Re: Engine failure best glide speed descent rate

The video does present a valid condition. Some airports don't have attractive off-airport options nearby. Most of us could come up with examples (I'm lookin' at you, LDJ). So we have to recognize when we're rolling the dice.

Fuel Tank Finger Filters

I had an incident yesterday that may result in removing/checking one of these (right tank, specifically). Does anyone know offhand whether these can be removed without pulling the wing?

Re: Corrosion within the laminate

Hi Rich, Thank you, so I will remove the T profile and inspect with an endoscope. But from what I understood, the suspected corrosion of this problem is inside the laminate on the metallic part ? Impossible to see it, isn’t it? Arnaud. The idea is to see if it's more than on the exposed outer surfa...

Re: Corrosion within the laminate

Arnaud, There is a small gap between the wing and its root and you might be able to examine the inside portion for corrosion. with an endoscope. If there isn't a problem inside the wing, I would try using polishing compound, by hand (finger, actually) on a rag and remove the surface rust. Use a plas...

Re: Engine failure best glide speed descent rate

Ran some what if stuff for a 180-deg turn. The numbers I plugged in assume a willingness to make a coordinated turn close to stall speed for a non-NG DA40. It also excludes the startle/denial delay. The altitude loss rates are sort of extrapolated from the bast-glide loss rate, though the 60-Kt numb...

Re: Engine failure best glide speed descent rate

The EAA just had a great webinar that covered this topic. It's amusing that it took all this analysis to realize a disqualifying criteria for whether you could make it back: The angle of climb vs. your best glide angle. If you climb at an equal or more shallow angle than your best glide angle, you ...

Re: ELT testing

I can't get overly excited about testing every possible function. It only proves that it works that time, that day. I monitor the Aviation Safety Network for various kinds of accidents. Inevitably they have a link to FlightAware that, low and behold, shows the flight termination within a mile. In ad...

Re: Engine failure best glide speed descent rate

And remember that a 180 turn will make a loss of 500ft Thanks for the input, but that number doesn’t seem to match what was mentioned previously as 838 ft/min gliding with propeller windmilling and 713 ft/min with propeller fully stopped. Considering the standard turn will last one minute. What cou...

Re: Question about the backup battery.

If you replace the backup AI with a GI-275, then why do you need the floodlight? The GI-275 has AI, Airspeed and Altimeter and it's own lighting. Does anyone know what the backup battery weighs? My perspective, given the configuration of my plane. I find when I fly at night I always have the floodl...

Re: Seeking advice on control stick "notch" in center and other MX issues.

Gentlemen, thank you for your fast and informative responses. I worded that original description of the emergency side window fix the wrong way: Actually, the fix was to use heat to dissolve the adhesive holding the side window on, and then use adhesive (I assume Acrifix or similar) to re-glue. -Pe...
