quickest alt gain on Cessna 150?

And go fly one, they’re a ton of fun. I’ve been up to 10,500’ in one.

Me too, but boy it took a LONG time to get there.

I did 12,600 in my 150F, starting from 340' in winter and it took 30 minutes plus or minus. Was still climbing at 300 FPM

I like the "fly naked" idea.

you obviously haven't seen me in person.

Follow the POH. The 150 doesn't take any longer to gain altitude than most other old certified airplanes. Standard day, full fuel, and my 175 lb self I see 7-800 fpm from SL to 4500 or so then it starts to fall back towards 500-600 fpm up to 6500 which is the highest I have taken it so far. At gross you will give up 1-200 fpm. This is in a 1963 Cessna 150C

Yup, but your 1963 150 is a straight-tailed bird. No back window. When Cessna added that sharp drop behind the cabin to add the window, they added weight and a bunch of drag that hurt the performance badly. Slower climb and cruise both. Vortices off the inboard ends of the flaps. Such an improvement.

Just went up again today and at the 150 topped out at a density altitude of 13,600’. Checked it using a density altitude calculator and both true and density altitude were within 100’. Nice flat temperature profile as the temp on the ground was 18F and the temp at 13,000 was 18F. Was still climbing around 150fpm, but certainly slowed right down, potentially because I got carb ice right at the top of the climb. Full power at 13,000 must not make enough heat to be considered “full power”. Got to remember that. Luckily I was at 13,600 feet and could have glided engine out for an entire county.

When I owned a '76 150M, I used to climb to 10K just to mess with the controllers of the local Class C. Got pretty good at thermalling the 150 during the summer months.

Strap a Turbine to the front. She’ll
Climb faster

Now I really want to see some insane person build this. Do it with the Aerobat also. LOL.

Declare the fuel emergency prior to takeoff. LOL.

The cruise chart for the 150M:



For each altitude, the top setting is full throttle. At 12,000 you'll only get 2650 RPM and 57% power in a standard atmospheric condition.
