    Leaning to peak EGT

    If by "best economy" you mean "most nautical miles per gallon of fuel burned", then running at peak EGT will not be best economy. You get more miles per gallon if you lean past peak EGT, to the lean side of peak. This will also result in cooler cylinders. If you run at peak EGT at 75% power...

    Leaning to peak EGT

    Great questions! “Everything should be made as simple as possible, but no simpler” - well, here (leaning) we have a topic where in my opinion a lot of pilots are happy with recipes which are a bit too simple. If one leans purely based on fuel flow, then you are not accounting for altitude or...

    IFR flight plan - waypoint acquisition

    I've used such "secret" waypoints successfully here and there, but in general it makes things easier if your flight plan fixes are well-known to the typical controller. That includes VORs, of course, but also a number of five-letter fixes which are often assigned to route aircraft around busy or...

    FAA Tells Pilots To Go Analogue As GNSS ‘Spoofing’ Incidents Increase

    That's mathematically correct. But airplanes don't jump around in space randomly. With a known approximate starting position and Kalman filter etc., navigating while in contact with two DME stations works just fine in FMS-equipped airplanes. - Martin

    FAA Tells Pilots To Go Analogue As GNSS ‘Spoofing’ Incidents Increase

    That's actually how business jets and airliners used to navigate before GPS - by using two DME stations (DME/DME NAV). That was not that long ago, and it still exists as a backup in pretty much every FMS today. Works great for enroute and terminal, not so much for approaches or oceanic, of...

    Iowa Aircraft Registration Fee Increase Proposed

    The most painful check I ever wrote for my Bonanza was to the Iowa DOT for the use tax after I bought the airplane. The $35/year since then are more of a nuisance; that amount doesn't hurt me much financially but it's easy to imagine it costs the State of Iowa more to process my transaction than...

    Marker beacon not working

    Yes: do nothing, move on. There is no realistic scenario where the lack of an inner marker beacon receiver has any bearing on the outcome of your flights. Heck, in 25 years of IFR flying I have not once needed any marker beacon, let alone the inner marker. - Martin

    Wright Patt Air Force museum

    I last visited this past summer. You can zip through it in a day, but if you really want to see things in detail, you'd need multiple days - or focus on a portion of the museum. Very much worth a visit! - Martin

    How to set up to land with a dead engine.

    Brian, What type of airplane are you thinking of when you say the difference between a windmilling prop and idle engine is so small? In a high-performance airplane the difference in rate of descent can be several hundred feet per minute at the same airspeed. I agree with your recommendation...

    Cool Photoshopped Photo

    The caption is wrong - it's not an airliner, and it sure as heck didn't instantly freeze to the pavement on rotation. But the photo is real. - Martin

    Battery or Both

    I think this is where the real difference is - not in what's best for starting, but what's best for confirming normal behavior of your alternator once it comes online. - Martin

    Garmin GPS 175 didn't give me a procedure turn when it should have. Help.

    Next time, maybe you can take a picture of the GPS screen anytime you cross a waypoint or something else changes. That will help confirm what's going on.

    "He was such a good pilot..."

    It helps to be 6'3" :cool:

    "He was such a good pilot..."

    Yes, that is so very helpful. Same with the Bonanza. With too many airplanes, there is really no chance to see what's under the cowling unless you have two people and tools available to remove the whole thing. - Martin
