TERMINAL. As described in facility directives, when vectoring a departing IFR
aircraft, or one executing a missed approach, when ISR is not displayed in the full data block and before it
reaches the minimum altitude for IFR operations if separation from prominent obstacles shown on the radar scope is
applied in accordance with one of the following:
The flight path is 3 miles or more from the obstacle and the aircraft is climbing to an altitude at least
1,000 feet above the obstacle, vector the aircraft to maintain at least 3 miles separation from the obstacle
until the aircraft reports leaving an altitude above the obstacle, or;
The flight path is less than 3 miles from the obstacle and the aircraft is climbing to an altitude at least
1,000 feet above the obstacle, vector the aircraft to increase lateral separation from the obstacle until the
3 mile minimum is achieved or until the aircraft reports leaving an altitude above the obstacle, or;
Radar facilities may vector aircraft below the MVA/MIA, provided:
(a) No prominent obstacles are within 10 NM of the departure end of runway (DER).
(b) Aircraft must be allowed an uninterrupted climb to meet the MVA/MIA within 10 NM of the DER.
NOTE: 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 if issued go-around
instructions, except after conducting a visual approach. ATC does not assume this responsibility when utilizing
a Diverse Vector Area (DVA) or when operating on SIDs with or without a published range of headings in the
departure route description.
After reaching the first MVA/MIA sector, all subsequent MVA/MIA sectors encountered must be met.
At those locations where diverse vector areas (DVA) have been established, radar facilities may vector aircraft
below the MVA/MIA within the DVA described in facility directives.
At those locations using radar SIDs, radar facilities may vector aircraft below the MVA/MIA, in accordance with
facility directives.
At locations that vector aircraft conducting a go-around or missed approach, use authorized headings and display
those prominent obstacles stipulated in facility directives until reaching the MVA/MIA.
