Airspeed
Parsed multiplier on a country or a difficulty setting that no gameplay path reads.
The engine accepts and loads it, but no gameplay code uses the stored value.

Each country carries its own multiplier in its own section, and a house of that country combines it with the difficulty section’s and with GameSpeedBias once, at the moment it is given its difficulty slot. A campaign game drops the country’s contribution and keeps the other two, which is how Groundspeed= is treated as well.
What does set an aircraft’s speed is traced under the difficulty setting of the same name.

1The difficulty block is re-read from fixed defaults whenever its section is present, so a later file that carries the section without this key restores 1 rather than keeping the earlier value.- Used by the game

[Easy], [Normal] and [Difficult] each carry their own multiplier, and the one belonging to the slot a house is assigned is folded into an air-speed figure the house keeps, alongside GameSpeedBias and, outside a campaign game, the country’s own multiplier.
An aircraft in flight covers ground at its own type’s Speed= figure scaled by the throttle its flight locomotor is holding it at — a fraction that rises as it sets off and falls away as it closes on its destination — and no house figure is consulted anywhere in that step. The difficulty multiplier that does reach movement is Groundspeed=, and an aircraft in flight is one of the things it does not scale.
