Abstract

A communications system for an aircraft carrying personnel having personal electronic devices (PEDs) includes a wireless access device in the aircraft for the PEDs, and an aircraft server in the aircraft cooperating with the wireless access device for determining airborne validation of a ground server address entered via a corresponding PED. An air-to-ground transceiver in the aircraft cooperates with the aircraft server for communicating over an air-to-ground interface the airborne validated ground server address. A ground server on the ground receives the airborne validated ground server address over the air-to-ground interface, determines ground validation of the airborne validated ground server address, and provides ground access for the corresponding PED for which the entered ground server address has both airborne and ground validation.

6. The communications system according to claim 5 wherein the ground server address corresponds to a uniform resource locator (URL).

7. The communications system according to claim 1 wherein said aircraft server determines airborne validation of the at least one entered ground server address by comparing to an airborne whitelist of accepted ground server addresses.

8. The communications system according to claim 1 wherein said aircraft server determines airborne validation of the at least one entered ground server address by comparing to an airborne blacklist of rejected ground server addresses.

9. The communications system according to claim 1 wherein the at least one entered ground server address corresponds to a uniform resource locator (URL);

and wherein said aircraft server determines airborne validation by determining if the URL has a valid URL syntax.

10. The communications system according to claim 1 wherein said aircraft server returns an error message to the PED when a ground server address associated therewith fails airborne validation.

11. The communications system according to claim 1 wherein said ground server determines ground validation of the at least one airborne validated ground server address by comparing to a ground whitelist of accepted ground server addresses.

12. The communications system according to claim 1 wherein said ground server determines ground validation of the at least one airborne validated ground server address by comparing to a ground blacklist of rejected ground server addresses.

13. The communications system according to claim 1 wherein the at least one airborne validated ground server address corresponds to a uniform resource locator (URL);

and wherein said ground server determines ground validation by determining if the URL has a valid URL syntax.

14. The communications system according to claim 1 wherein said ground server returns an error message over the air-to-ground interface to the PED when an airborne validated ground server address associated therewith fails ground validation.

15. The communications system according to claim 1 wherein said aircraft server maintains an airborne whitelist of accepted ground server addresses;

and wherein said ground server dynamically updates the airborne whitelist over the air-to-ground interface.

16. The communications system according to claim 15 wherein the dynamic updates to the airborne whitelist are temporary.

17. The communications system according to claim 15 wherein the dynamic updates to the airborne whitelist expire at an end of a flight of the aircraft.

18. The communications system according to claim 1 wherein the at least one ground server address corresponds to at least one email server address;

and wherein said at least one ground server interfaces with an email server.

19. A communications system for an aircraft carrying at least one person having a personal electronic device (PED) for exchanging emails outside the aircraft, the communications system comprising:

at least one access point in the aircraft for providing a wireless local area network (WLAN) for the PED, with the PED accessing a web-based email prompt via the WLAN;

an aircraft server in the aircraft cooperating with said at least one access point for determining airborne validation of at least one email server address entered by a corresponding PED via the web-based email prompt;

an air-to-ground transceiver in the aircraft cooperating with said aircraft server for communicating over an air-to-ground interface the at least one airborne validated email server address; and

at least one email server having a firewall associated therewith on the ground for receiving the at least one airborne validated email server address over the air-to-ground interface, determining ground validation of the at least one airborne validated email server address, and providing email access for the corresponding PED for which the entered at least one email server address has both airborne and ground validation.

20. The communications system according to claim 19 wherein said aircraft server determines airborne validation of the at least one entered email server address by performing at least one of the following:

comparing the at least one entered email server address to an airborne whitelist of accepted email server addresses; and
