About Portland International Jetport

Overview

Portland International Jetport serves as a critical aviation hub in southern Maine, located in the city of Portland. The airport supports both commercial passenger and general aviation operations, situated at an elevation of 76 feet mean sea level. Its strategic coastal location provides essential transportation infrastructure for the greater Portland metropolitan area.

Flying Conditions

The airport experiences typical New England maritime weather patterns with significant seasonal variations. Winter months can present challenging conditions with potential snow and low visibility, while summer periods generally offer more stable flying conditions. Pilots should anticipate potential wind shifts and maritime-influenced meteorological dynamics given the airport's proximity to the Atlantic coast.

Notable Features

Portland International Jetport features two paved runways: Runway 11/29 at 7,200 feet and Runway 18/36 at 5,001 feet. The dual runway configuration provides operational flexibility for different wind conditions and aircraft types. Its location near the coast suggests potential for rapidly changing wind conditions that pilots must carefully monitor during approach and departure.

Approach Considerations

Runway selection will primarily depend on prevailing wind direction, with the longer 7,200-foot Runway 11/29 offering more landing options for larger aircraft. The airport's coastal positioning means wind can significantly influence approach strategies, particularly during transitional seasonal periods. Pilots should review current meteorological data and be prepared for potential crosswind landing requirements.
