[UI] A Few Words About the Flight Schedule

EOBT/TOBT can be used to indicate the estimated time of wheel chock removal (estimated pushback time)

ETOT can be used to indicate the estimated takeoff time

ELDT: Estimated Landing Time

EIBT: Estimated time to engage the wheel chocks

(The latter two are used less frequently)

(The EN interface can be modified; currently, EN displays "T Pushback" / "T Takeoff")
