Airshares SR-20

at 60% would correspond to 140 kts at 75%, which, not surprisingly, is
almost exactly what I get in the Arrow. (141 kts to be precise.) That is
still a far cry from the 156 kt "book" 75% cruise speed for the SR-20.

That's a number that a) is a lot closer to the published value than the one
you were originally complaining about, and b) is extrapolated by you, not an
actual reported value. You'll notice another SR20 owner reported nearly 150
knots on 10.6 gph. A variety of other differences could easily account for
the rest of the airspeed variability.

My fuel flow, at 65% power, for my 200 HP T-Arrow is about 12 gph , but at
65%
power I cruise at 150 KTAS (or better - I plan for 150 tho) and can fly
non-stop
for 700 NM - But this is also flying at 8000-13000 ft.

First of all, 12 gph for 130 hp sounds to me like a lot of gas. I can get
the fuel flow on my 270 hp engine down to 12 gph at around the same power
setting (60-65%). You might want to double-check your engine gauges.

Secondly, turbocharging isn't a fair comparison (you as much said this),
since you get to enjoy full power operations at the higher altitudes where
true airspeed increases.

I have a shadin fuel flow monitor, it is pretty consistant with the airplanes
fuel flow gauge. I can lean it out more but that is best power setting. since I
only fly at 65% power, I dont want to lose what I have by skimping on the fuel
mixture. Plus this is a power setting, its not 65% due to altitude or fuel flow,
I set power (2400 RPM / 30" MP) for 65% then lean for best power.

the engine in the t-arrow is a cont. 6 cylinder, fuel injected, the normally
aspirated one is a 4 cylinder lycoming. why piper stopped making the T-arrow I
dont know, I think its alot better the the normally aspirated one (I have fown
both). But if it came down to buying a new airplane, An arrow or a SR20, the
arrow new is 271k (standard listing) - I think the sr20 would win out. Piper is
going to have to do something or cirrus is going to put alot of hurt on them and
other companies.

Dan,

That seems awfully slow. Is that TAS? What altitude?


See the latest issue of Aviation Consumer for a comparison of the DA40
and the SR20. Average speed seems to be 145 to 150 knots TAS, at around
10 gph.

ArtP is quite well known here for not liking (his) SR20.

Jeff,

I am willing to bet his
speed would increase by quiet a bit.


5 knots max, Cirrus says.

That is [130K] TAS and at any altitude.

Dang! My 172RG will do 136 KTAS at 6,000' on a standard day, full
throttle, 2,500 RPM.

When it works, it is a roomy, automated, and slightly faster, and much
more expensive 172. I get 130 knots at 9 gph. It carries 540 lbs with
full fuel and will fly for 5 hours with reserves.

According to the specs this aircraft will do 156 KTAS 8000' 75%

Are we being BS'd. I usually find Cessna and Piper aircraft to make
there published numbers.

On COPA (www.cirruspilots.com), even the staunch supporters
acknowledge that the plane won't do the POH numbers.
