Replacement Terminal Environmental Assessment

13. The 2018 Actual Operations Numbers at TTN Exceeded the 2035 Projections. What Impacts Does This Have On the Replacement Terminal and Airport Master Plan for the Future of Operations at TTN?

The Master Plan went through a process to develop projections for 20 years. The data used for the Master Plan included actual operations data from 2014 and projected the operations through 2035. The projections were based upon local, regional, and national trends and standards for similar airports and markets, and were reviewed and approved by the FAA during the Master Plan process. The projections identified in the Master Plan, Section 2 – Aviation Forecasts, Table 2-10: Annual Operations Forecast include the following categories:

  • Air Carrier/Air Taxi – Airlines, Charter, Corporate

  • Itinerant General Aviation – Activity originating or terminating More Than 50 nautical miles (NM) from TTN

  • Local Civil/General Aviation – General aviation operations originating or terminating Less Than 50 – Local short trips, flight school, “touch and go”

  • Military – National Guard and State Police operations


The Master Plan and associated appendices can be reviewed online at:

When looking at the actual data from 2017, 2018 and the first half of 2019, the changes that have occurred since the 2014 time include increases in the GA Itinerant Operations (those operations originating from or departing to destinations greater than 50 miles) and the GA Local Operations (those operations originating from or departing to destinations within 50 miles). The increase in GA Local Operations is almost entirely due to the operations of flight schools located at TTN.

Overall the combined air carrier and air taxi operations are down with a very small increase in operations from 2018 through 2019. The lower number of flights is offset by the increase in enplanements at TTN since data was collected in 2014. This is primarily due to changes in aircraft being used at TTN which have changed from a fleet of A319 aircraft in 2014 and 2015 to A320 aircraft which are capable of carrying more passengers. This is coupled with nearly full flights that are currently seen daily at TTN.
