Before departure, assign the initial heading to be flown if a departing aircraft is to be vectored immediately after takeoff.
FLY RUNWAY HEADING.
TURN LEFT/RIGHT, HEADING (degrees).
1. TERMINAL. A purpose for the heading is not necessary, since pilots operating in a radar environment associate assigned headings with vectors to their planned route of flight.
2. ATC assumes responsibility for terrain and obstacle avoidance when IFR aircraft are below the minimum IFR altitude (MVA, MIA, MEA) and are taken off departure/missed approach procedures, or are issued go-around instructions, except when utilizing a Diverse Vector Area (DVA) with an aircraft departing from the surface.
Issue an altitude to maintain with the initial heading when the heading will take the aircraft off a departure procedure that contains both a published lateral path to a waypoint and crossing restrictions.
When conducting simultaneous parallel runway departures utilizing RNAV SIDs, advise aircraft of the initial fix/waypoint on the RNAV route.
RNAV to (fix/waypoint), RUNWAY (number), CLEARED FOR TAKEOFF.
“RNAV to MPASS, Runway Two-Six Left, cleared for takeoff.”
1. TERMINAL. A purpose for an initial waypoint advisory is not necessary since pilots associate this advisory with the flight path to their planned route of flight. Pilots must immediately advise ATC if a different RNAV SID is entered in the aircraft FMS.
2. The SID transition is not restated as it is contained in the ATC clearance.
3. Aircraft cleared via RNAV SIDs designed to begin with a vector to the initial waypoint are assigned a heading before departure.
