Even on pattern tows I go like hell to make sure I beat the glider to base and land well ahead of the glider. A few seconds can make a lot of difference in separation. C-182 better vis than a Pawnee? No way. Pawnee has better vis than ANY high wing towplane (I have towed in C-172s, Super Cubs, and Pawnees), especially in turns. But the real solution (as discussed later in the thread) is PowerFLARM in both gliders and towplanes. Kirk |

Glider releases, does a right 360° Tow plane does a left 360° I've seen this so many times. They end up back to the same spot. It is often taught this way. Neither plane can see the other until it's too late. Each plane should only do a 20° turn and the glider should be able to keep sight of the tow plane until it is well below the glider. When neither of the pilots can see the other plane, and they are both doing a 360° it is bound to end badly... We need to teach the glider pilots to keep an eye on the tow until it is below us. I don't know if this is what happened in this tragic accident, but it sounds like it might be the case? Boggs I agree we should teach the glider pilots to keep an eye on the towplane after release. The glider may do a 360 after release if in lift. But why would the towplane do a 360? At our club the towplane, after turning to the left, typically flies in a straight line until well away from the release point and thus hopefully from the glider. (Not implying anything about this specific tragic accident.) |

In this case, both glider and towplane were equipped with PowerFLARM.
I suspect this is the first North American midair between PowerFLARM equipped aircraft (notwithstanding the other midairs noted in this thread). Hopefully Transport Safety Board Canada will examine the PowerFLARM IGC recordings. We need to understand what went wrong. |

We certainly need to understand what went wrong and hopefully wouldnt need to wait 2 years for a final report to find out. If the midair happened soon after release then powerflarm wouldn't help as all it is doing is warning you of another aircraft which they already knew about. Powerflam is mostly effective when you dont expect traffic and it gets your attention. When you expect traffic such as in the pattern and in gaggles, powerflarm is much less effective as you end up mostly ignoring it and use "see and avoid". Ramy |

Ramy While PF is a big advance in flight safety, it is not perfect.

I would choose ADSB over PowerFlarm now, for a glider and a towplane.

I have a portable WAAS GPS and an obsolete cell phone running Avare to
display ADS-B In targets.Â* It does a better job than Flarm for ADS-B since I can see the targets on a current sectional chart in relation to my aircraft.Â* The targets display a flight vector and delta altitude.Â* Yesterday I had one of my compatriots displayed on different devices as a Flarm target and as an ADS-B target. But I have plenty of room in the cockpit for all these toys and my able wife to share the look out duties.

On tow, in a Pawnee I can clear my flight path better, especially in turns. On descent, I can crank it over and see below me just fine, without those high wings in the way. It does require care turning base to final when using opposite pattern from gliders - which I address with an angled final all the way to touchdown. But to each his own - important thing it to fly so as to maximize lookout. Cheers Kirk |
