1.Rules applicable to all IFR flights
 
1.1Aircraft equipment
 
Aircraft shall be equipped with suitable instruments and with navigation equipment appropriate to the route to be flown.
 
1.2Minimum altitudes
 
Except when it is necessary for take off and landing or when specifically authorized by the Department of Civil Aviation, an IFR flight shall be flown at an altitude that is not below the minimum flight altitude established and where no minimum flight altitude has been established:
 
  1. over high terrain or in the mountainous areas, at an altitude which is at least 2000 ft (600 m) above the highest obstacle located within 8 km of the estimated position of the aircraft;
  2. Elsewhere than as specified in a), at an altitude which is at least 1000 ft (300 m) above the highest obstacle located within 8 km of the estimated position of the aircraft.
 
Note. – The estimated position of the aircraft will take account of the navigational accuracy which can be achieved on the relevant route segment, having regards to the navigational facilities available on the ground and in the aircraft.
 
1.3Change from IFR flight to VFR flight
 
1.3.1 An aircraft electing to change the conduct of its flight from compliance with the instrument flight rules to compliance with the visual flight rules shall, if a flight plan was submitted, notify the Belize air traffic services unit specifically that the IFR flight is cancelled and communicate thereto the changes to be made to its current flight plan.
 
1.3.2 When an aircraft operating under instrument flight rules is flown in or encounters visual meteorological conditions, it shall not cancel its IFR flight unless it is anticipated, and intended, that the flight will be continued for a reasonable period of time in uninterrupted visual meteorological conditions.
 
1.4Operations of IFR flights within the TMA/CTR
 
1.4.1 All IFR flights inbound for landing at the Philip S.W. Goldson International Airport will arrange their descent to be descending through 4,000ft at Belize “BZE” DME 10 nm range, unless otherwise instructed.
 
1.4.2 All IFR flights departing from Philip S.W. Goldson International Airport will arrange their climb to achieve 4,000ft or above, at Belize “BZE” DME 10 nm range. Commanders of aircraft which cannot achieve the required climb gradient should inform the controller of the fact before taxiing so that he can arrange a special departure clearance.
 
2.Rules applicable to all IFR flights within controlled airspace
 
2.1 IFR flights shall comply with the provisions of 3.6 of ICAO Annex 2 to the Convention on International Civil Aviation when operated in controlled airspace.

3.Rules applicable to all IFR flights within uncontrolled airspace
 
3.1 IFR flights shall comply with the provisions of 3.6 of ICAO Annex 2 to the Convention on International Civil Aviation when operated in uncontrolled airspace as well.

3.3Position reports
 
An IFR flight operating within controlled and uncontrolled airspace when within the Belize FIR shall be required to:
 
  • submit a flight plan, and
  • maintain a listening watch on the appropriate radio frequency and establish two-way communication, as necessary, with the appropriate air traffic control unit.
 
Such aircraft shall report position as specified in 3.6.3 of ICAO Annex 2 for controlled flights.
