#define FLIGHTDATA_VERSION 117
// changelog:
// 110: initial BMS 4.33 version
// 111: added SysTest to LightBits3
// 112: added MCAnnounced to LightBits3
// 113: added AllLampBits2OnExceptCarapace to LightBits2 and AllLampBits3OnExceptCarapace to LightBits3
// 114: renamed WOW LightBit to ONGROUND, added "real" (AFM) WOW to LightBits3
// 115: renamed "real" WOW in MLGWOW, added NLGWOW
// 116: bitfields are now unsigned instead of signed
// 117: added ATF_Not_Engaged to LightBits3

// *** "FalconSharedMemoryArea" ***

    // GENERAL NOTE FOR ALL LIGHTBITS:
    //
    // The lightbits contain status about whether a lamp is activated or deactivated. A *blinking* lamp
    // is always activated, even if it is in the "off" phase of the blinking! To check whether an activated
    // lamp is blinking or just "on", use the BlinkBits in FlightData2. A blinkbit does NOT alternate on/off
    // either, it will just state *if* a lamp is blinking. This construct might seem strange at 1st sight,
    // but only like this it can be guaranteed that even low-freq shared mem readers will pick up the info
    // about blinking lamps correctly. Obviously, it is up to the external program to implement the actual
    // blinking logic/freq etc.
    //
    // Summary:
    // a) The LightBit says "lamp is active (LightBit 1) or inactive (LightBit 0)".
    // b) The BlinkBit says "if the lamp is active (see LightBit 1), is it steady (BlinkBit 0)
    //    or is it blinking (BlinkBit 1)"
    // c) If a lamp has no BlinkBit, it is always assumed to be steady if active (LightBit 1).
