Taxi and slope landing symbology for a helicopter
First Claim
1. Taxi and slope landing symbology for a helicopter having a main rotor drive shaft and a main rotor hub defining a hub moment, the main rotor drive shaft and the main rotor hub having hub moment limits, the taxi and slope landing symbology comprising:
- (a) a first symbol for providing a symbolic representation of the hub moment limits;
(b) a second symbol for providing a dynamic symbolic representation of the instantaneous hub moment, and disposed in combination with said first symbol to provide a visual cue of the instantaneous hub moment relative to the hub moment limits; and
(c) a third symbol for providing a symbolic representation of zero hub moment, and disposed in combination with said first symbol and said second symbol to provide a visual cue of the instantaneous hub moment relative to the hub moment limits and said zero hub moment.

Abstract
Taxi and slope landing symbology for a helicopter having a main rotor drive shaft and a main rotor hub defining a hub moment, wherein the main rotor drive shaft and the main rotor hub have hub moment limits. The taxi and slope landing symbology comprises a first symbol for providing a symbolic representation of the hub moment limits, and a second symbol for providing a dynamic symbolic representation of the hub moment, wherein the second symbol is disposed in combination with the first symbol to provide a visual cue of the hub moment relative to the hub moment limits.

8. Taxi and slope landing symbology for a helicopter having a video display subsystem, a main rotor drive shaft and a main rotor hub defining a hub moment, a hub moment sensor subsystem disposed in combination with the main rotor drive shaft for generating data representative of the instantaneous hub moment, a computer subsystem for processing the data representative of the instantaneous hub moment, the computer subsystem being programmed with hub moment limit data representative of hub moment limits for the helicopter, the computer subsystem also including a symbol generator for generating the taxi slope landing symbology in combination with the video display subsystem, the taxi and slope landing symbology comprising:
-
(a) a first symbol for providing a symbolic representation of the hub moment limits; (b) a second symbol for providing a dynamic symbolic representation of the instantaneous hub moment, and disposed in combination with said first symbol to provide a visual cue of the instantaneous hub moment relative to the hub moment limits;
a(c) a third symbol for providing a symbolic representation of zero hub moment, and disposed in combination with said first symbol and said second symbol to provide a visual cue of the instantaneous hub moment relative to the hub moment limits and said zero hub moment. - View Dependent Claims (9, 10, 11, 12, 13, 14)
