Abstract: A ground-based system and method of supplying electrical power and temperature-controlled air to an aircraft environmental control system during ground support operations uses a throttle valve to control the flow of compressed air flowing through a heat exchanger. An air conditioner module mounted on a wheeled cart removes heat from the compressed air that is supplied to it from an auxiliary power unit (APU), and supplies cooled compressed air at a desired temperature. The temperature of the cooled compressed air is controlled by selectively positioning a throttle valve, which regulates compressed air flow from the compressed air source. The throttle valve position is controlled in response to one or more ambient meteorological conditions and/or the amount of electrical power being supplied from the system.

Abstract: An ice harvesting prevention mechanism, including an actuator, is provided for an ice maker. The ice maker is arranged to make, harvest and dispense ice to an ice bucket located in an ice receiving position. An ice harvesting prevention device is arranged to prevent dispensing of ice in a first position of the actuator and to permit dispensing of ice in a second position of the actuator. The ice bucket itself, or a movable button carried on the ice bucket, may engage the actuator, when the ice bucket is placed in the ice receiving position, to move the actuator from the first position to the second position. The button may be moved to an “off” position to prevent engagement with the actuator, thereby preventing dispensing of ice when the ice bucket is in the ice receiving position.
