My flight instructor is quite upset. He says every single one recurrent
pilots is making the same potentially fatal mistake. When they reach MDA or the MAP, they hit the OBS/SUSP button as soon as it lights up. The Garmin 530 immediately paints a magenta line to the hold waypoint. Unfortunately, often the full approach plate lists specific altitudes to which to climb before making this turn. The instructor says eight out of eight of his recurrent pilots are just hitting the SUSP button as soon as it appears and heading to the hold, which could take them smack dab into terrain or towers. We look up in the Garmin manual and it says nothing about making sure to reach the proper altitude before hitting the OBS/Susp button. His point is this: Garmin should have some type of display message that warns the pilot to reach the proper altitude before turning to the hold fix. |

Yeah, Seems like I remember the King Manual (KLN-94) pointing out that this is SPECIFICALLY why it doesn't autosequence to the holding fix, and that you should follow instructions off the paper approach plate before resuming... -- Cheers, John Clonts Temple, Texas N7NZ |

I mean with all the Garmin resources how hard can it be to fix this? I still
can't believe my Garmin 530 has no airways or altitude guidance on approach. I called the Garmin tech support line and they said, "Nobody uses victor airways anymore. Everybody flies direct." Gimme a break. Obviously they have never flow around DC, New York, Chicago, etc. When the approach segments come up, the screen should say "At or above xxxx." Jeez. I hope the upgrade makes some amends. "John Clonts" wrote in message ... "Wyatt Emmerich" wrote in message ... My flight instructor is quite upset.

![]() I see your point clearly. However, it appears to me that you want the GPS to do a bit too much for you. Remember, it is still your responsibility as the pilot of the aircraft to fly the procedure as published. Do you suppose if the GPS told you everything you need to know about the approach to fly it safely you'd be less reliant on the approach plate? I do, and I am not certain that's a good thing. Lynne |

But the GPS shouldn't suggest that you fly into a tower or terrain. Which is
what it does now. As soon as you pass the MAP point, the SUSP button starts to blink, begging the pilot to press it and fly to the hold. What the SUSP should do is blink with the additional message, "no turn until xxxx altitude." Come one. How difficult is that to program? Given Garmin's dominant position as an IFR GPS, it's not too much to expect. "Lynne" wrote in message ups.com... I see your point clearly.

It is the way it is because it is part of the TSO.

I'd a very similar conversation with Garmin tech support when researching the WAAS upgrade. I too asked about flightplan entry via airways (as the 480 does). The reply I received is that they thought it too much more complex for pilots. Why can't they just come out and say "we don't feel like it; what are you going to do about it?" At least that would be honest. A local FBO is upgrading one of their 182s with a 480. It'll be at least $25/hour more expensive than my club's 430-carrying R182 (and even more than our 430-carrying 182), but I need to try it at least once if only just for the flight plan entry. - Andrew |

Seems to me the error is on the part of the pilot, not the avionics. Is it really a fatal mistake to hit the SUSP button too soon? Just because you hit the button doesn't mean you aren't going to follow the correct missed approach procedure. Hit the button, climb to the required altitude, then proceed to the MAP. Maybe you have to punch DIRECT when you reach the altitude. The GNS480 (and maybe all TSO 146 navigators, I don't know) have the concept of a leg that terminates at an altitude, which will be the first leg of such a missed approach procedure. Dave |

How is that displayed on the map? Does the map automatically shift the next leg to "direct to the next waypoint" from the location at which the altitude is reached? What waypoint is displayed in the climbing leg? This sounds like an incredibly useful feature. There's a departure procedure at KTEB that's even more complex than this. From runways 1 and 6, this feature would cover it. But from 19, the procedure is runway heading until 800, then right to 280. Maintain 1500 until crossing the TEB R-250 & passing TEB 2.5 DME, then climb to 2000. Note the "TEB R-250 & passing TEB 2.5 DME" "waypoint". Can the 480 handle this? - Andrew |

Sorry, I don't have time to check on this right now, but maybe you can answer this question with the information from the references above. I'll try to look at this later. Dave |
