For clearance delivery when the airport traffic control tower is closed, contact Philadelphia Approach.
Taxiway E is closed to aircraft with a wingspan greater than 110 feet, except with 24-hour prior permission.
Noise abatement procedures are in effect. Departures over 12,500 pounds must fly runway heading until reaching 1,700 feet MSL, and departures under 12,500 pounds must fly runway heading until reaching 1,200 feet MSL.
Taxiway C is closed to aircraft weighing more than 40,000 pounds.

Frequently asked questions
Does KTTN have customs and immigration services on site?
Trenton Mercer Airport has CBP inspection services available on site along with a USDA compliance agreement covering agricultural clearance. This means arriving international flights can be processed for customs directly at KTTN rather than being routed to a nearby port of entry. The airport does not list a nearest alternate customs airport, consistent with its own on-site capability. Dispatchers planning international arrivals should confirm current CBP staffing and any prior notice requirements before filing, since availability details beyond the compliance agreement are handled through direct coordination with the inspection service.
What runways are available at Trenton Mercer, and what is the longest one?
Trenton Mercer Airport operates two paved runways: 06/24 at 6,006 feet and 16/34 at 4,800 feet, both 150 feet wide with asphalt surfaces. Runway 06/24 is the longer of the pair and matches the airport's published maximum paved runway length. Both runways carry engineered material arresting systems at their departure ends, a detail relevant to overrun planning. High-intensity runway lights on both runways, along with MALSR on runway 06 and PAPI and REIL on the remaining runway ends, can be pilot-activated on CTAF when the tower is closed.
Are there noise abatement procedures or curfews in effect at KTTN?
Trenton Mercer Airport enforces noise abatement departure procedures tied to aircraft weight. Aircraft departing at more than 12,500 pounds are required to fly runway heading until reaching 1,700 feet MSL, while aircraft under that weight fly runway heading until 1,200 feet MSL. The airport also maintains a voluntary curfew from 0000 to 0600 local time. Separately, touch-and-go and training operations are prohibited between 2200 and 0700. Dispatchers scheduling late-night or early-morning movements at KTTN should account for both the curfew and the training restriction when planning arrivals and departures.
What taxiway restrictions apply to larger aircraft at Trenton Mercer?
Trenton Mercer Airport restricts two taxiways based on aircraft size. Taxiway E is closed to aircraft with a wingspan greater than 110 feet, except with prior permission granted 24 hours in advance. Taxiway C is closed to aircraft weighing more than 40,000 pounds. Operators of larger business jets or any aircraft approaching these thresholds should verify routing with airport operations before filing a flight plan into KTTN, since these restrictions affect taxi planning between runways and ramp areas rather than runway use itself.
What wildlife hazards and coordination procedures should crews know about at KTTN?
Trenton Mercer Airport reports geese, flocks of sea gulls, and deer both on and in the vicinity of the airport, a standing wildlife hazard for arriving and departing traffic. Separately, tower controllers have an obstructed view of taxiway J, a factor requiring caution during ground movements in that area. When the tower is closed, clearance delivery functions are handled by contacting Philadelphia Approach. ARFF also monitors both ground and tower frequencies during ATC zero events, ensuring emergency response coordination continues even without normal tower staffing at Trenton Mercer.
