My CFI and I are using this dude’s curriculum and I’m 1/2 through my PPL & his program and teaching are really good, stick and rudder good he knows his stuff! Great video Rod thanks 👍
This just gave me a better understanding! Thanks. I honestly took a long time to understand mixture controls and I believe I'll understand even better with experience. Been watching your videos since training for ppl(b4 my written). Now, I just got my ppl and I'm working on instrument. Appreciate it!!
I just picked up a student to finish his private and I’m his third instructor. I’m the first one to instruct him on leaning for taxi in his own airplane.😳
You clear out fouled plug during run up. You taxi leaned out. You enrich on take off. You stay in pattern for closed traffic. On downwind you apply carb heat (enriching mixture). You throttle back to prepare for landing and in some cases alway back to idle. Basically you're introducing conditions that could cause the fouling problems you just cleared. This is not a hypothetical. On my 4th touch and go I applied power to take back off and got severe shaking with no takeoff power. Aborted takeoff at just under rotation. Later confirmed that fouling was the problem. Be careful if you're staying in pattern if you just cleared a fouled plug it may come back. You'll probably be good leaving pattern and leaning mixture. Any input?

It's not the height above sea level (your MSL altitude) that matters here. If your POH says to lean at altitudes above 3,000 feet, then the POH is actually saying to lean when the density altitude is above 3,000 feet. So you'd lean at any density altitude above 3,000 feet. Best, Rod
@@josesbox9555 Excellent. Keep in mind that many POHs references "altitudes" by saying something like, "Lean above 3,000 feet." But those same POHs don't say what that 3,000 feet actually means. Does it mean MSL height? Does it mean Pressure Altitude? The answer is,: It always means Density Altitude. You find density altitude by first finding your pressure altitude and correcting that value for non-standard temperature (using an E6-B manual computer to do this easily). Rod
Always great information. Thanks for posting.

Thank you so much, Veni. That's very kind of you to say. Your comment means a lot to me.

Thank you, Ally. I sure do appreciate your comment very much.
Another great video brother!
Thanks for another great video! Hope to see you at Oshkosh this year!! :)
Thank you, Galen.
Galen, I wish I could be there this year. I have so many projects in the works now that I will have to pass. Next year, though!
Best,
Rod
Brilliant Rod, great idea !!!!!!

Well, I'm happy he found you as his newest instructor.
Best,

GREAT INFO, lot's of pilots are scared to lean must less aggressively at lower RPMs.
Good vid

No
Thank you.
If leaning prevents sparkplug fouling during taxiing, so how does the "rich mixture" contributes to the sparkplug fouling during taxiing?

Rod Machado great help sir 👌 thanks for the positive response. Safe skies always
100 LOW LEAD fuel. You can have a build up of lead on the spark plugs.
What about higher altitude takeoffs. Say you’re in northern AZ or Colorado. Leave it lean or takeoff all the way Rich?
It's not the height above sea level (your MSL altitude) that matters here. If your POH says to lean at altitudes above 3,000 feet, then the POH is actually saying to lean when the density altitude is above 3,000 feet. So you'd lean at any density altitude above 3,000 feet.

@@Flight-Instructor I just found your other Video. Leaning for high density altitude takeoffs.

@@Flight-Instructor Correct. It’s the departure from standard temp at altitude X. I usually go the other direction here in the great state of AK.

I stared at the sun, what do I do?
