This exercise is designed to train aircrew under realistic scenarios that support full spectrum operations against modern threats and replicate today’s contingency operations. This type of training is limited to 10 days each year, with each exercise lasting no more than three days. These events will only occur once each three-month period, as separated into January through March, April through June, July through September, and October through December.

The new PRTC officially opened Sept. 17, 2015 upon its charting by the FAA, and military flying operations began Sept. 18, 2015. This will be the fifth LFE for the PRTC and this news release serves as the official public notification of the event.

The NOTAMs for the exercise, issued by the FAA 72 hours prior to its start, will act as the final official notice.
