Can someone let me know what the 2 numbers I have circled in RED on the IFD540 screen in the attached pic are (mean)? My assumption it has something to do with altitudes but I am guessing. Thanks for the help. ------------- Don |

Check the IFD540 PG Map pages section, page 3-8. Basically the split map display in the FMS section should be the same as described above for the Map pages. What seems a bit strange is that you should see 3 altitudes, 2 for the lowest and highest terrain on the map and the top one for obstacles clearance. All the screenshots in the FMS section of the PG show the 3 altitudes. Perhaps what you are seeing is somehow related to being a sim display. I notice that your GPS altitude is showing ---, so perhaps that is why the lower altitude is not being displayed. ------------- Vince |

The other thing that is puzzling, is that the top number should always be larger than the 2nd from the top, it can't be lower as it represents the higher elevation of an obstacle above the terrain. If they are the same, then these two are merged into one. There is no terrain scale drawn at all, nor a lower number. Perhaps terrain is not installed, or something? * Orest |

Can one configure the sim without terrain? ------------- Vince |

Definitely something weird there. I just tried it and the elevation showed 1000 to 1600 with the highest obstacle at 2000. I wouldn't expect it ever to look like your screenshot, but my guess is that it's something to do with the terrain database as has been suggested. Make sure you have North America terrain loaded. ------------- Steve Lindsley Avidyne Engineering |

I agree, the black background on the map display also may indicate a missing North American terrain database. |
