Can FLARM disturb TAS signal ?

@Wigglyamp
I forgot to ask about the temp probe which will be just close :-D

@wigglyamp
Actually, double blade upside is what I am accustomed to on the C182. It was designed that way by Cessna, to install (via SB) the KTA870.

That’s copied about Flarm / GPS interference.
In my case, would you fear interference ?

FLARM would be much less close than in you case (red circle)

One thing you might have spotted in the TAS antenna installation in post 8 is that the top and bottom antennas have been swapped – dual blade is now the upper. This is sometimes done on helicopters to prevent fore-aft reflections from the main rotor transmission, bur not often seen on fixed-wing installations

The TAS antenna location is very important – see here.

We were certainly responsible for over 90 of the fleet, along with composite support from a well-known glider maintenance company

Would you install TAS and FLARM aerials in the same way as post#8 (I mean one next to the other, I m not discussing windscreen shading)

I think this would be OK – on this airframe there are challenges with suitable real-estate for antennas anyway due to the sliding canopy so not much can be placed on the upper rear fuselage. The bigger worry here would be if either interfered with the GPS antenna in the centre rather than the TAS and FLARM interfering with each other.

Would you sharing your insight on this ?

It’s the same with PowerFLARM. Having an approved minor mod (or STC) saves time for the installer even if the work can be done as a Standard Change.

No Form1 or CoC for the GAV868 but Minor Mod approval with extensive AML.. at extra cost.

Interesting piece.
