SUNSET AND SUNRISE− The mean solar times of

sunset and sunrise as published in the Nautical

Almanac, converted to local standard time for the

locality concerned. Within Alaska, the end of evening

civil twilight and the beginning of morning civil

twilight, as defined for each locality.
SUPER HIGH FREQUENCY− The frequency band

between 3 and 30 gigahertz (GHz). The elevation and

azimuth stations of the microwave landing system

operate  from  5031 MHz  to  5091 MHz  in  this

spectrum.
SUPPLEMENTAL WEATHER SERVICE

LOCATION− Airport facilities staffed with contract

personnel who take weather observations and

provide current local weather to pilots via telephone

or radio. (All other services are provided by the parent

FSS.)
SUPPS− Refers to ICAO Document 7030 Regional

Supplementary Procedures. SUPPS contain

procedures for each ICAO Region which are unique

to that Region and are not covered in the worldwide

provisions identified in the ICAO Air Navigation

Plan. Procedures contained in Chapter 8 are based in

part on those published in SUPPS.
SURFACE AREA− The airspace contained by the

lateral boundary of the Class B, C, D, or E airspace

designated for an airport that begins at the surface and

extends upward.

SURPIC− A description of surface vessels in the area

of a Search and Rescue incident including their

predicted positions and their characteristics.

SURVEILLANCE APPROACH− An instrument

approach wherein the air traffic controller issues

instructions, for pilot compliance, based on aircraft

position in relation to the final approach course

(azimuth), and the distance (range) from the end of

the runway as displayed on the controller’s radar

scope. The controller will provide recommended

altitudes on final approach if requested by the pilot.

(Refer to AIM.)

SYSTEM STRATEGIC NAVIGATION− Military

activity accomplished by navigating along a

preplanned route using internal aircraft systems to

maintain a desired track. This activity normally

requires a lateral route width of 10 NM and altitude

range of 1,000 feet to 6,000 feet AGL with some route

segments that permit terrain following.
