[NSRCA-discussion] No telemetry rule & new radio systems

[J N Hiller]

Yes, a blind and deaf person would definitely be at a disadvantage. Most of the time I can't hear my airplane at the club field and I don't see as well as I once did but I don't consider this an unfair disadvantage. This is still a skill based activity and no amount of technology short of a fully autonomous programmed UAV will totally replace it, in my opinion.
I will continue to monitor this discussion but will refrain from further comment.

If it was truly "closed loop" then you should be wearing a blindfold and have earplugs inserted. . .

"Closed Loop" ?? Dose this include information displayed for pilot and or caller to use during a competition flight? Or only electronic? If the info is displayed on the TX screen should it be blacked out during flight? A beep for low voltage is obviously a good thing but much more than that could be perceived as unequal advantage. Personally I don't have the time or processing ability to deal with it in real time. Keeping track of what I'm trying to do is about all I can manage.

“Good” and “No Good” are not the issue. As far as I am concerned, all information can be “Good”. The issue is how it is used – no closed loop control.

So, who's gonna draft a replacement rule for the old, antiquated one? Sounds to me like some types of telemetry are not a bad thing (airborne radio voltage, servo condition, are two OTOH). Other types are no good (direction, rpm, voltage/current of power supply, exhaust temp, etc)

They were removed in mine as well. That was the last Futaba top tier radio that came with good stiff springs.

I think we all know what the intent of the rule is, but I think we all agree that the rule needs to be modified to make that clear.
 
As for a snap switch, it is not a "control sequencing or control timing device" as it does not initiate any kind of sequence or start any kind of timing event, IMHO. Does anyone remember the very first Futaba 8SGA transmitters that DID have timers on the snap switch function, such that when you activated the switch it would deflect the different control surfaces for a predetermined amount of time (programmable). In my transmitter, the adjustment pots for that had been removed, presumably because of the rules against such functions.

I would speculate that the term "feedback" means a closed control loop where the telemetry data would actually become pre-programed data input to the TX software such that throttle, rates, flight conditions, or mixes would actually be modified by the software in real time. That would certainly be a game-changer! 
Just having open telemetry isn't an advantage...it's probably a distraction, unless you alarm on Rx battery voltage or something like that.
