It turned out to be the ADS-B out signal from that towplane. While I could silence the alarm by pushing the appropriate button, it came back after a minute or so. How are we going to deal with that when in a busy thermal with 10 other ADS-B out transmitting gliders? Doesn't Powerflarm filter out the spurious ADS-B proximity warnings when BOTH aircraft have Powerflarm (and 1+ aircraft have ADS-B-out)? Yes, that would require PowerFLARM in the tow plane. ADS-B alone is quite noisy. Jim Exactly. And been mentioned on r.a.s. in the past. PowerFLARM Out in the towplane if properly set up tells the other PowerFLARM units in the glider that the target is a towplane (no easy way to tell that over ADS-B), and a PowerFLARM equipped glider will deduplicate the target and use FLARM communicated data that provides better target flight path data. Not an issue for normal ADS-B GA traffic but other gliders and towplanes who will be flying close to PowerFLARM equipped gliders..... the implicit expectation is they have PowerFLARM Out.... which we don't seem to be actually installing in towplanes much in the USA. Folks putting ADS-B Out in a towplane for 2020 compliance reasons should be aware of this and thinking about adding PowerFLARM if they are towing lots of PowerFLARM equipped gliders. |

I made a request to LXNAV to add an option to silence the ADSB alarm for 10 minutes which is the length of a typical tow. If others will make such request they will probably consider this.

Ramy Are you asking them to silence all ADS-B alarms for 10 minutes, or just the N number of the tow plane? Silencing all alarms is a VERY bad idea, as there could be other GA aircraft in the area that could be a threat to the tow. A classic example is the midair over Boulder a number of years ago where a Cirrus hit a glider and/or aircraft during a tow. |

Powerflarm provides two type of alerts: traffic alert and collision alarm. The collision alarm is the most distracting one. I am asking them for a 10 minutes silence of the collision alalrm only. Ideally it would be for a particular aircraft but this would probably be too complicated to implement, so a 10 minutes silence is a good enough compromise in my opinion unless someone has other suggestions that can be implemented.

Ramy Ten minutes is a pretty good start! I'd prefer "permanently disable". Towplane or other glider ADS-B (without PowerFLARM) audible alarms seem to me like the many hotel fire alarms that have gone off at 2am. Jim |

Can't you just turn down the volume during the tow?Â* You shouldn't be
looking inside too much at that time, anyway.

Ramy, Thank you for this description. The ADS-B alarm is annoying on tow. My understanding is the warning is a result of an output from PowerFlarm to a display like LXNAV FlarmView or similar. Its the display that is doing audio annoyance. On FlarmView there is a 3 minute silence with a button push but I find when the alarm is sounding and the tug is identified as the target, I stop looking at the alarm as a real threat. The ten minute collision mute would be an improvement. Good idea to bring this up with the display manufacturers.

Dan, lowering the volume is an option but increase the chance you will forget to turn the volume back up. Also not all powerflarm displays have simple volume knob, some requires to go to the menu to reduce the volume.

Well, I guess it's a problem that I'm not very familiar with, then. I've
get maybe two or three audio warnings per year and am always surprised and gratified to hear them.Â* I suppose that's the difference between flying around Moriarty and Reno. I hope you find a solution that works for you. On 2/5/2019 11:58 PM, Ramy wrote: Dan, lowering the volume is an option but increase the chance you will forget to turn the volume back up.

What will the rules committee will have to say now that we can see ADS-B equiped gliders and their data on PowerFlarm at 20 to 30 NM. Richard The LX90xx manual describes the FLARM 'Dismiss Time' software button as programmable from 0 to 120 seconds. I'm not sure where this is programmed, but the default appears to be 1 minute. It would be nice if LX could add a 10 min Dismiss Time button; one that you could deselect would be a bonus. Charlie |
