Garmin 530 WAAS?
"Sam Spade" wrote in message ... I don't see any need for air data to make this work. It is a positive course guidance oval, right? So, make the oval the correct dimensions for containment in protected airspace. Then, the autopilot, flight director, or hand-flying pilot will compensate for wind by simply remaining on the yellow brick road. My autopilot, S-Tec 55, won't do more than a 90% standard rate turn, and that is only in the high-gain capture mode. If you make the predefined oval large enough so that such a turn will get you rolled out on the inbound course in the presence of a stiff xwind from either side, I suppose you can make it work. For published holds, the containment airspace is already defined, and may be constrained in some areas due to adjacent airspace and ATC considerations. |

Restraintt of holding patterns for ATC purposes is very limited, the most common being using 210 knots in place of 230 knot patterns. |

So far as I know, although a lot of them used (and still do with the older birds) DME/DME updating, none of them used VOR/DME updating...well unless that was all that the system could see...and often it would just stay with IRU position rather than use a bad solution. Yes, airline FMSs are capable of VOR/DME and DME/DME updating, but you are correct that these modes don't get used much with GPS equipage. Mike |

I have read the GNS430W manual and didn't see anything about positive course
guidance around a hold. I may have skipped a few words. "Sam Spade" wrote in message ...
