Help Barb get her CRJ 700!

Sean is right. You might be using excessive engine power which is burning your fuel more than it should.

Below 10,000 ft, you should not exceed 250kts (approx. .37 mach). I'm sure there are some charts online that show what speed the CRJ-700 should be at certain altitudes as you climb. I see that the max for this AC is .86 mach. There are converters online such as

Does your AC come with an autothrottle (A/T) switch by chance?

Thanks for the advice -- my other half said that he'll look into the programming for me as soon as I watch Terminator 3 and Salvation with him (not a bad deal!  ;D)... he was playing around with some free aircraft sounds last night and made a lot of our AI traffic with roaring rumbling engines now... pretty cool!

Not sure if this is anywhere close to realistic, my usual routine is as follows:

1) Take off around 160kts, depending on the a/c,
2) Climb at around 3000ft/min and at 220-230kts, usually meaning about 70-80% engine,
3) Once I pass 10000ft, I increase the autothrottle to about 290kts,
4) Back down to about 2300ft/min by FL180, keep it at about 290kts,
5) By about FL250, I reduce the climb to 1500ft/min or so, and leave it at a cruising mach.

Does that sound about right?

Thanks,
-Barb  ;)

Looks good to me

Looks like a good flight profile to me too. Obviously you will encounter differences depending on the aircraft, but that plan seems good as a generic setup.  :)

As a general rule, when I'm trying to test the fuel efficiency of any aircraft, I start up a flight and just let it fly straight, going as far as it can before it runs out of fuel.  Take into account the amount of fuel you need to get it down and on the ground, including at least 45 minutes minimum fuel reserve for IFR flights, and then compare the distance you traveled to the range listed in the specs.  Adjust fuel consumption accordingly.
