutting into reserves (among other problems with that flight).

But people still stretch fuel.

Hi everyone- I'm pretty new here and have only posted in the ATP forum since I plan to go there... I just got my PPL yesterday. I do enjoy flying jets on flightsim, but I have never flown anything bigger than a 172!

What the CRJ engineer said makes me wonder what Vfe is for the CRJ and what the first notch of flaps is on a CRJ.

Hard to believe that they used a wing that they shouldn't have but you would think that they could have made a "patch" for it by making the flaps strong enough that you could deploy them by 1 or 2 degrees for climb and in effect make it more of a climb wing without adding too much drag.

Several years back Singapore Airlines was not happy with the Airbus A340s they had because the high wing loading caused by having too little wing area reduced the climb rate so much.

While other airline's 777s were climbing above thunderstorms out of Singapore their A340s were stuck going under and burning more fuel.

I can't remember where I read that because it was several years ago... I think it is probably accurate since Singapore ended up trading A340s into Boeing for 777s.

As I mentioned earlier, in terms of real jet flying, I have absolutely no idea what I'm talking about!

Vfe for CRJ?
First detent of flaps?


thanks!

Was my post really that bad?


Seriously though, I realize that the CRJ's Vfe is probably not any higher than the 757's Vfe of 240 for flaps 1- so my idea would obviously not be useful for a high speed climb.

But If Canadair had recognized the limitation of the Challenger wing being used on the heavier CRJ and made Vfe higher it would have worked.

I was just thinking out loud I guess.

I understand your decision and have no problem with it. It is conservative, safe and as your first officer I would not try to convice you to alter your decision.

Personally, I would continue to destination at a more favorable altitude while keeping an eagle on the fuel gage and alternates available. Taking into account all factors....and assuming the weather was very good...I would plan to land with less than planned reserves...this would include less than legal reserves (this is a legal requirement for preflight only).

If at any time during the continuation of the flight I felt that the fuel on board was not safe...I would then make the decision to divert.

By the way....been there....done that....got the t-shirt.

Can the new software allow a review process for non-professional to be checked by a mod or someone before actual posting?

Yes, that is why I asked about a feature in the new software. I believe that there are good questions from non professionals also.

Are we going to limit posts in the CFI section to only CFI's?

No. But that wouldn't fit the intent of what the CFI forum is for.

Your answer to the exact question you asked was one post above yours. I simply pointed you back to it. That's all.

This particular forum is one we chose to limit thread starters with, in order to keep the queep factor to a very minimum.

You can always post your question in the general or tech forums.......would likely get more exposure there anyway.
