Did you primer your ADSB box?

OK, not trying to be sarcastic or anything............well maybe, because its fun sometimes, but you did say ENGINE driven generator ya?

Yep, you can get by with a wind driven generator. See my last post.
BTW, They are NOT very efficient. They create a huge amount of drag.

Gliders have been using total-loss for decades, just size your battery appropriately and use deep-cycle batteries.

I'm no expert on this aspect of ADS-B, but I'm not sure the FAA really considers an electrical system a battery and generator when it comes to ADS-B:

91.225 (ADS-B):

The requirements of paragraph (b) of this section do not apply to any aircraft that was not originally certificated with an electrical system, or that has not subsequently been certified with such a system installed, including balloons and gliders.

A balloon and glider never have engine driven generators, yet still need ADS-B if they have electrical systems.

As a contrast, the transponder regs specifically mention engine driven, and specifically exempt gliders and balloons:

91.215:

(5) All aircraft except any aircraft which was not originally certificated with an engine-driven electrical system or which has not subsequently been certified with such a system installed, balloon, or glider—

Also, the FAA currently has an NPRM out on requiring transponders in gliders, removing the exception, so this may all change in 2017 anyway depending on what they do with the language:

https://www.federalregister.gov/arti...nt-for-gliders

All of this is moot if the FAA has another document that solidly designates the term "electrical system" as having an engine driven generator though.

I'll take that as a complement.

Or solar panels, which is what I plan on using.

My 1941 T-craft had a generator hung between the gear legs. It was added during the war to power the radio as it was a Sub spotter off of Long Island.

Ian, the proposed glider requirement won't apply to no-electrics airplanes, as of my last reading. Should a jet hit a Cub at high altitudes like one did a sail plane a few years back, that might change.

Ian,

Don't the two regs say the same thing, with just the language inverted?

The 1st quote says the reg *doesn't* apply to gliders, etc; the 2nd quote says the rule *applies* to everything *except* gliders, etc.

Might as well make all the drone pilots install ADSB so WE can see them on our PFDs

The drone industry is working on transponders and ADS-B out. The intent is to beat the FAA to the draw.

The Air Force comment to congress is just a move to get funding. The Air Force is equipping (I'm working some of the projects) but they just don't have the funds to do the entire fleet (so they say). Military airplanes are a bigger problem since they use IFF rather than commercial transponders typically. The equipment manufacturers are qualifying the IFF systems for ADS-B but with some really high cost associated since there are so few of them.

Transport airplanes are a more complex problem than small airplanes. Considerations extend to TCAS II and installing qualified position sources with antennas in pressurized aircraft.

I have ADS-B out and love the ADS-B in features. It is great having traffic with the flight ID associated with the traffic. Much easier to follow ATC call outs when you know which traffic on the display they are talking about.
