dvv...good form!
I should have known someone in DC would know...
considering how many aerodromes they have, thats is very low, is this due to tech upgrades?
I know they have many GBAS systems shown, with GBAS final approach procedures, but am not aware how many of the aircraft are GBAS equipped to take advantage of this...
do you know of the operability of the GBAS/aircraft procedures?
