zetato - I am out of touch with the latest FMC updates, but on the 737 I understood it always used to calculate a TOD, as NSEU says, with a coded ICAO destination on Routes to arrive at 1500' above the airfield. As you are aware, however, it is not normal to have just the ICAO as DEST - normally at least a runway would be entered which would give you a ball park TOD (or just take 25 mins off ETA
)
