French air traffic regulations conform with the recommended standards and practices specified in Appendices 2 and 11 of the Chicago Convention.
VFR flights manoeuvring within New Caledonia FIR are not provided with an air traffic control service. Flight information and alert services are provided wherever possible.
Permanent frequency monitoring is required for all IFR flights manoeuvring within the New Caledonia FIR.
The flight information service provides pilots in command with information concerning weather conditions, infrastructure and known traffic.
Unless a contrary clearance is give within class D airspace, an IFR or VFR flight is limited to 250KT below 10000FT.SPECIAL VFR FLIGHTS
A special VFR clearance is necessary to enter or manoeuvre in an aerodrome control zone, when indicated ground visibility is less than 5KM or ceiling is below 450M (1500FT).
IFR flights outside controlled airspace, where no minimum level is specified, must operate at a level 300M (1000FT) above the highest obstacle located within a radius of 8 KM around the estimated position of the aircraft. This value is set to 600M (2000FT) in hilly or mountainous areas.VMC CLEARANCE
On request, an aircraft in IFR flight manoeuvring at day time in VMC may obtain an additional clearance “VMC" clearance.
Such a clearance allows it to continue its flight in VMC, freed from statutory spacing, while visually ensuring its own spacing with regard to all other aircraft in IFR flight.
It can also relieve it from preset routes.
A VMC clearance:
a. is valid only for a predetermined part of the flight;
b. can be issued only within class D or E controlled airspace;
c. cannot be issued to an aircraft to perform an approach procedure.
When an aircraft has obtained a VMC clearance, it must: a. warn the appropriate air traffic control organisation as soon as it observes degradations in meteorological conditio ns likely to prevent continuation of flight in VMC; b. obtain an additional clearance prior to IMC flight. 2.6 When provided with a VMC clearance, the pilot must manoeuvre in order to avoid any incident due to trailing vortex: a. generated due to own trailing vortex; b. by considering the trailing vortex of other aircraft.
Within the New Caledonia QNH area, at 11000FT and below, aircraft must express their vertical position in reference to Tontouta QNH, except for aircraft taking off, landing or manoeuvring within an aerodrome control area where the aerodrome local QNH is to be used.
The transition layer between 11000FT and FL130 can only be used for climb or descent operations. When crossing the transition layer, during descent, the vertical position of the aircraft is expressed in altitude (QNH setting).
Within the New Caledonia QNH area, if the altimeter setting cannot be obtained prior to departure, the pilot in command must set the altimeter with regard to the aerodrome altitude and request communication of the altimeter setting as early as possible and in any case before entering IMC conditions.
The New Caledonia OCA Class D airspace extends from 9500FT to FL195. Class A airspace extends from FL195 to FL245. Nadi OCA Class A airspace overlays the New Caledonia Sector up to FL600.TMA
