  1. Engine out glide distance

    Happy Thanksgiving everyone! The last thing I want to do is come across as a know-it-all (because I’m not) but I want everybody to consider making a brief flight or two to determine their “actual” glide ratios. Consider that at an altitude of only 5,000' AGL you would be looking for a landing spot within 9 nm (no wind). If you don’t see an airport on your iPad within that distance you’ll be aiming for the best visible terrain (which may or may not turn out to be hospitable). Meanwhile if my engine stops I’ll see a glide-ring with a diameter that’s FIVE MILES larger than yours. Now I have 415 square nm in which to find an airport (or other landing site) while you are limiting yourself to only 254 square nm. That’s 39% less available landing area. All I’m saying is that in my M20J the published glide ratio is excessively conservative. With today’s incredible technology (iPad w/glide ring) and a simple 30 minute test flight I’ve increased my engine-out landing options by 63%! That’s one of the best safety return-on-investment I could imagine. cnoe Sent from my iPad using Tapatalk
  2. Engine out glide distance

    You do have some good points. Pulling the prop back makes a BIG difference IMO. You can see this in most any landing approach by getting stabilized then pulling the prop back to the stop. I also agree that if your prop is "stopped" you'd gain even more, but from all accounts you have to slow to near-stall-speed to get the prop to stop in the J. Unless you were really high I'd be hesitant to waste all that energy just to get the prop to stop windmilling. I WOULD like to know how much difference it actually makes and may do that someday; if I do I'll report my findings back here. The "throttle position" brings up some interesting questions as well. Once the prop starts "pushing" the engine, manifold pressure increases dramatically. My biggest concern would be the consequences of my engine coming to life at WOT while preparing for an engine-out landing. It should be a non-issue if handled quickly but it could also prove startling in a critical phase of flight. For everyone's viewing pleasure I'm attaching 2 pics of my JPI data (manifold pressure, RPM, and EGTs) for a "simulated" engine-out (idle speed only = ~860 rpm) vs. a "true" engine-out (ICO position = ~663 rpm). The RPM difference between those 2 scenarios is approximately 200 RPM in my plane. Note: The JPI quickly shuts down once the engine quits making significant power which truncates the graphs somewhat. As stated before, in my plane 14:1 or 2.3 nm/1,000' is a conservative glide expectation either power-off or idling. For me these are good numbers. Your mileage may vary. cnoe

    I didn't find that to be the case. I'm anything BUT a pilot with "perfect technique". Anything within a 5 knot range around 88 kts should buy me 14:1 in my J.

    This topic was discussed in great detail back in March 2016 when I conducted glide tests in my M20J. My findings were that the published glide ratios/distances were overly conservative. For me personally, I set the (wind corrected) glide distance rings on my moving map (Foreflight) to a ratio of 14.4:1 or 2.37 nm/1,000' agl. In the event of a power-off event I want to know ALL of my options, not just the ones that Mooney's lawyers conjured up for me. Of course I'd look for the closest acceptable landing spot, but I wouldn't put it into a hole in the trees if my calculated glide range would allow me to fly beyond them. I believe that a CONSERVATIVE figure (for MY plane) is 14:1 or 2.3 nm/1,000' agl. Your numbers may vary; you'll never know unless you practice this. My personal testing was done with both "power on" and "power off" (i.e. mixture pulled to ICO) with the prop control pulled fully out. The difference between "idle" and "off" was less than you'd expect. Somebody may flame me for flying around with my engine off but it's really no big deal. I also have no issue running a tank to empty if the flight scenario requires it (though it rarely does). All the details are found under a previous post titled "M20J or glider".

  5. Trim switch issues

    I’ve been offline a while and just saw this. My setup is very similar to yours and I’ve been through this and resolved it. PM me if you’d like more info and pics. It involves tedious detailed repairs but isn’t expensive. Sent from my iPad using Tapatalk
  6. Heim F34-14M - $25 including 1st-class mail shipping (US only). They currently sell for $34.50 each + shipping on Aircraft Spruce. I bought 4 new rod-ends/Heim-bearings a couple of months ago prior to annual to tighten up my gear doors on the nose and have one left over. The parts catalog specifies a Heim F34-14N which has been superseded, but the F34-14M unit can be substituted for 3 of the 4 required rod-ends. The remaining one must be machined thinner on the head in order to allow a greater angular rotation and this "special" part isn't available from general suppliers like Aircraft Spruce, etc. It's also twice the cost. So if anybody wants to save a few bucks on this unused part just let me know. Payment via PayPal or check.

  11. By "seal" I mean put a bag or plastic around it and seal any openings with tie-wraps, tape, safety wire, or whatever it takes to prevent ANY Corrosion-X from penetrating. Keep in mind that it's designed to penetrate everything and will even get between lap joints. I plan to actually remove my roll servo next time I fog the wings. Sent from my iPad using Tapatalk

  13. Guys, if the new G5 and Autopilot options interest you then please contact Garmin as noted several places above. Here's the reply I got following my e-mailing them earlier this morning.
  14. Email them right now at and tell them you fly a Mooney M20 and want it added to the AML.
