  • its a cockpit magnetic indicator showing the system status
    when the system is functioning normally — it will be black
    when the system is malfunctioning ——–it will be white or some annunciation(exit or off)
    Generally used in electrical and oxygen systems
    examples are DHC 6 Twin Otter( for the intake deflector ) ,Vulcan 607,Auro Vulcan………………………………
    the answer will be B, may be u also confused with C but it may show “white or annunciation flag”, not always white……but will DEFINITELY show black when the system is running or power is on…………………..happy learning n all the best
