Hello Martin: Saw a link to your crosswind technique video today on Beechtalk and decided to check it out. Was rewarded with these two great videos you and Doug Rosendaal put together a few years back. They were a great refresher for flying my P35 Bonanza. And they took me back to my taildragger flying days too. Thank you! And what a great CFI Doug Rosendaal is. Very professional yet down to earth. By the way...I flew to Cedar Rapids a couple of years ago to fly with you as part of BPPP. I much appreciated your expertise and the pointers provided. Take care: Nick Wynen

Martin's landings are excellent!! 👌

Really interesting 💪👌. Thanks for your great video’s. You inspired me to start a aviation channel 🤗 with my pa28 🤗

Nice video, thanks Martin. Particularly liked seeing your comparative engine performance figures at about minute 24:00 onwards. Does George mention why the CHTs (though commendably cool as they are) run a little hotter in your trial, by about 5-8 degrees on the G100UL fuel vs. the 100LL, at the same fuel flow? Perhaps it's that extra 3% energy using the G100UL?

Annunciation of mode on the PFD is a Human Factors issue and important. Keeps the pilot informed as to the autopilot mode of operation. The Bendix FCS-810, a later generation then their M4 autopilot, has or had a variable angle intercept function. When invoked, the annunciation was heading mode plus Approach Arm. When the intercept with heading steering became < 45 deg to final approach track, the annunciation became Approach Mode and Heading mode automatically canceled. Intercept was performed rolling onto final track. AP went to track mode from intercept. Don't understand why Garmin AP doesn't have the same capabilities. Maybe it does, just unfamiliar and just don't know. Seems like a regression in functions. Pilot should be aware of what the AP is doing at any time. Same goes for Flight Director. As an aside, all APs in aircraft and especially Boeing should have pitch trim in-motion audio such that the flight crew knows immediately when the AP is auto trimming the pitch axis of the aircraft. That may have prevented the two foreign B737 from crashing straight in. But I digress. Have extensive AP repair and flight test background at MSP twin cities.

Don't like the PFD. Lacks AP mode annun. Also AP could be more friendly, needs approach arm and approach capture + annunciation. Have had older APs with these incorporated. What a SET BACK! Not happy with this AT ALL. Was an AP repair specialist at MSP international airport. Many AP test flights via coupled approaches. Mostly twins and turboprops.

Another great video of usefulness to general aviation pilots.

Meigs field was the island airport i enjoyed in flight sim and youtubes, great channel

Jimmy Franklin had the first jet Waco. I helped with the jet engine install.

Great job

I can’t wait for lead to go away here. I have a non related question for you Martin. I have been flying my RV6 at reduced RPM and operating over square. O-360 with CS prop. Mike Busch explains the benefits in a video and I am giving it a try. Lower tip speeds reduce drag and noise. Lower heat generated by friction. Lower losses due to less piston inertia. More time for fuel in the combustion chamber to completely burn extracts more energy per volume of fuel. Lower cylinder head temps. Lycoming engine manual has oversquare limits of 1800 rpm and 22”. I aggressively lean and fuel flow is about 5.2 gal at 7500’ wondering if you have tried this in the Bonanza?

At the glider club where I have been learning to fly we use 45 degree banks on final turns in the pattern. My one instructor elligntly explained the one day exactly what you say here that if you do not try to maintain altitude your airplane will never stall. I prefer a bit less of ban being a low time pilot and sometimes not being perfectly cordinated but It makes sense and as long as you keep the airspeed constant you are fine.

With individual cylinder monitoring lean of peak saves fuel and the engine runs well. No damage.

No lead fouling all Good, lead was and is an octane booster to some extent. Lead gone is a great thing.

So when we will get this fuel.

Fantastic job Martin!! And a HUGE thank you to George and Tim for providing such intimate up close access to this tremendous new high octane fuel. Absolute GAME CHANGER.

As always - excellent video...

I'm still waiting for more economical diesel engines so that we can all just use JetA available everywhere.

CHT’s at 300 degs will result in cylinders plugged up with lead on 100LL. You need to run them at least 300 degs for the lead scavenging additive to work.

Switching the fleet to G100UL is not about technical issues, it’s political. Follow the money, and at this stage, AOPA is part of the problem. If the Feds banned leaded fuel, G100UL would be rolled out within a week. It’s the same fight that took place when getting the lead out of auto gas. People willing to sell their souls for a buck.

Great video, so nice to have greater detail on this subject!

Can't wait for unleaded avgas to be widely available in the US. My Rotax would love it! Fewer oil changes and longer life on the spark plugs! On another topic, it looks like you're wearing the Axis headset. Great headset!

In Brazil we can t fly lean of peak. Air temperature is too high, it s hard to get lean, instead I try to fly rich of peak because it easier to avoid red box here. Thanks for the video.

