1. Purpose
  • MBZ's increase protection to aircraft in uncontrolled airspace
  • where high density or special operations occur. 
  • MBZ - lines of blue circular dots
2. Reporting
  • Broadcast position and intention reports
  • On entry, when joining a circuit, prior to entering a runway,
  • at regular specified intervals.
  • Landing and  anti-collision lights must be used if  fitted. 
3. Broadcast Content

  • is expressed with clock method
  • Each 5 minutes of the hour represents a
  • 30 degree arc 
2. Examples of use
  • Aircraft at 10 o'clock:
  • is at  2x30 = 60 deg
  • to left of nose of aircraft by left wing
  • Aircraft at 8 o'clock:   
  • is 4x30 =120 deg
