AMF BE1900s

[TheDogsBollocks]

Anyone in the know? I heard a rumor that AMF was trying to put smaller than standard engines on the BE 1900.

No, we have to use a reduced power setting (1900 ft/lb torque) to save fuel. Considering the old power setting was a conservative value (2400 ft/lb torque), we now basically fly a BE 1900 at the same speed as a BE99!

What do you cruise at in the 1900 with 2400 and 1900lbs of torque? We used 1400lbs in the Bandits and that gave us 200-210kts.

Next rumor?

Oh, well, since you asked...

-We are getting an exemption to fly the Brasilias single pilot.

-There is going to be a pay raise this decade.

-All of the airplanes are getting Garmin 430's.

-OH... how could I forget the ATR's that we're getting!


Where do people come up with this crap?!?

There must be a few characters who sit at their layover and brainstorm asinine rumors to spread.

2400=@200/210kts

1900=@180/190kts!

Wow at that lower setting your not going any faster than I am in the 310/402! Probably makes a big differance in fuel burn though.

Actually, those numbers I gave are meant to be KIAS not KTAS, sorry for my error.

Put in the updates for a Jepp national kit and get back to me about some of us getting them for free. Hell, I don't even do it that often and I hate the thought of it. I really feel for the E120 crews on that. And the Jepp checklist isn't much fun either.

As per the power settings, I think someone reached elbow deep and just pulled some BS numbers out. We don't use them anymore for our Metros as we did (specifically KSU did) some research and found that our old power setting were just about as efficient as could be run in the plane. In fact, at altitude those power setting weren't as efficient as using more power because you'd be flying around 7 degrees nose up wallowing along at 160 kts. That research was forwarded along with a pretty snappy formula for determing best power for speed/altitude in SA227's. Don't know what happened to it from there.

Brasilia flying is not in my near future so the joys of a national chart revison are not mine to endure. In regards to the power setting issue, I find it hard to believe that significant fuel saving can be made, especially when you consider that our flight segments are pretty short overall.

What astounds me is that we have to comply with these settings flying our DHL runs-DHL pays for the bloody fuel! On the short flights I have made in the Metro with the new power settings, no significant fuel saving have been noted!

 

[DirtyBeech]

Feel for you on the DHL stuff. Like I said, we ditched them because they were and are BS. I'd rather do what's best for the company than comply with an unresearched and wasteful policy in terms of fuel and time.

Btw, if you're interested here's the formula. Start out at whatever power setting gets 200 kts. at 10,000 feet. We both know it should be about 50 TQ. For every 1,000 feet above that set the power to reduce that speed by 2 knots. For example:

11,000-198 kts.
12,000- 196 kts.
13,000- 194 kts.

and so forth. I know you can't officially do that for DHL, but it might be something to take a look at.

Interesting, you can be assured that if such data was researched and compiled by the BUR "politburu" it would have become policy pronto!
