275, Neumayer III skiway, Antarctica via South Georgia and the South Sandwich Islands to Stanley, Falkland Islands
DAY05_23.PLN (1.8 KB)
Two long flights with an improvised refueling stop at Grytviken, South Georgia Island. (There are no airports on the entire island chain) The bay was already frozen, fine to land on and I had pre-ordered 80 gallons of fuel off Amazon to be delivered in port ahead of time

1:54 AM Departure time at Neumayer III
I had to put the plane on the ground first in slew mode, haven’t figured out yet how to start on the ground from a set of coordinates
Plane in the air pointed at Montagu Island, select full tank, time to catch some sleep
7,000ft 16.0% 2515rpm -1F IAS 111 TAS 121 GS 147 ETA (Montegu) 7:46 AM
I set the fuel mixture to 16%, 2515 rpm (prop 93%) which gave me an IAS of 111. GS 147 thanks to a strong half tailwind. Icing is a big risk of course so I set altitude far out of range (30K ft) and activated FLC mode to ‘climb’ at 111 knots, thus staying at the same level.
The idea is that if the plane ices up, FLC mode will lose altitude to maintain speed. Actually it tries to maintain the same altitude until the speed drops too low, then AP pushes the nose down to prevent a stall. It will do this in altitude hold mode as well, the difference is, in altitude hold mode it keeps trying to steeply climb back to the assigned altitude, causing worse and worse near stalls until you’re in the ocean. FLC mode stops climbing when speed drops below the assigned value. More stable, much higher chance at surviving the night while sleeping.
The other extreme happened, when I checked in early morning (6:45 AM) I found my plane at nearly 18,000ft. I guess as the plane got lighter (less fuel) it started gaining altitude. And by gaining altitude, the fuel mixture started getting closer to ‘power’ level. (Heavily leaned for 7,000ft). Thus the engine kept gaining power by climbing due to the plane getting lighter.
17,980ft 16.0% 2516rpm -20F IAS 111 TAS 147 GS 164 ETA (Montegu) 7:04 AM (ETE 22)
A lot faster higher up, also consumes more fuel though, I was just in time to switch tanks
Bristol Island up first, part of South Georgia and the South Sandwich Islands
Havfruen Peak (1,200ft) sticking out
Montagu Island, the largest of the South Sandwich Islands, British overseas territory
The island was first sighted by James Cook in 1775, and named after John Montagu, 4th Earl of Sandwich
The first recorded landing was made by the Norwegian whaler and explorer Carl Anton Larsen in 1908
Mount Belinda (4,490ft) is the highest peak on the island
Mount Belinda last erupted 2001-2007
Also a good spot for penguins to have a rest
Leaving Montagu behind, on to South Georgia Island
7,000ft 20.0% 2516rpm 22F IAS 146 TAS 162 GS 160 ETA (Grytviken) 9:51 AM
South Georgia and the South Sandwich Islands
Freezing up as winter season is here
Mount Carse (7,640ft) 2 nautical miles north of the head of Drygalski Fjord
Further over South Georgia Island
Vast colonies of king penguins breed in this broad cove, also home to elephant seals
Approaching Grytviken at King Edward Cove
Grytviken, used to be the largest whaling station on South Georgia
Flight time 8h31 Fuel used 67.78 gallongs, avg 150.2 knots ground speed, avg 18.87 nmpg
Gytviken is home to Sir Ernest Henry Shackleton’s grave (1874-1922) An Anglo-Irish Antarctic explorer who led three British expeditions to the Antarctic. He was one of the principal figures of the period known as the Heroic Age of Antarctic Exploration
South Georgia Museum, one of the most remote museums on the southern hemisphere
Taking off from Grytviken after filling up the tanks
Next stop, the Falkland Islands, 780nm from here
Queen Maud Bay and Mount Cunningham (4,000ft)
Leaving the main island behind
Bird Island where my right wing is pointing, the first island off the main island
Home to Bird Island Research station, nature preserve
Alastair Wilson uploaded a whole bunch of 360 degree views of this amazing place
12,000ft 30.0% 2440rpm 7F IAS 143 TAS 169 GS 196 ETA 2:02 PM
Safe between the layers of cloud, cruising to the Falkland Islands
Nearly there, kinda worried about icing while punching through the lower cloud layer
No problem, still ice free, not a thick layer either
Stanley, the capital of the Falkland Islands (Islas Malvinas)
The Falkland Islands are a self-governing British Overseas Territory, disputed by Argentina
Making a turn over Stanley to land at the airport
Enough flying for today, good place to start tomorrow

Tomorrow, back to Argentina after exploring the Falkland Islands. The long trip home has begun. 10,760 km to go, but I’ll make a lot of zigs and zags as usual on the way back up.
