Hey guys, I'm planning my first trans Atlantic trip from London to Gander and was wondering if I could pick up any tips from the captains who've done it before.
Like whats the best altitude, roughly what fuel to plan to take etc. I'm going to head out over Ireland and use two radio beacon ships to navigate by.
I think I've thought of everything but that little bit of self doubt is creeping in on whether I've forgotten anything. Also I am planning on servicing the engines
before we set off, just in case.

Thanks for any guidance in advance.
Cheers
S.

PS. I'm using COTS so I'm hoping the flight engineer will be up to the task of a long trip.

It all depends on the day, and the weather. I personally have yet to cross the Atlantic in the Stratocruiser (an engine fire and prop pitch loss both contributed to turning around twice), but have done it in other jets. I have however, crossed every other ocean so far in my round-the-world flight, so I'm no stranger to the long, over-water operations. I have, so far, lost two engines over the ocean. Today, trans-atlantic tracks are created every day, to space all flights crossing the ocean. As you can see on the below pictures, trans-Atlantic tracks are plotted across the ocean, ensuring that there is 60 miles lateral spacing between aircraft, and thus planes fly at a range of altitudes on those tracks. Those tracks change daily, and are setup to, as I said, space out flights for the 60mi+ lateral distance, and offer the best route for the winds that day.

Tracks A and B are for the real long-range stuff like Salt Lake City, San Francisco and Los Angeles. C, D, E, and F are all for New England-Europe.

As you can see from the Upper Air weather, flying East to West on this particular day (this is from March 18) would have significant headwinds at FL300, which would normally be optimum for fuel consumption and long-range operations.

Gander is now an alternate on Trans-Atlantic flights, seeing that jets can do the whole thing non-stop. There are several alternates to keep in mind: Shannon (EINN), and Reykjavík (BIKF). Another airport exists, called Dyagilevo UUBD. It is a Russian base, with a 9,000ft runway and belongs to the Russian military. In an emergency (like two engines out) you could land there. Technically, Dyagilevo is in mainland Russia, but FSX has put it in the mid-atlantic, so you could land there, but going off the runway means falling 200ft into the ocean.

Good Luck!

Thanks for the info, to be honest I was wondering whether FSX actually put any significant weather/ winds over the big oceans.
I've come across other areas, Africa for example, where weather is almost non existant, at least on the ground. Lack of reporting and or
coverage I guess. I was however assuming the easterly direction would be more demanding on fuel than westerly.
Looks like I'll need some extra fuel just in case at least for this first adventure across the pond.

Thanks again PJC, especially for taking time to post those maps.

OK, I did it!!!

after 10 hours, 3 minutes I had touch down in La Guardia from EIDW Dublin

Image

As my company needs money urgently, we where full on passengers, so I had only about 90% of fuel.
But that lasts for La Guardia, however there was no safety amount of fuel.

I had real weather enabled (AS2012) and most time about 30 knots from front/left, a while 70 knots @ FL300.
Without the brilliant weathership gauge I'll have surely ended somewhere in greenland ...

It was an exciting experience (though I had time to clean our bathrooms meanwhile :wink: ), but something I don't do again for the next month ...


oh, I had no virtual Flight Engineer ...

Thanks to A2A for such a great addon!

Great job! My crossing, Shannon to Gander (which recreates the actual Pan Am routing) took 6 hours 42 minutes, with an average 53-knot headwind, and 70 passengers.

I've done many Atlantic crossings in a few aircraft with accusim. My most recent was from heathrow egll to JFK non stop. Done in 12+ hours. Average speed 253mph at 31k. With manual leaning you really can take charge of the fuel burn. I did have reserves with fuel stops along the way if needed. Ir gander Bangor etc if needed. Auto lean for true long range is too rich for me. I like extra fuel so I would sacrifice a few knot to save 100pph+ in fuel savings.
