Fuel Level Sensor

The fuel level sensor is mounted in the fuel tank and consists
of a float device guided by a rod. This rod provides a variable
resistance to ground which is communicated to the ground
module, which in turn, communicates the information to the
operator by way of the fuel level indicator on the platform
console and the low fuel indicator on the ground console.
