About New Orleans NAS JRB/Alvin Callender Field

New Orleans NAS JRB/Alvin Callender Field is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the US AIP for current access procedures and restrictions.

Overview

New Orleans NAS JRB/Alvin Callender Field serves as a joint reserve base located in the greater New Orleans area. Situated at a low elevation of 2 feet MSL, the airport supports military and potential civil aviation operations with two substantial asphalt runways. Its strategic location in southeastern Louisiana provides critical infrastructure for regional aviation activities.

Flying Conditions

Weather conditions at KNBG demonstrate predominantly favorable flying conditions, with 75.2% of observations reporting VFR status. Seasonal temperature ranges from -3°C to 33°C suggest potential winter and summer operational considerations. Wind patterns are predominantly northerly at an average of 7.1 knots, with calm conditions occurring 24.4% of the time, indicating generally stable atmospheric conditions.

Notable Features

The airport features two parallel runways: Runway 04/22 at 9,999 feet and Runway 14/32 at 6,000 feet, both constructed with asphalt surfaces. Both runways demonstrate 100% wind compatibility, with minimal average crosswind velocities (3.9kt and 5kt respectively). The extremely low elevation of 2 feet MSL indicates a flat terrain characteristic typical of the Gulf Coast region.

Approach Considerations

Pilots should anticipate optimal VFR conditions during September, October, and November based on historical meteorological data. Visibility averages 8.9 statute miles, with only 4.2% of observations reporting visibility below 3 miles. Occasional fog (6.7% of observations) and potential low-visibility conditions suggest maintaining standard instrument approach preparedness.
