I flew the Sports Class Nats with Powerflarm Brick (v 3.0), Butterfly 57mm

display (v 3.1).



My experience last season was that flarm was a bit of a nuisance: in large

gaggles the darned thing made more noise than my audio vario. As well, I

found the "radar" tracking feature a useless distraction. So I thought I

would fly a contest with Stealth mode enabled by default as well as

Competition mode (higher alarm thresholds, enabled using the cflags

command in the configuration file, see the dataport specification for

details).



It all worked as intended. Warning threshold is "just right" for

competition use and overall distraction level is happily low.



The fraction of pilots at this contest using Flarm was happily high. I

heard "Thanks Flarm!" and similar on the radio many times.

Thanks, Evan, for your review of competition and stealth modes. I would like

to set my PowerFlarms to competition mode, but am unsure how to proceed.



The Data Port Specifications, version 6.00E, page 16, gives a value of

"0x02" to Enable Competition Mode, but the examples immediately below show

integer values. So, is the proper sub-sentence: $PFLAC,S,CFLAGS,0x02 or

$PFLAC,S,CFLAGS,2 or something else?



I am unwilling to experiment because it also says, "If you do not understand

the concept of bit flags, do not use this command!"



It is clear that the sub-sentence for stealth mode is: $PFLAC,S,PRIV,1

but I am not yet ready to try that.



Thanks in advance for your help in this. It would be nice if the PF folks

added these options to their web-based Configurator tool.

Hi Gary,

From my flarmcfg.txt file


################################################## ######################
# stealth & competition configuration
################################################## ######################

# set stealth mode on
$PFLAC,S,PRIV,1

# set competition mode (ON = 2, OFF = 0)
$PFLAC,S,CFLAGS,2



If flarm starts using other bits of cflags to manipulate other settings, then it will get a little more complicated. For now this should work.
