Where 310 fits
Why 310 is special
Eliminating the flight engineer was contested by unions and is now universal. The economics of a two-person crew rather than three changed airline cost structures permanently.

Read as powers of two: 256 + 32 + 16 + 4 + 2 = 310.
In historical numeral systems
Egyptian
3 coils of rope, 1 hobble
3 × 100 + 1 × 10 = 310. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 1 corner wedge (units place)
5 × 60 + 10 = 310. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then iota, marked as a numeral
tau-iota + keraia
tau + iota written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then yod
shin-yod
shin (300) + yod (10) = 310, written in descending order.
Maya
3 bars (upper, twenties place) over 2 bars (lower, units place)
15 × 20 + 10 = 310. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Technology & computing
The A310's two-crew cockpit removed the flight engineer from widebody operations. The change was fought and is now total, and it altered airline operating costs more than most airframe improvements did.
