    What causes engine roughness when you lean too much?

    The real culprit is uneven air fuel ratios between the cylinders. As you lean to the Lean of Peak EGT side of the graph, the power starts to drop off. If the air fuel ratio is the same in every cylinder, then every cylinder produces the same amount of power and the engine runs smoothly as you...

    Drop-in 100LL Replacement "Impossible"?

    I believe they do. I took their advanced pilot course and have read articles and seen interviews about the test stand, it's capabilities, and what they learned about engine operating characteristics. The information they learned contributed directly to the building of GAMI injectors and other...

    You are right. I wrote 108 MPH but I was thinking knots. My mistake. Thanks for catching that

    Where are we on EGTs and CHTs?

    >>>"saying that an NA engine running that hot would be doing so because it was substantially too lean. ">>> IMHO if that statement were to end with the words "while running Rich of Peak " it would be accurate. But without those words it is inaccurate. As long as the engine will run smoothly...

    GPS backup

    While there are 592 radio stations in Florida, most of them are FM which legacy ADF cannot use. According to Radio-Locator.com Florida has 209 AM stations, more than enough to dial up a station within 40 miles of your location in a pinch. I live in Virginia which has 131, and the GPS...

    GPS backup

    NDBs are MUCH cheaper to install, operate, and maintain, on the order of 10:1. If you are looking for an inexpensive backup to GPS they give a lot bang for their cost.

    GPS backup

    Not too long ago I flew through an area where GPS coverage was interrupted or possibly jammed for about ½ hour. I continued navigating by dead reckoning and dialed up the nearest VOR to use as a reference. Fortunately there was an active VOR along my route, but VORs are being decommissioned...

    Custom Checklist

    Today I flew my new checklist. I am very happy with it. Thank you all for your replies. We have a good bunch of fliers here!

    Custom Checklist

    Your experience and input is exactly what I was looking for. I want to convey that customizing a checklist for the airplane you fly is a good idea. It makes you think about your procedures and efficiency as a pilot and it allows you to tailor your list to address quirks particular to an...

    Custom Checklist

    Do you have a custom checklist that you can share with us? And maybe you could tell us a little about what makes that airplane unique and how your checklist addresses that? Thanks in advance!

    Custom Checklist

    We are all familiar with checklists but to the newer pilots are you familiar with the concept of flow? I once had an instructor Is who introduced me to the concept of flow across the airplane controls. He pointed out that the checklist was fine if you had time to do it, but if you need to get...

    School Me On Short Wing Pipers

    You are correct that Clippers and Pacers are very capable aircraft. Pacers have more HP and can climb a bit steeper than Clippers. Clippers have control sticks and Pacers have yokes and flaps. Clippers don't have flaps, so that might give the Pacer the edge. I used to own a '68 Hershey Bar...

    More oil == cooler engine temps?

    I am going to look at this a little differently than most of you. The original question is posed in reverse. More oil = cooler oil temperature is backwards. LESS oil (if too low) WILL lead to higher oil temperatures, due to oil foaming or cavitation. But if there is enough oil to keep the oil...

    Who or what flights qualify for FF?

    You may want to ask for transition through class Bravo airspace. If you do, ask for a specific point-to-point line at a specific altitude. An acceptable request might be as follows: Detroit approach November 1935 Yankee Request class Bravo transition from Delta uniform hotel direct to 2 Echo 8...

    Who or what flights qualify for FF?

    Here is another point you might want to consider. While planning your flight it is better to remain outside of class Bravo and Charlie airspaces where possible. That means flying beside or above to remain clear. Yes you can fly underneath the shelf but if you inadvertently bust through the...
