Transoceanic Flights

GOTA, RVSM, CMNPS, SLOP... it looks like we're having Alphabet soup for lunch!

CAR 602.39 Transoceanic Flights
If you want to fly a single engine aircraft or multi-engine that cannot maintain flight in the event of an engine failure over the high seas:
  • pilot needs an instrument rating
  • aircraft equipped as per CAR 605.18 + HF radio + hypothermia protection for each person on board
  • sufficient fuel as per CAR 602.88 + additional 10%

Reference AIM RAC 11.0 North Atlantic Operations and ICAO NAT Doc 007

NAT MNPS = North Atlantic Minimum Navigation Performance Specifications
  • compliance with NAT MNPS airspace is required by all aircraft operating between 
    • FL285 and FL420 AND
    • between 27 N and the North Pole AND
    • Oceanic Control Areas: Reykjavik, Gander, New York, Shanwick, Santa Maria
  • aircraft must be equipped with two fully functioning long range navigation systems (LRNS).  A LRNS may be one of the following:
    • one Inertial Navigation System (INS)
    • one Global Navigation Satellite System (GNSS)
    • one navigation system using the inputs from one or more Inertial Reference System (IRS) or any other sensor system complying with the MNPS requirement.
  • for eastbound and westbound traffic
    • south of 70 N, the planned tracks shall be defined at each half or whole degree of latitude and each 10 degrees of longitude
    • north of 70 N, the planned tracks shall be defined at latitudes expressed in degrees/minutes and each 20 degrees of longitude
  • for northbound and southbound traffic
    • the planned tracks shall be defined at latitudes spaced at 5 degrees and whole degrees of longitude
