Radar Operations:


Currently there is no primary or secondary radar radar in Luanda FIR. So do not carry out operations of separation and radar vectoring, and the position of traffic in IVAC maintained only for monitoring.
As a result should not be assigned SSR code "discrete", ie unique code for each aircraft. Instead it may be assigned a unique "non-discrete" in the case of the 1000 and withdraw options IVAC the "squawk code duplicate check" Menu PVD / Label Route Options. That way you can see the entire label traffic without assigning a "discrete" SSR code in NRA (Non Radar Airspace) which would be unrealistic.


Vertical Separation

  • The altitudes in route within the FIR Luanda are under rule Semi-circular. Means traffic that flies between 0 and 179 degrees will have to fly an "odd level" (eg FL190, 210, 230, etc..) And between 180 to 359 degrees one "event level" (eg FL180, 200, 220 , etc.)..
  • Above FL290, entered into the space RVSM (Reduced vertical separation minima). The separation continues as above with the exception of space Oceanic AORRA. Between FL290 and FL410 is eapaço RVSM. After FL410 ceases to exist and the RVSM separation passes for 4,000 feet between levels.
  • The VFR traffic crossing above 3000 feet MSL follows the same rule adding 500 feet. (e.g. 3,500, 5,500, 7,500, etc.).. The highest level of flight to VFR traffic is FL 195.
  • To operate in RVSM airspace the aircraft must be certified to do so and include the letter W in field 10A Flight Plan. Otherwise should remain vertical separation of 2000 feet.

Longitudinal Separation


The longitudinal separation usually applied in Luanda FIR within the same flight level and the same course is 20 minutes. The minimum longitudinal separation between jet aircraft flying in the same direction and level flight is 10 minutes if traffic ahead hold a speed equal to or superior to that above, or:

  • 9 minutes if traffic ahead hold a speed Mach 0.02 faster than the above.
  • 8 minutes if traffic ahead hold a speed Mach 0.03 faster than the above.
  • 7 minutes if traffic ahead hold a speed Mach 0.04 faster than the above.
  • 6 minutes if traffic ahead hold a speed Mach 0.05 faster than the above.
  • 5 minutes if traffic ahead hold a speed Mach 0.06 faster than the above.

Reporting Positions

  • On routes defined by significant points , position reporting should be made on , and as soon as possible after passing through each compulsory reporting point . Positions reporting information may be requested by the ATS unit when deemed necessary for air traffic service .
  • In route that are not defined by dots significant positions reporting should be made as soon as possible after half an hour of flight and then at intervals of one hour.
  • Contents of positions reporting:
  • Aircraft identification
  • Position
  • Time ( Zulu time)
  • Flight Level
  • Next position and estimated time
  • Next Position


VFR aircraft will come into contact with the control unit allocated according to the following procedures :

 

  • As soon as possible after takeoff
  • When changing frequency
  • With the target in sight
  • On long-haul flights a position reporting should be fair at intervals not exceeding one hour.
  • Takeoff Separation
  • When necessary the matches sequenced, the controller responsible should take into consideration the following times:
  • 5 minutes if traffic involved to follow suit after takeoff.
  • 2 minutes if traffic is followed at least 40kts faster than the follower.
  • 1 minute if the course will soon diverge off at least 45 degrees.
