1. A method, comprising:
calibrating a first sensor to measure a first condition between a first stop pad and a second stop pad of a levered landing gear;
measuring the first condition when the first stop pad is in contact with the second stop pad; and
in response to the first condition satisfying a threshold, generating an alert related to the first condition,
wherein the levered landing gear includes:
a first shock strut that includes the first stop pad; and
a truck lever that includes the second stop pad and is coupled to the first shock strut to pivot relative to the first shock strut between an extended position and a static position relative to the first shock strut, and wherein the first stop pad makes physical contact with the second stop pad when the truck lever is in the static position to form a stop joint for the levered landing gear.
