NO Slats.
The primary "mission objective" is to "vanish", as in "without a trace".
The primary "flight objective" is to not "get caught", or "get seen" or "stuf it up".
He "must" therefore remain "in the dark" to avoid visual detection by ships or aircraft AND for him to be able to see the lights of ships, if any, because he doesn't want to ditch anywhere near one for obvious reasons.
For that and other reason, (many others), he "must" "overfly" his "intended ditch zone" in the dark, with him also "still in the dark".
He absolutely MUST remain in the dark, west of the terminator, until the last moments.
Remember that the terminator is actual sunrise AT THE SURFACE, it is NOT FIRST LIGHT OF DAWN, ie, after BOD, he is flying at low level in TWILIGHT. There is still the risk of detection even from a yacht that might not have been showing running lights, or with lights so dim, that he had not seen them. He has to "minimise" the "risk" of visual detection at all costs.
Remember, that the earth rotates 15 degrees longitude per hour, or a degree every 4 minutes. At 30 degrees south, a degree of longitude is 60nm x Cos(30) = 60 x 0.866 = 51.96nm. So, the terminator is moving west at 51.96 x 15 = 780 knots.
Flight speed is 480 knots.
If at any point he is too far west, he can turn east (actually to true course 097) and go straight at the advancing terminator, closing speed 780 + 480 = 1,260 knots.
If he was too far east, he could not "run away" from the terminator (only Concorde, or supersonic mil-jets could). Even if he headed 277 true, it would be catching him up at 780 - 480 = 300 knots.
Therefore, he "must" REMAIN WEST OF THE TERMINATOR AT ALL TIMES.
For simplicity, consider the green track as a long extended "down-wind leg" of a left circuit. When he reaches 2,000 ft RA, he is effectively ready to make the "left base" turn (ie, to head east-ish) and then a few minutes later (now in twilight which is getting more "lighter" by the minute, he "turns final" to the nnw.
The "descent track", (ie, the green track) must allow him to "clear the ditch zone" and place him in a position for "maneouvering" for the actual ditch, whilst in twilight, so that he is ready to actually "drop it in" as soon as "his sun" actually rises, and he has full light, and thus a useable shadow (critical requirement) for the actual alighting.
As for the fuel issues, yes, as you say, my plan accounts for that, ie, running parallel to the terminator earlier, if needed. In fact, any time after crossing it (at 12 degrees south).
