FAQ
What do shuttle speed numbers mean?
Shuttles are graded 75 to 79 based on how far they fly when struck with a standardised test. 75 is the slowest, 79 the fastest. Most temperate-climate halls at sea level use 76 or 77.
How does temperature affect shuttle speed?
Cold air is denser and slows the shuttle, so you compensate with a faster (higher-numbered) shuttle. Warm air is less dense and speeds the shuttle up, so you use a slower (lower-numbered) one.
Does altitude really matter?
Yes — thinner air at altitude lets the shuttle travel further. Halls above 1500 metres typically need shuttles 1-2 grades slower than the same setup at sea level.
How do I know if my shuttle speed is wrong?
If full-power clears regularly land past the back tramline, your shuttle is too fast. If they consistently land short of the back service line, it is too slow. Two players exchanging full clears from back-line to back-line is the calibration target.
