Minimum Performance Standard for Fuel and Oil Quantity Indicating System
Components
Description / Abstract:
This AS defines components in "Capacitance Sensor" and
"Non-Capacitance Sensor" type Fuel and Oil
Quantity Indicating Systems. "Non-Capacitance" systems may employ any
measurement technique
current in the art including, but not restricted to, float,
ultra-sonic and fiber optic devices.
The definition of the individual components contained herein is related to the specified Total Installed System accuracy of the entire Fuel or Oil Quantity Indicating System which is a part of the airframe manufacturer's type certification approval data. This data shall be available from the subject airframe manufacturer as published in the operating manual for the aircraft type, model number and configuration. The Fuel or Oil Quantity Indicating System may incorporate optimum compensation based upon measurement of dielectric constant, temperature or density to correct for variations in fuel or oil characteristics due to temperature grade variations or additives. Examples of the type of components covered by this AS are as follows:
Non-compensated capacitance sensor Tank Units.
Self compensating capacitance sensor Tank Units.
Capacitance sensor Compensator Units.
Non-Capacitance type sensors.
Fuel or Oil Quantity Indicators receiving input signals from a capacitance sensor.
Fuel or Oil Quantity Indicators receiving input signals from a non-capacitance type sensor.
Fuel or Oil Quantity Indicators receiving input signals from a Signal Conditioning Unit.
Signal Conditioning Units receiving input signals from a capacitance sensor and delivering output signals to an Indicator.
Signal Conditioning Units receiving input signals from a non-capacitance type sensor and delivering output signals to an Indicator.
Fuel or Oil Quantity indicators receiving input signals from other Fuel or Oil Quantity Indicators. (Totalizer or Repeater Indicators)
Direct density measuring devices.
