King Air C90GT ?

ummmm that's not going to happen.

The 750's pull more fuel. It's a matter of fact whether it be -35 or Walters. Higher horsepower means more fuel.

Diesel,

That's what I though, more power = more fuel. However I read somewhere that there is the same amount of fuel and range. I just have to find it (wheather its reputable or not, I can't recall).

I have a packet from Beechcraft on the C90GT at home, when I return from visiting the family I'll do some digging.

Same thing on the Inverters.

Aha, OK. Anybody know offhand if that system will be all DC, thereby eliminating the need for inverters, like the 200?

No changes to the 90 except the -135 engines. Blackhawk will still be selling conversions as Raytheon will not be doing any engine conversions on older C90's (talked to a Raytheon rep at NBAA). Also, as far as fuel, the -135 are flat rated to 550shp so you only get better performance at altitude. Can someone else confirm this?

550 comes right from Beech's 90gt Specs

Right you still make 550 at altitude but down low you're sucking fuel.

Whatever the engine is replacing the -20,-21 or if you're buying one off the line is going to use more fuel.

While you have the same amount of fuel in the plane. Flying lower is using more fuel and altitude you're use just a touch more fuel. Of course you're going faster but you've got to go higher to make sure you're somewhat on the same fuel flow. Going higher means more winds that could negate the increase in speed.

We found that while we saved an hour on our trip that we've done for 13 years our fuel was much tighter. We had to fly fuel flows rather than power doing the leg.

But don't worry a long range fuel tank for cheap money and short downtime is on the way. Hopefully in the next month or two it will be STC'd.

no new avionics for awhile and the 135s burn more fuel down low but should get you to altitude faster and since it is a faster and higher aircraft the range should be the same as salem said
only with the pro line do you not need the inverters

 

[Diesel]

you'd think it was that way but it isn't. I know we shortened a trip we've done for 13 years by an hour but we are a lot tighter on fuel when we get there.

So it's not like we are now going farther because we are going faster. We are doing our same trip time and time again but the high fuel burns down low can really kill you. I just end up flying 300lbs a side till we can really climb. NY airspace just likes to keep you down.

Once you get to altitude you're hummin but then again now you're dealing with stronger headwinds.

It just takes a different type of flying than you were used to with the old engines.
