The Scoop on Fuel Scooping
As with much of Elite Dangerous, Fuel Scooping is a series of compromises.
Should I fast scoop or slow, should I buy a small scoop or a large, the cheapest or most the most expensive.
Based upon experience, the following are my conclusions:
Tactically, fast scooping is the safest option, many of the dregs of ED pond life hang around the stars (suns) looking for easy kills and to commit acts of piracy, so a slow moving ship is an inviting target for interdiction, avoidance of which can result in your getting too close. Secondly a fast scoop leaves you less likely to burn. The sun puts out heat in the form of radiation and the protection against radiation is based upon 3 factors, time, shielding and distance, the faster you go the less time you are exposed, the less time exposed, the closer you can get, the closer you get, the less time needed to scoop maximum fuel.
If your style of play is based on trading, then economically, the bigger the ship, the more you can earn therefore, a large scoop is taking up cargo space, so this is a compromise you need to work out. If you fly short hops on planned routes, a small scoop might provide a safety net (though, never forget that in the event of running out of or short of fuel, if you have a good supply of elements, you can use synthesis to manufacture a shot of FSD Injection to give yourself an extra bit of range). If you are doing longer journeys on a regular basis, then a scoop is a necessity, to my mind, the larger and higher the class, the better. A 7A scoop will allow a fuel collection rate in excess of 1,200 units/second. Though it costs in excess of 28,000,000 CR and 128 units of cargo space.
In order to scoop fast and safely, I would recommend the following:
Always have orbit lines on, this will provide a visual queue (the green line around the sun) identifying how close you can approach without suffering an FSD failure.
When approaching the point at which you may receive damage from the sun's heat, the “Hologram” of the sun, on the cockpit display, turns red, this is an indication, but there is a degree of leeway beyond this that you can use.
Find a reference spot on your canopy bow or frame which allows a heat build up of maximum of 65% and base your speed on maintaining a constant position w.r.t. the green line to achieve the 65%. It is not difficult but the size and agility of your ship will determine how fast you can go. My Anaconda cannot maintain a tight circle around a small diameter sun, without a reduction in speed, so, another compromise, as suns are not all constant sizes. If your ship is agile enough to maintain max velocity, then use it. It takes a little (not much) practice. I usually find that where (as in most cases) your next jump is on the opposite side of the sun, the fuel used on the previous jump can be scooped in travelling half of the circumference of the sun, and by the time you are lined up on your next jump destination, you tank is full again.
