I have owned a Cherokee 6/ 260 since October and with each flight I am becoming more and more amazed with it's capabilities.
Sure, it's not super fast, but for what I need it to do, it is amazing. I only fly "happy IFR" which is simply poking through a layer or two on my trips and have zero need to push the weather.
My "milk run" flight is 335nm one way. It's a 680nm round trip which includes a stop on the return trip to clear into customs. My average taxi and flight time on the tach is 5.6 hours. The worst time I have turned this flight in was 5.9 and the best has been 5.2. That is running at 65% power.
Doing the math, I come out at a average speed of 121 kts. and a fuel burn of 12.7 GPH. That is with ground taxi time and 3 climbs at 25 squared to altitude.
The whole time I am able to cram 993 lbs in the aircraft with full fuel tanks and take that more than 6.6 hours! On my most recent trip, I logged 5.7 hours on the tach and put 72.7 gallons in the tanks. That means I had better than an hour left of fuel using my JPI calculations.
On an interesting note related to the JPI, I have found that it is amazingly accurate as long as you back it up with a stopwatch. I purposely ran one of my tip tanks to calculated exhaustion and watched the JPI flow "increase" just before my calculation showed empty. Switching tanks was no issue.
I'd be hesitant to find another single engine that can do the same.
