I was just looking at the photo of ATA's beautiful "new" DC-10 and I noticed something...Take a look first at her in Northwest Airlines colours and then again in ATA's colours:

In front of the nose landing gear doors, I see the standard air intake devices; however, on the ATA bird, I now see an additional intake device that was not present before. What is this device? Is it unique to ATA?
