When tensions in contested regions rise, the FAA tends to restrict civilian air traffic around those areas, forcing them to fly less-direct routes that cost more in time and fuel burn.

The Air Line Pilots Association, a union that represents FedEx pilots along with those at other carriers, did not immediately return a request for comment on the measure. FedEx did not immediately return a request for comment.

Background: FedEx applied to acquire the capability in 2019; Friday’s notice lays out the proposed technology and seeks comments about it. Because the system is beyond the design scope of FAA certification, it requires a special condition approval, the notice said. The infrared system must meet the FAAs airworthiness standards.


Its not uncommon for aircraft flying sensitive routes to have additional defense measures. El Al Israel Airlines, for example, has anti-aircraft missile technology aboard its commercial aircraft. The VC-25 aircraft, commonly known as Air Force One when the president is on board, have both electronic and infrared countermeasures to jam or divert incoming missiles.

There have been incidents of surface-to-air missiles striking both cargo and commercial jets transiting through hostile areas over the years. In 2003, an Airbus DHL Express cargo plane took a hit to its left wing from a shoulder-fired missile, crippling its hydraulic system shortly after takeoff from Baghdad in Iraq. The three-man crew were not injured in the incident.

More recently, Ukraine International Airlines Flight 752 was shot down by more sophisticated military-grade surface-to-air missiles upon taking off from Tehran, Iran, in 2020, killing all on board.

The technology was previously tested in some cargo jets in 2008.

Whats next: The novel or unusual design feature can only apply to its A321 model, the FAA said, unless the company applies for supplemental certification to upgrade other models. The proposed special condition will be published in the Federal Register on Jan. 18, with comments open for 45 days after that.
