Santa Maria Radar

SSR - Radar Services provided by Santa Maria ACC Radar Sector, following characteristics:
Radar Antenna position 365845.98N0250526.85W with operation coverage of 250NM/FL300.
Sector Callsign - Santa Maria Radar.
Sector Frequency 132.15 will be the main working frequency with 129.4MHz as backup.

The Following Minimum Horizontal Radar Separation will be applied:
- 10NM up to 100NM from Radar Antena and below FL245.
- 20NM elswhare within the radar service volume of 200NM, centred on Radar Antenna.

Within Santa Maria Radar Sector, vectoring will be provided above 5500FT expect within the area bounded by VFL, SOLGI, TIMTO, SOMUL, RODIL, VFL where the minimum vectoring flight level will be FL120

Within the area bounded by a circle whith 25nm radius centered in Santa Maria
Airport, vectoring will be provided above 3100FT (MSA)

Radar service applied to oceanic overflight along Santa Maria Terminal Area within 250NM centred on Radar Antenna.
All aircrafts overflying on the description area will be monitored by Santa Maria Radar on 132.150 and will receive a transponder code during overflight.
Beyond 250NM centred on Radar Antenna, the aircraft will be transferred to Santa Maria Oceanic.

The following requirements and procedures must be adopted by traffic within Santa Maria Radar Seector:

A - SSR Transponder Failure.

1) - Failure before intended departure:

in case of a tranponder which has failed and cannot be restored before    departure, pilots shall:
A) - Inform ATS as soon as  possible and preferably before submission of a flight plan.
B) - Plan to proceed as directly as possible,to the nearest suitable aerodrome where repair can be effected.
C) - Insert item of 10 of the Icao Flight plan form under SSR the letter N of complete unserviceability of the transponder or, in case of partial transponder failure, the character correcponding to the remaing transponder capability. 

2) - Failure during flight:
In case of a transponder failure during flight within or bound to enter Santa Maria Radar Sector, pilots may expect that ATC units will endeavour to provide for continuation of flight to destination in accordance with the flight plan. After landing, pilots shall make every effort to have the transponder restored to normal operation.
If repair cannot be effected, pilots shall comply with the above provisions for failure before intended departure.
The exemption from the requirement for transponder equipment mentioned in 1) and 2), may be granted by the supervisor on duty in the ACC whenever conditions permit. Change of ETD, Crusing Level and/or Route of flight may become necessary.

B - SRR Code Assignement.

Aircraft about to enter Santa Maria Radar Sector and haviong received code setting instructions from ATC, shall maintain that setting until otherwise instructed.
Aircraft shall acknowledge code setting instructions by read back.
All operations are reminded that in the NAT Region, outside of radar coverage, SSR Code 2000 should be set.
Aircraft immediatly prior to take-off run shall switch the transponder from Stand-By to ON.
Aircraft immediatly after landing, shall switch-off the transponder.
Aircraft without prior instructions may set transponder on mode A, Code:
A - 7500 In case of Unlawful Interference. Note, it is against the VATSIM code of conduct to declare a hijacking or squawk 7500
B - 7600 In case of Communications Failure
C - 7700 In case of Emergency.
