In Range Checklist

This is an odd checklist that may take some creativity to use correctly. Your transition level will vary from as high as FL 190 to as low as FL30. We complicate things further by using altitudes for the other steps. I've found the checklist "Defer" option to be particularly useful here.

Everything here is from the references shown below, with a few comments in an alternate color.

 Procedure

[G450 Airplane Flight Manual §2-05-40]

1. Altimeters (3) . . . SET & CROSS-CHECKED (AT TRANSITION LEVEL)

   If you have a low altitude transition level, using the electronic checklist's "Defer" option can help remind you when the time comes to leave 1013.

2. SEAT BELT . . . AS REQUIRED

   Most operators use 10,000 feet to do this. Some have passengers who come up to the cockpit and say "Let me know when I really have to sit down," or who just ignore the thing altogether.

3. EXTERIOR LIGHTS . . . AS REQUIRED

   We get the pulse lights at FL180.

4. Flight Observer Seat Position / Interior Doors . . . CHECK
