Abstract
There are described systems and methods for annunciating engine lubricating fluid level. The system comprises a first fluid level sensor for a first engine; a first low-level detector coupled to the first fluid level sensor; a first low-level indicator coupled to the first low-level detector for annunciating a fluid level of the first engine below a minimum operating level; and an annunciation and display system coupled to the first low-level detector and configured for performing non-critical lubricant-related functions. The first fluid level sensor, the first low-level detector, and the first low-level indicator are composed of first components having a critical level of reliability, the annunciation and display system is composed of second components having a non-critical level of reliability.