When I was a kid... I worked at a chevron station just when leaded fuels were being phased out. I also had a 68 camaro. (This was mid 80's) I remember needing to change over to unleaded, and I was assured nothing bad would happen. When I finally put in a tank of "Regular UL", I had detonation. I had to run premium, and I had to make the carburetor slightly richer to keep my power. (I could have run regular if I wanted to drop ignition timing) I'm guessing this is where some of the old issues came from. A typical "Mom" would be forced to switch in her station wagon, and nothing would be adjusted. The light, constant detonation would eventually take it's toll on the engine. I wouldn't have an issue with 100 UL since we still have that "100" octane base fuel. I look forward to it being more wide spread. BUT... they need to figure out a way to make it a price that doesn't discourage GA. $6/gal has already slowed GA.

I am so excited about no-lead avgas, finally. All the work that GeorgeB and the team have done…. Has finally put all of us in GA in such a good spot, to finally get rid of lead. It will take content and advocacy just like this, to get the real word out to a community that is sometimes hard to change. Well done Martin!

Thank you, Martin. Very informative. George also debunked a couple of things I had heard and wondered about G100UL. I do have a couple of questions, though. How much more per gallon is G100UL? In looking at a Wikipedia article, it says that G100UL contains absolutely no lead products whatsoever. So, what's the 'UL' mean? Anyway, great video. I'm not an active pilot, but I still enjoy aviation and the aviation business, and I was wondering and concerned about the availability of an 'Avgas' product. With Diamond offering more and more Jet-A fueled piston twins, I still expect that to be the future paradigm, and aviation moves to one fuel source. But, in the meantime, we still need some sort of avgas for the fleet that we have, and will continue to need it for the foreseeable future.

Martin, big fan of your videos! I am not happy with my Bose/Aerox headset/oxygen cannula combination- wires going everywhere around my head. What headset and oxygen combination do you use? Your setup looks very clean and unobtrusive.

I would ASSUME that thee lack of lead additive would bring the price down somewhat. True? Does a gallon of G100UL weigh less than a gallon of 100LL?

If you are used to and happy with a six pack, I find that the large screens are too busy with needless information and pictorial stuff. That's why I feel more comfortable with the Aspen AH and HSI. In real IFR conditions it better to keep it as simple as possible.

I can't wait for Unleaded! I'm not sure if Transport Canada is keeping their eyes on GAMI. I sure hope so! 😅

Proactive? 50+ years after we removed lead from automotive fuels, hardly sounds proactive. Anti airport groups are now using elevated lead levels around my home airport of RHV, to threaten closer. We needed to remove lead in fuel decades ago, and I hardly think your characterization of being proactive is appropriate in this case.

Martin, another fantastic video. I learn so much from your excellent IFR flying. Please keep them coming!

So if I use auto fuel I have to use 100ll from time to time to keep lead in the valves to prevent damage. But I can run 100ul with no problems. Oh I’ll have to run nothing but 100ul because without 100ll I can’t follow auto gas STC.

Great video and information. And glad there is a fuel that is ready to replace 100LL when time comes and we all know it’s coming like it or not.

I bought the STC last fall as soon as I could. I don’t think it will be available anytime soon but I feel this approval effort which must have been a significant investment needs to be supported!

Great Video, our QB meeting had a speaker a last month to talk about G100 fuel and it sounds like right now is getting it to FBO's, sounds like it can only be transported by truck from the refinery. Lot of great info in the video, thanks have a great day, Charlie

George Braly has had quite a career. From battling tobacco companies as a trial lawyer to now doing all this complex fuel engineering is extremely impressive!

Great video. Thanks for the information

This poor guy is getting stonwalled so hard.... Those that be want him to fail so bad, i hope George persists and is successful

I’m going through my multi engine training now and my instructor said to watch this video as my homework. I’m glad I did as it is so informative, thanks for making it! 😊

Martin, why do you run so lean at altitude? 30 LOP seems quite a bit leaner than necessary for the conditions .

Lead has nothing to do with detonation!!!!! Octane does!!!!!

Thanks for the real world demo of G100UL. It looks as if it will perform the same with minimal differences. Now when are they going to start distributing it? Would be nice to be able to fuel up at my home airport (Reid Hillview KRHV) again.

Thx for dispelling the preconceived thoughts about this new fuel.

I have the G100UL STC on my Mooney M20M Bravo, it's got the TIO 540 AF1B, thanks for the great video. I wish they could roll this fuel out sooner than later, but that's where we're at right now. It's my understanding there's approximately a million gallons of G100UL stored in Louisiana ready to be sold, but it's up to the current distribution channels to get it to market 🤞🏼

It was interesting. We got rid of lead in cars by the late 80s. I am really surprised aviation hasnt changed over yet, or the federal government hasnt mandated it yet.

Price?

One side benefit of unleaded fuels is there will be no lead fouling of engine oil, piston rings, and spark plugs. Removing the lead from fuel will enable the use of full synthetic motor oils which should result in greater durability and cleaner engine internals. A win for the environment and a win for engine durability.

Some of Martin's best videos are when he sits down with brilliant-minded general aviation experts including Doug Rozendaal and George Braly.

I am sure that UL is coming but with as much as we are currently paying for 100LL its hard to swallow another premium $$ on top of what we are paying now.
