When you go into a missed approach hold it does go into SUSPEND and remains there "forever" until you decide to leave the hold. Are we speaking of the same thing? In the 480 you tell it to hold, give it the turn direction, leg length etc and it flys the hold. I've not seen that in any other GPS product. The positive course guidance in a 400/500W is dependent upon having a roll steering autopilot. I doubt your 182 has a roll steering autopilot. Yes, the 182T does. Its not even 1 year old yet. It has a nice KAP140 autopilot. Totally hands off. Flys a full ILS down to minimums w/o touching it. The only thing it doesn't do is fly the hold. -Robert |

No, I think you are speaking of holds not in the database. Sounds like the 480 does a nice job of that. I am speaking of charted approach chart holds.

Did this change in the 430 with WAAS? From my teaching in the 430 and G1000 when you cross the holding fix it just goes into suspend mode (with a suggested entry procedure). The 480 actually figures the entry procedure and flys it, you never touch the yoke. Does the 430 WAAS unit fly the entry procedure? -Robert |

That's a motivation to upgrade the G1000 to WAAS. However, I just read somewhere that the rumor is that the WAAS G1000 systems will not drive VNAV to the KAP140. So you won't be able to fly fully coupled VNAV approachs with the KAP140 (even though you can fly a fully coupled ILS with it). Not sure what the techical limitation is but Garmin's solution is to upgrade to their Garmin autopilot (which I don't believe is certified for many applications yet). However, that will fix the issue of having to set the barometer 3 times (G1000, KAP140, standby alttitude) since the Garmin autopilot will take the baro setting from the G1000 directly. -Robert |

If an LNAV approach has VNAV minimums will you be able to use DA or will you have to use the MDA concept? |

It is more common than you think, assuming you routinely fly IFR to uncontrolled airports (at least in the Northeast US). While certainly not a lot, I have been asked twice over the year I was commuting to Dunkirk, NY, to momentarily hold due to another IFR aircraft ahead of me flying the approach. Additionally, on frequency I have heard holding instructions go out to every aircraft (air carriers and GA alike) approaching the big three NY airports when a line of t-storms was about to move through. The point being that the more you fly IFR, the more likely you will encounter a request to hold. -- Peter |

Holding west of Boston is very common, too. |
