| On the 10.3 trainer, when on an approach, a LSK on the FMS page will pop up a V with an Arrow through it, looks like the Direct button. What is this? |

That is a "vertical direct-to" function and it is part of the new enroute VNAV capability. The button appears when the cursor is on an altitude constraint field. When pressed, the IFD will compute a descent path from the aircraft position at that point down to the constraint altitude. It will then start providing deviations to that path. If you set up the trainer as a 550, you'll see the deviations on the SVS page. ------------- Steve Lindsley Avidyne Engineering |

| Aha, pretty cool. How will this work in a Cirrus with 2 x IFD440, DFC90 and Entegra? Would it actually couple to the advisory G/S? |

There's the rub. The IFD will output the deviations, but on a label that, while it is standard, is not typically consumed by some equipment. That includes the Entegra PFD and DFC90. Yet another reason I'm excited for Vantage... ------------- Steve Lindsley Avidyne Engineering |

Is this a promise?? I currently have VSR as an upper data block and find it very useful. VNAV will be another nice feature.

I'll probably regret this... Yes, I expect it to be supported in Vantage. ------------- Steve Lindsley Avidyne Engineering |

Steve, any chance to give us the label so we can check if our equipment supports it? I assume that by label you mean an Arinc 429 label used with EFIS like Sandel, etc.

Vertical deviation is on label 126 ------------- Steve Lindsley Avidyne Engineering |

Any particular reason for choosing label 126 for vertical deviation? The Sandel 3500 list of supported ARINC inputs indicates label 117 for GPS/FMS vertical deviation.

117 is used for approach deviations (ILS, SBAS). ------------- Steve Lindsley Avidyne Engineering |
