Abstract

An expedited preflight readiness system for aircraft includes a power source having one or more battery modules for storing electrical power. An integrated controller is electrically and communicatively coupled with the power source for monitoring and controlling the power source to provide electrical power to aircraft subsystems. A mobile device is communicatively coupled with the integrated controller for communicating instructions to the integrated controller for initiating preflight readiness of the aircraft and for monitoring preflight readiness. A method for preconditioning an aircraft includes determining a state-of-charge of an APU and activating an environmental control subsystem for preconditioning the aircraft by adjusting a current temperature according to a preconditioning profile based on one or more of a target temperature, a target time, the current temperature, an outside air temperature, an amount of energy, and a state-of-charge of the APU.

First claim

We claim:

1. An expedited preflight readiness system for an occupiable aircraft, comprising:
an auxiliary power source having one or more battery modules for storing electrical power, the auxiliary power source being electrically coupled to a plurality of aircraft subsystems on the occupiable aircraft for enabling preflight readiness and powering the plurality of aircraft subsystems when a primary power source is unavailable;
an integrated controller electrically and communicatively coupled with the auxiliary power source for monitoring and controlling the auxiliary power source to provide electrical power to one or more of the plurality of aircraft subsystems; and
a mobile device communicatively coupled with the integrated controller via a server, the mobile device configured to initiate display status information about the plurality of subsystems for monitoring preflight readiness and for communicating instructions to the integrated controller for initiating preflight readiness, wherein the mobile device is configured to receive selections for starting one or more of the plurality of aircraft subsystems prior to arrival of a flight crew at the location of the occupiable aircraft.

2. The system of claim 1 , wherein the mobile device is configured to: (i) remotely initiate aircraft preflight preparations via the integrated controller; (ii) provide remote monitoring of the plurality of aircraft subsystems; and (iii) receive selections for starting one or more of the plurality of aircraft subsystems, all while the aircraft is unattended and without the use of cockpit presets.

3. The system of claim 1 , wherein the auxiliary power source is configured to provide electrical power under control of the integrated controller to an avionics suite of the aircraft enabling remote preflight checks using the mobile device.

4. The system of claim 1 , wherein the mobile device is configured to display temperature readings for an aircraft cockpit via a plurality of interactive temperature indicators, the plurality of interactive temperature indicators each configured to receive a selection for setting a target temperature of the aircraft cockpit.

5. The system of claim 1 , wherein the mobile device is configured to display a voltage value, a current value, a temperature value, and a state-of-charge value for the auxiliary power source.

6. The system of claim 1 , wherein the mobile device is configured to present of a tire pressure indicator for displaying a tire pressure for each of a respective plurality of tires onboard the aircraft.

7. The system of claim 1 , wherein the mobile device is configured to enable selection of a fuel quantity indicator for displaying a quantity of fuel in one or more fuel tanks.

8. The system of claim 1 , wherein the mobile device is configured to present of one of a plurality of security-camera icons, the selection of any of the icons in the plurality of icons activating a respective security camera to display a live camera view of an aircraft component on the mobile device.

9. The system of claim 1 , wherein the mobile device is configured to enable selection one of a plurality of interactive door-lock indicators; the mobile device further configured to allow displaying a locked or unlocked status of a plurality of aircraft doors, the plurality of interactive door-lock indicators further enabling remote locking and unlocking of the plurality of aircraft doors.

10. A method for preconditioning an aircraft, the aircraft having an integrated controller electrically and communicatively coupled with a plurality of aircraft subsystems, the method comprising:
receiving a selection for a target temperature for a crew compartment onboard the aircraft;
receiving a selection for a target time to reach the target temperature;
measuring a current temperature and an outside air temperature;
calculating an amount of energy to reach the target temperature based on the current temperature, the target temperature, the outside air temperature, and the target time;
determining a state-of-charge of an auxiliary-power-unit (APU); and
activating an environmental control subsystem for preconditioning the aircraft by adjusting the current temperature according to a preconditioning profile based on at least two of: (i) the target temperature, iii) the target time, (iii) the current temperature, (iv) the outside air temperature, (v) the amount of energy, and (vi) the state-of-charge of the APU.

11. The method of claim 10 , wherein receiving the selection for the target temperature and the target time is via a mobile device such that activating the environmental control subsystem for preconditioning the crew compartment onboard the aircraft occurs remotely prior to arrival of personnel at the aircraft.

12. The method of claim 11 , further comprising displaying the target temperature and the current temperature via the mobile device for one or more of a cockpit, a cabin, a storage compartment, a seat, and a pilot control interface of the aircraft.

13. The method of claim 11 , further comprising activating electric heaters for remotely activating wing deicing equipment on the aircraft.

14. The method of claim 11 , wherein activating the environmental control subsystem for preconditioning the aircraft comprises:
activating one or more heaters when the current temperature is less than the target temperature; and
activating one or more of vapor-cycle-cooling subsystems (VCCS) when the current temperature is greater than the target temperature.

15. The method of claim 14 , further comprising operating a variable-speed compressor motor of the one or more vapor-cycle-cooling subsystems at a reduced speed to reduce energy use based on the preconditioning profile.

16. The method of claim 15 , further comprising operating the variable-speed compressor motor continuously at a reduced speed to provide a consistent and quieter environmental noise signature by avoiding intermittent high-current discharge surges from the APU.

17. The method of claim 15 , further comprising operating the variable-speed compressor motor at different speeds to facilitate estimation of energy usage and to facilitate determination of a precooling profile based on a constant cooling rate as opposed to a constant compressor speed.

18. An expedited preflight readiness method for an occupiable aircraft, comprising:
sending a signal via a mobile device to a server;
determining whether the signal is a request for data or a command to operate an aircraft environmental control subsystem; and
when the signal is a request for temperature data,
searching aircraft diagnostic data of the server for the temperature data; and
transmitting the temperature data from the server to the mobile device for display; and

when the signal is a command for a target temperature,
transmitting the command to an integrated controller for operating the aircraft environmental control subsystem for preconditioning an aircraft cabin temperature; and
transmitting status of the aircraft cabin temperature to the mobile device for displaying progress towards the target temperature.

19. The method of claim 18 , further comprising authenticating a user of the mobile device.

20. The method of claim 18 , further comprising preprogramming preflight readiness instructions onboard the aircraft prior to shut down, such that the integrated controller automatically operates the environmental control subsystem for preconditioning the aircraft cabin temperature at a prescheduled time without receivi
