Ivan Urge - The FAA's
Departure Procedure Program (Order No. 8260.46) has the following WRT terminology to be used in SIDs:
(1) When required, departure instructions should specify the actual heading to be flown after takeoff. Example: "Climb via heading 350... " Some existing procedures specify "Climb runway heading." Over time, these procedures will be updated, changing the terminology to specify the actual heading being flown.
And:
Runway Heading. The magnetic direction that corresponds with the runway centerline extended, not the painted runway numbers on the runway. Pilots cleared to "fly or maintain runway heading" are expected to fly or maintain the heading that corresponds with the extended centerline of the departure runway (until otherwise instructed by ATC), and are not to apply drift correction; e.g., RWY 4, actual magnetic heading of the runway centerline 044°, fly 044°.
So are there countries other than Japan that do it differently? And why?
