Abstract: An oil level measurement system for an aircraft engine includes a magnetic float disposed in the aircraft engine, a first sensor ladder configured for sensing a position of the magnetic float, and a second sensor ladder configured for sensing a position of the magnetic float. A controller is configured to determine an oil level of an engine based on an engine status signal, a first signal from the first sensor ladder, and a second signal from the second sensor ladder. An oil level sensing method for measuring an oil level within an aircraft engine when the aircraft engine is off includes comparing a first signal from a first sensor ladder with a second signal from a second sensor ladder, indicating a fault when the first signal is different from the second signal, and determining an oil level of an aircraft engine when the first signal matches the second signal.
