Abstract:
A tip alarm system for an aircraft having a nose landing gear (NLG) includes a sensor having first and second parts respectively disposed on first and second portions of the NLG that are respectively fixed to the aircraft and moveable relative to the fixed portion and operable to detect the position of the first and second portions relative to each other and to produce a tip alarm signal when the first and second NLG portions are disposed at a selected position relative to each other corresponding to an imminent aircraft tipping condition and thereby prevent the aircraft from tipping back onto the ground due to improper loading of the aircraft.
