Peter,
Granted this transponder does have an automatic STBY/ON and visa-versa switching ability, but upon landing it does not seem to switch quickly enough to prevent the erroneous traffic alerts. You can adjust that. There is a timeout after which it will go to GND mode after the speed falls below the threshold speed (30 knots is default, I think). The default delay is 30 seconds, I think, giving you time to taxi off the runway. But you can set that to zero. Google for the 330 set-up manual if you don't have it. -- Thomas Borchert (EDDH) |

"Robert M. Gary" wrote in message oups.com... I think that is a myth. I don't think the computer shows ATC your signal if your altitude shows you at ground level. It's not a myth. The computer doesn't know where the ground is, it filters out only whatever it's told to filter out. |

"Orval Fairbairn" wrote in message news I set to "Standby" on the ground, to prevent reflections that could damage the unit. What reflections would do that and how? |

I will look into changing this value. -- Peter ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

I was taught to switch from standby upon starting to roll down the runway for departure. You were taught to mess with non-essential stuff on the runway? I once flew with an VFR pilot - he wanted to see what IMC was like - it was a great flight (lots of IMC) and he did amazingly well in the clouds - I was impressed. I let him land - right after we touched down, his hands were moving around the panel so fast I finally just slapped his hands hands and said "Stop! Do that when we're stopped on a taxiway." Hilton |

I was taught the old "lights, camera, action" deal. When I'm preparing to
cross the hold line onto the active runway on goes the landing light, and the xpndr to Mode C from Stby. When I cross the hold line after landing .. it's Xpndr to Stby, landing light off (unless it's nite), and electric fuel pump off. .. "Maule Driver" wrote in message .. . I don't. It stays on 24/7 (you know what I mean). 1200 unless given a code. It effectively prevents "Maule, check your transponder" unless using the wrong code. I make no attempt to turn it off or go to standby while taxiing or anything else. I've never been asked to go to standby or otherwise questioned. This has been discussed before but I'd suggest the everyone can do this without causing a problem for anyone. |

I'm not sure I'd characterize it as "non-essential." I was taught the "Lights, Camera, Action" reminder phrase where 'camera' signifies transponder on. This mantra is to be uttered in the beginning of the takeoff roll. Lights: strobe, landing lights, etc. Camera: transponder Action: mixture, props, throttle, airspeed alive, ...

Thomas Borchert wrote: Orval, I set to "Standby" on the ground, to prevent reflections that could damage the unit. Say again? Or rather, explain that, please. Most TXP antennae are belly-mounted. They send out a rather strong EM signal that can reflect off the pavement and overwhelm the receiver portion of the TXP, possibly damaging it. |

The reasoning that was cited had to do with radar clutter on the airport surface. ADS-B may change this practice, however. The change was made eons ago. There's no reason to turn the transponder to STBY anymore. |
