Andy,

SN10 supports:

T - Turnpoint
L - Landable (safe landing field, shows on Alternates page)
A - Airport (not necessarily landable)
S - Start point
F - Finish Point
M - Point of interest (Mark point?)

These can obviously be used in combinations; Turf, for example, is a
TLASF in my database. *OTOH, Luke 2 would be a TA and would not show
up as an alternate.

Thanks Kirk.

Actually Luke 2 is a bad example since in the current database it
shows as "LT" and it's actually half covered by a housing development
now. None of the Luke Aux fields are designated as airports.

I have heard of the SN10 assumption that airports are not landable
before, and I have to say it puzzles me. Why would anyone preparing a
database ever assign the "A" attribute to a place that is not
landable? Is this to cover the case where the government source lists
airports that don't exist anymore?
