Mr. Stephen M. Dickson Senior Vice President Flight Operations

Delta Air L ines, Inc.

1030 Delta Bou levard, Department 207

Atlanta , GA 30320

Dear Mr. Dickson :

This letter is to inform you that we have g ranted y our petition to extend Exemption No.

10818 , as amended

. It transmits our decision, explains its basis, and gives you the conditions

and limitat ions of the exemption, including the date it ends.

The Basis for Our Decision

By letter dated August 27, 2015 , you petitioned the Federal Aviation Administration (FAA)

on behalf of Delt a Air L ines

, Inc. (Delta) for an extension to Exemption No. 10818 , as amended . That exemption from § 91.9(a ) of Title 14, Code of Federal Regulations (14 CFR)

allow s a select group of Delta Senior Line Check Airmen Pilots to operate the Apple iP ad or

Microsoft Surface Tablet

, WiFi

- only as approved device s on the flight dec k under certain conditions and limitations for the purpose of conducting research into turb ulence mitigation

and avoidance

.

In your petition, you indicate that there has been no change in the conditions and reasons relative to public interest and safety t hat were the basis for granting the original exemption.

The FAA has determined that good cause exists for not publishing a summary of the petition

in the Federal Register because the requested extension of and amendment to the exemption

would not set a precedent, and any delay in acting on this petition would be det rimental to

Delta
