IAS\"** (meaning: never fly faster than 206 knots indicated airspeed)\n- This must be done within **10 hours of flying time** after 8 July 1970\n\n**Why it matters:**\nThis directive was issued to prevent pilots from accidentally exceeding the aircraft's maximum safe speed (Vne — \"never exceed speed\"). Flying faster than this limit risks structural damage or loss of control.
