Abstract

A dual switch arm and mode select system for monitoring an ejection mode selection of an ejection system may include a controller. An ejection mode selector, a first arm switch assembly, a second arm switch assembly, and a display may be in communication with the controller. The controller may determine an ejection mode of the ejection system based on a signal received from the ejection mode selector. The controller may determine a position of the first arm switch assembly and a position of the second arm switch assembly. The controller may command the display to output at least one of a fault-free signal, a fault signal, or a warning signal based on the ejection mode and the positions of the first arm switch assembly and the second arm switch assembly.

Dependent claims

A dual switch arm and mode select system for monitoring an ejection mode selection of an ejection system, the dual switch arm and mode select system comprising:

a controller;
an ejection mode selector in communication with the controller;
a first arm switch assembly in communication with the controller, the first arm switch assembly being configured to translate between a safe position and an armed position;
a second arm switch assembly in communication with the controller, the second arm switch assembly being configured to translate between the safe position and the armed position;
a display in communication with the controller;
and
a tangible, non-transitory medium configured to communicate with the controller, the tangible, non-transitory medium having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising:
determining, by the controller, an ejection mode of the ejection system based on a signal received from the ejection mode selector;
determining, by the controller, a position of the first arm switch assembly;
determining, by the controller, a position of the second arm switch assembly;
and
commanding, by the controller, the display to output at least one of a fault-free signal, a fault signal, or a warning signal based on the ejection mode, the position of the first arm switch assembly, and the position of the second arm switch assembly.

An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon for monitoring an ejection mode selection of an ejection system and that, in response to execution by a controller, cause the controller to perform operations comprising:

determining, by the controller, an ejection mode of the ejection system;
determining, by the controller, a position of a first arm switch assembly of a first ejection seat;
determining, by the controller, a position of a second arm switch assembly of a second ejection seat;
and
commanding, by the controller, a display to output at least one of a fault-free signal, a fault signal, or a warning signal based on the ejection mode, the position of the first arm switch assembly, and the position of the second arm switch assembly.

2 more elements

A method for monitoring an ejection mode selection for an ejection system, the method comprising:

determining, by a controller, an ejection mode of the ejection system;
determining, by the controller, a position of a first arm switch assembly of a first ejection seat, the position of the first arm switch assembly being at least one of an armed position or a safe position;
determining, by the controller, a position of a second arm switch assembly of a second ejection seat, the position of the second arm switch assembly being at least one of the armed position or the safe position;
and
commanding, by the controller, a display to output at least one of a fault-free signal, a fault signal, or a warning signal based on the ejection mode, the position of the first arm switch assembly, and the position of the second arm switch assembly.
