Stealth mode in no way lessens the efficacy of FLARM anti-collision.

it is clear, and while your statement is probably technically

does exactly that. The OC fatality scenario is a case where stealth

You have not actually flown with PowerFlarm "radar", have you?

The amount of head down time required to develop any actionable

we'l=

ever become collision threats.

Read (I tire of saying this) the dataport spec. Page 19. It describes

th=

No, but I have flown with an LX800, not that this has anything to do with
it at all. I would rather take the advice of the makers of the instrument
and those who have been using FLARM for some time. Stealth mode is no
longer required here for competitions, the full mode can be used. FLARM are
very clear, "We do NOT recommend the use of stealth mode", which part of
that do you not understand. You ignore it at your peril or perhaps more
likely to the peril of others.
