Just returned from the time to climb check.  Field 1050' ASL, baro 30.40"Hg, OAT 9 C.  80 gallons of fuel,  2 on board @ 420LBS.

From a standing start, climbed at 120KTS, (Vx= 80 KTS, Vy= 104KTS)  Could have climbed steeper but the sun was low and made it hard to see. I will have to do it again to improve the numbers

2000'  0:50

3000' 1:29

4000' 2:06

5000' 2:52

6000' 3:38  less than 5 NM from airport

7000' 4:22

8000' 5:10

9000' 5:54

10,000' 6:43

11,000 7:42.  12 NM from the airport

Interesting data. Have never done a time to climb test in my C. What I have done is climb at WOT and 2500 rpm and trimmed for 120 mph (my typical cruise climb with temps staying below 400) until she could climb no more. I was 400 under gross and she stopped climbing at 16000 (still showing 120 mph indicated). Temperature at departure airport (KCRG) was around 70 degrees F. Pretty sure if I had increased to full RPM and continued climbing at Vy (around 85 indicated at 16000 feet) she would have gone another couple of thousand. Pretty cool considering at 16000 feet and 2500 rpm an O-360 is making just a little over 60 BHP.

So it took you 7:42 to climb from 10000 to 11000 or it took you 59 secs? If you are climbing at 1000'/min at 10000', what kind of turbo do you have installed?

59 seconds and Clarence gets his power the old fashion way through 400hp (PA-24-400) because Pug Piper thought turbo's would never take off.

My HP (200) divided by M20Doc's HP (400) times my 10K climb time (10:20) = 5:10 (adjusted for HP deficiency). I'm feeling better now.

Very cool!  Ok - since we aren't talking Mooneys anymore (Clarence was still a piston at least)

I once was reading on barnstormers an experimental category modified aerobatic airplane for sale with a turboprop engine where the owner was claiming that it would climb from 0 to 18000ft in 2.5 min.

F16 Rate of Climb (wiki) 50,000fpm.

The jet powered Waco show plane (many of us) saw at Oshkosh and other air shows - I had the chance to ask him - he said he climbs at 8000fpm and is limited only by the redline on the airframe because it can climb straight up.

Space Shuttle: 31 sec to 10,000ft and 99sec to 100,000ft. (I thought a Mooney rocket was fast - but a real rocket is faster...)

Just returned from resetting the time to climb in the P brand airplane. 10,100 foot climb in 5:54.59. Vy plus 10 mph.

Good lord! Six hours to climb to the 10,000' step! Hope the glide back down was good. My C only carries fuel for 5:30:00 flying, but I've not tried timing it to the second. :D
