I must be either lucky, or I'm running too low a power setting. With
450 hours under my belt on my 914 tri, the average is 4.3 US GPH
(mogas). I usually cruise at 4900 RPM and 31" MP..............rarely
less, and sometimes 5000 RPM and 34" MP when I'm in a hurry to get
someplace. I have a Whirlwind CS prop.

These flow flows are pretty similar to what I see on my 914 Mono. I
have a dual sensor fuel flow on my EIS and over the last 400 hours I
have found it pretty well "nuts on" for accuracy. - Paul

Hi Simon,
I wish they were. I recently put over 1000 miles on N214KS and the
fuel required to fill the tank agreed to within .1/.2 gallons of what
the gauge said I used. Plugs look normal.

I think you figures might be a little suspect. The Rotax 914
Operators manual give Take off performance as 5800rpm, 39.9 inHG and 8.7
us gph. Max continuous as 5500rpm, 35.4 inHG and 7.2 us gph. (ref pages
8-2 & 10-1)
Are you sure that your fuel flowe sensor is correctly calibrated?
Are these airspeeds IAS or TAS?

Duncan,
I'm afraid this data will get rearranged but here it goes. This
test was done at 5500' at a max weight of 1450lbs. with very little
deviation from standard day temp. Airspeeds are within 1 kt. These
airspeeds appear to stay constant up to 12,500 (the highest I've
observed)
1. 100kts, FF 3.8, RPM 4500, MF 25.
2. 116kts, FF 5.0, RPM 4800, MF 28
3. 129kts, FF 6.2, RPM 5000, MF 30
4. 134kts, FF 7.6, RPM 5250, MF 33
5. 140kts, FF 8.3, RPM 5500, MF 35
6 148kts, FF 10, RPM 5800, MF 40
I'd appreciate if others would post there data.
