My GPS has a "nearest button" which only takes a punch and it=20 shows the airfields closest to you. The second factor (before turning)=20 is to assess the wind direction. In one engine-out case, I had a choice=20 of two airports both 12 nm away, but one was downwind. When you are=20 gliding at 70-80 mph you greatly extend your distance by heading=20 downwind - IF ,of course, that takes you toward an airport.

Wow !! Ed what a story to tell.

Good to here that your back up system work j= ust as it should, this is why all the redundancy is planned and build into= the systems.

Still practicing regularly a =E2=80= =9Cengine out=E2=80=9Dand try and see if i can reach the airfield, but it i= s different if you know that you can just push the throttle to reach the la= nding strip

I only have 93 hours off PPL experie= nce on my log book. Hire and Fly at my local flying club. Most of the time= on the Piper 180 ( PA - 28)
Building and building on my homebuild = project but will get there or so we all believe=C2=A0
