I would like to recommend a few suggestions on light usage. Most airlines seem to use the following.

 

Fixed Landing Light: On: When Entering a Runway, When Passing Through 18,000 MSL

                                 Off When Passing Through 18,000 FT MSL

 

Retractable Landing Lights: On: When Entering a Runway, and when slowing below 250 KTS

                                            Off: When Passing through 10,000 FT MSL

 

Runway Turnoff Lights:   On When Entering a Runway, When Descending Below 18,000 MSL at Night

                                       Off: When Passing through 18,000 FT MSL         

 

Logo and Wing Lights: On: At Night on ramp and Below 18,000 FT MSL

                                    Off: Above 18,000 MSL

 

 

Again these seem to be what most airlines use and 18,000 MSL seems standard, NOT 10,000 AGL

That's airline specific, but FYI, the upcoming 777 version has options to handle many of these types of variations.

 

The NGX already does to a degree as well.
