Density Altitude Flying

Try DA in Arizona!!

Nice memories. Years ago I got my seaplane rating in Columbia, California and we flew out for some high altitude work to Lake Tahoe. Also got a little swim in on a hot day. Even with a 150HP Super Cub on straight floats with a Borer prop takeoff and climb performance was marginal.

Yet instructors expect students to train in the Denver area with density altitudes at 9000+. Nothing like buzzing the house tops for 15 miles to get to TPA.

it teaches pilots valuable skills training in that environment.

Friend used to let me fly his C-152's, standard startup and run for takeoff at the airport he was based at,, 300 ft AGL, always insisted back mixture out an 1/8 of an inch during the summer.

I was hoping for something instructive, but this video is only a nice chat. I learned nothing that I didn't already know. Too bad, it's an important subject.

So incredibly superficial! No mention of POH no mention of mixture full rich never equals best power not even at sea level. Mixture full rich in general equals to max engine cooling.

[@SoloRenegade]

and many engines, such as Lycoming's, say to not be full rich for more than 3 minutes. even they want pilots to back off the mixture at least slightly at lower altitudes. But adjusting and optimizing the mixture is just not taught well enough. I get a solid 4.75-5.0hrs out of my C150 with VFR reserve, burning 4.2gph, which is very close to the POH numbers, even at low elevations (pretty good for an old airplane that's slightly overweight and higher drag than from the factory). People try telling me a C150 can't fly for more than 2hrs at less than 7gph (because they fly around at full rich). I even asked the Chief Engineer at Continental once about how I was flying the C150 and he confirmed I was doing everything correct and to keep doing it the way I am doing it. But I also trained at High DA where leaning is mandatory, even for startup, taxi, and takeoff.
