I'm reading up on crossing the Atlantic and fly from Canada to the UK.
Lots of info online, and most (unofficial) sources claim that you need an HF radio if you fly from Goose Bay to Greenland. If you go via Iqaluit, you don't need it.
This caused me to try and find some official info, which seems surprisingly hard.
I found this file: https://tc.canada.ca/sites/default/file ... _e_nat.pdf
The last paragraph states (my emphasis):
So the bold part basically confirms the online info: Iqaluit - Stromfjord is fine, Goose Bay - Greenland, not really, unless you are above FL250.Several attempts to establish communication may be necessary
upon entry into the fringe area of reception. Aircraft should
maintain SELCAL watch on HF when in fringe areas of VHF
coverage. Upon exiting, communication should be re-established
on HF channels, preferably before flying beyond normal VHF
coverage. Because VHF coverage is limited, aircraft must be
equipped with an approved and serviceable HF radio capable
of two-way radio communication with ATS from any point along
the route during flight (see CAR 602.39).
NOTE:
Notwithstanding the foregoing, aircraft may proceed across the
Atlantic without HF radio subject to the following restrictions:
a) bel ow FL 195, routing Iqaluit (Frobay) – Sondre Stromfjord
– Keflavík; and
b) FL 250 or above, routing Goose VOR – Prins Christian Sund
(or Narsarsuaq) – Keflavík. The aircraft is not allowed to
operate in the NAT HLA unless MNPS authority is held.
Then I tried to track down where those restrictions were coming from. The underlined part kindly referred to CAR 602.39, which states (my emphasis):
Which leads me to believe that a light twin that is capable of maintaining altitude on one engine does not need an HF radio to crass Atlantic Airspace.Transoceanic Flight
602.39 No pilot-in-command of a single-engined aircraft, or of a multi-engined aircraft that would be unable to maintain flight in the event of the failure of any engine, shall commence a flight that will leave Canadian Domestic Airspace and enter airspace over the high seas unless
(a) the pilot-in-command holds a pilot licence endorsed with an instrument rating;
(b) the aircraft is equipped with
(i) the equipment referred to in section 605.18,
(ii) a high frequency radio capable of transmitting and receiving on a minimum of two appropriate international air-ground general purpose frequencies, and
(iii) hypothermia protection for each person on board; and
(c) the aircraft carries sufficient fuel to meet the requirements of section 602.88 and, in addition, carries contingency fuel equal to at least 10 per cent of the fuel required pursuant to section 602.88 to complete the flight to the aerodrome of destination.
Is that correct? Has anyone done this? Thoughts?
