This is a 747 repeat of a cross Atlantic flight described in the third post in Donkas's 6th April thread Time-Lapse-Global-Flight

The navigation method and route is unchanged. I could not use the detailed plotted rhumb line live for fear of loosing the Aerofly flight through switching apps live.
San Francisco to Galway, near Clifden where the first non stop Atlantic flight landed in 1919. Leaving the North American west coast for the European west coast, Rhumb Line true heading 078 with an average estimated variation of 8 East as far as the start of the great lakes to give a magnetic heading to steer of 070 M.
Passing Yosemite and Mono lake, with average variation in use the track will vary due to higher or lower local variation, the local Hdg M to pass exactly north of Mono would have been 078 T minus 14 East to steer 068 M.
By Utah the scenery is gone. Maximum stable performance established after some creep up and zoom down to get Mach 0.954. Horizon at 33,000 feet is 213 miles away. A fuel burn 'how goes it' gives zero fuel used, less than expected.
Bland sandy scenery but is this a FAULT?
Moon setting, a chance for some bubble ***tant shots in the open cockpit Pitts or an old aircraft which has an astrodome. Maybe in the full sized version with independent add-ons. Would a Radio Range navigation (.- versus -. in the earphones) add-on in the full size version in a 40s or 50s airliner not be wonderful?
Hey IPACS what about it now in mobile? No need for any of those moving dials. Radio Range worked so well because only a cheap ordinary radio was needed.
Edit read (space added) se xtant shots
New average magnetic variation applied at the Great Lakes for as far as St Johns. 078 T plus 12 West for 090 M.

Various NDBs pop up but they all have the same 417 frequency so having the numbers on view does not help much. A single ILS appeared but with 3 mile wake-ups that would be expected.
Barrie and Toronto, about 20 miles north of intended track after 2000 miles with no nav aids or ground detail. About 1/2 a degree out. Got worse later.
NDB passing 2miles to starboard about 80 miles past Montreal must have been Victoriaville. Note the ident F8 .._. _ _ _..
Edit Only worked that out later, not live. Was afraid to look up charts in case swopping live apps killed the flight.
The planned track was south of the Iles de la Madeline in the Gulf of St Lawrence so I was about 60 miles out after another 1000 miles or 4 degrees! Must have underestimated the big variation bubble on the east coast.
Edit 1 degree out from SFO.
Correcting more to coast-out at St Johns Newfoundland.
St Johns. Last land for 1,600 very nautical miles. Full local variation of plus 18 west plus 2 of correction for 098 M.
Turning for 091 M, 078 T plus average Atlantic Ocean variation of 12 west plus 1 correction. Should have delayed the turn a bit.
Nice weather for the middle of the North Atlantic. Not much of a view.
