After last week's great flight down to Atlanta and back to NJ, I've begun to
seriously investigate upgrading "my" aircraft to an SR-20. By "my" I mean that I currently rent, and for long distance flights meant more for vacation like the one to Atlanta, I rent a 172SP. I'm very happy with the planes I get to rent, as each (of the two available) is equipped with GPS, moving map, and autopilot, and one even has an HSI that automatically syncs up with the magnetic compass... a very handy gauge on really long flights. I spoke with someone at the Airshares office at Caldwell, NJ, and got a good overview of the price structure for the SR-20. They don't actually have one available there yet, as there isn't enough interest at the moment. But I don't qualify for the SR-22 yet... I have about 195 total hours, and their insurance requires 350 + active pursuit of an instrument rating (which, incidentally, I earned a few months ago). So I'm really only lacking the flight hours, and the SR-20 sounds like a great way to move up without stepping up too much in too short a time. I'm curious what experiences any SR-20 flyers out there have had on both short hops, sightseeing trips, and on longer distance trips as well. I want some extra speed, and I like the fact that it can carry a bit more of a payload than a 172SP, but since I haven't flown one, much less to a faraway destination, I don't know if it will really be worth the hassle of the upgrade. I'm interested in hearing how well it performs, how comfortable it is, how useful it is as compared to 172s, Warriors, etc. Thanks! -- Guy Elden Jr. |

I get 130 knots at 9 gph. It carries 540 lbs with full fuel and will fly for 5 hours with reserves. |

At lower altitudes I am limited to 23" mp or less (65% so I can run LOP), at higher altitudes the mp is limited by the altitude and the fact I can't run full throttle without running at max rpm (the throttle is connected to the prop governor and can't be overridden so if you run at full throttle you run at max rpm). |

So I'm really only lacking the flight hours, and the SR-20 sounds like a great way to move up without stepping up too much in too short a time. I thought about Airshares for a while. I still have it in the back of my brain. But, at least for now, I decided to go the "club route" instead. I'm in a club which includes a 182 and a 182RG, as well as a couple of 172s. The down side, as compared to the Cirrus, is that none of these are a Cirrus. That is one hell of a nice airplane. I even deliberately avoided the open house Airshare had at CDW a little while ago, knowing what would occur if I went. But, just to be mean to myself, what are they planning to charge for their -20s? - Andrew |

the SR20 only has a 200 HP engine.
now if it was able to pull the landing gear up, I am willing to bet his speed would increase by quiet a bit.

It carries 540 lbs with full fuel and will fly for 5 hours with reserves. According to the Cirrus website, the SR-20 cruises at 156 kts at 75% power. We all know that "book" speeds are sometimes a tad optimistic, but 26 kts???. I get better than 130 kts on 9 gph in my Arrow, with a lot more useful load. If I bought an SR-20 and it only gave me 130 kts at best cruise performance, I'd demand my money back! -- -Elliott Drucker |

... According to the Cirrus website, the SR-20 cruises at 156 kts at 75% power. What's the fuel flow at 75% power? For a 200 hp engine, my guess is that it's significantly more than 9 gph. Or conversely, it seems likely that the 9 gph isn't 75% cruise. If I bought an SR-20 and it only gave me 130 kts at best cruise performance, I'd demand my money back! Art didn't say 130 knots was his "best cruise performance". He said that's what he gets at 9 gph. I assume he used that figure because that's close to the fuel flow in a Cessna at normal cruise settings (with a 160 hp engine), and so gives a rough apples-to-apples comparison between the airplanes.

I assume he used that figure because that's close to the fuel flow in a Cessna at normal cruise settings (with a 160 hp engine), and so gives a rough apples-to-apples comparison between the airplanes. In my Arrow, which like the SR-20 has a normally aspirated 200 hp engine, I can true 135 kts at 65% with a fuel flow of around 9.4 gph. 9 gph would probably be about 60%, give or take a little. Since for a given airframe airspeed varies as the cube root of applied power, assuming equal propeller efficiency (and that's a good assumption with a constant speed prop) 130 kts 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. -- -Elliott Drucker |

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.
