What Accuracy in Fuel Level Means for General Aviation

Why would I want accurate fuel gauges in my aircraft. 

Predicting and shaping the future are the providence of engineers.  

If accurate and reliable fuel level sensing for aircraft became a common reality 

What are the effects on the aircraft/pilot interface.

Warnings and Annunciation 

With cross checkable and reliable information between the Fuel Totalizer and Fuel Quantity 

• Low Fuel  
• It is already exists - 
• What if it was reliable and predictable

• Fuel Imbalance - 
• Let you know when you exceeded tank imbalance limits
• Warns you of a rapidly depleting tank - safety  

• Fuel Leakage or Venting  
• Matched information fuel totalizer and tank volume
• If rate of flow d not match - a leakage or venting warning 
• With a residual power or memory input
• Internal leaks annunciated 
• Fuel Theft 

• Errors - 
• As a reliable cross check between fuel flow and fuel tank volume 
• Provides a reliable diagnostic to errors or faulty components in each system
• Failure to follow a predictable path can be flagged as an sensor or tank system requiring maintenance. 

• Secondary Fuel Totalizer - Cross check to the fuel we can derive rate to give a simple totalizer function.

Automation 

With cross checkable and reliable information - Fuel Totalizer and Fuel Quantity we can use this information to relieve pilot workload 

Fuel  Management Computer - 

• Tank Switching -
• The aircraft system would handle switching between tanks for single engine aircraft.
• This could be overridden manually in the cockpit.

• Fuel Management. 

Allow a pilot to mange total fuel volume on the aircraft with an interconnected pump system 

• Minimizes human refueling errors 
• Cross-check quantity of fuel added and correct
• Manage the fuel added or remaining to balance tank volumes.
• Use fuselage wing tanks for weight and balance corrections or trim
