Anyone Own a Garmin GTX 327 Transp??
Our 327 is a few weeks old. According to the manual, the unit is
supposed to have Auto Mode switching from STBY to ALT on takeoff, and then back again on landing. The takeoff part works fine....as soon as the wheels leave the ground, the unit will switch to ALT and the timers will start. But it doesn't return to STBY on landing. That has to be done manually. I've fiddled with the Configuration Menu abit according to the manual and changed the Delay Timer to 0, but nothing seems to make a difference. What am I missing??? And I'm not sure what the Delay Timer is...is it in minutes? seconds? For what? I've posted a question to garmin.com but thought I would ask here as well. THanks!! --Jeff |

I have the GTX330, which has the same feature, and it also does not automatically return to standby at the conclusion of a flight. I haven't yet bothered to investigate the reason, so if you receive an answer on the Garmin forum, please post the reply here. -- Peter |

I've a fixed gear airplane (Cessna 182) so the switch from sby to active and back is done based on groundspeed. No problems so far, I've had this combo for two years now. -jav |

What am I missing??? And I'm not sure what the Delay Timer is...is it
in minutes? seconds? For what? Our 330 doesn't go to standby, but rather to a mode called GND for ground. Not quite sure what the difference is, but I think I have read somewhere it is a special mode S thing telling ATC you're on the ground. The delay timer is for you to still transmit an active transponder signal as logn as you are still on the runway, taxiing off it. Default is 30 seconds, I think. Of course, the automatic on function doesn't give you that option when taxiing onto the runway for take-off, something that bother me a little. -- Thomas Borchert (EDDH) |

Ray,
KPVD, for example requires the transponder be on while on any active part of the airport. "on" as in ALT? -- Thomas Borchert (EDDH) |

What I was recalling is that the TIS traffic call-outs occur while in GND mode (assuming at an airport providing TIS). To stop the call-outs while on the ground, I would hit the standby mode during taxi. This is where I was confusing my issue with the OP 's issue. -- Peter |

Garmin hasn't yet responded to my question posted to their customer
service site. Thanks for clarifying the purpose of the Delay Timer. It makes sense. I live in the Washington DC area and fly in the dreaded ADIZ. You must have a valid squawk before takeoff and have it on until wheels touch down. If you accidently hit 1200 before that, you get a not-so-friendly call from the TSA/FAA/FBI/CIA/NSA.... Pilots have been given warnings and lost tickets for all kinds of transponder glitches....mechanical and human. But enough of that!! My 327 is NOT linked to a panel GPS. So now I'm wondering how it knows you've landed to switch to STBY. A steady pressure altitude could mean straight and level flight! --Jeff |
