Lusche made a list, but the search engine is draggin today.
What you do it type
.dt fxxfth and hit enter xx= the field number and must have at least two digits. So field A3 would be typed in as 03 (.dt f03fth) this will list the down times for all the FHs at that field, or it will say a objects are alive or something like that. Luschu list had all the short hand abbreviations. Lets see how many I have.
fth = FH
bmh = BHs
vhh = VHs
gng = guns
rdr = radar
bab = troops
If you add a 01, 02 and so on to the end you can get individual hanger/guns down times.
