"""Generates kneeboard pages relevant to the player's mission. The player kneeboard includes the following information: * Airfield (departure, arrival, divert) info. * Flight plan (waypoint numbers, names, altitudes). * Comm channels. * AWACS info. * Tanker info. * JTAC info. Things we should add: * Flight plan ToT and fuel ladder (current have neither available). * Support for planning an arrival/divert airfield separate from departure. * Mission package infrastructure to include information about the larger mission, i.e. information about the escort flight for a strike package. * Target information. Steerpoints, preplanned objectives, ToT, etc. For multiplayer missions, a kneeboard will be generated per flight. https://forums.eagle.ru/showthread.php?t=206360 claims that kneeboard pages can only be added per airframe, so PvP missions where each side have the same aircraft will be able to see the enemy's kneeboard for the same airframe.
