About El Centro NAF Airport (Vraciu Field)

Overview

El Centro NAF Airport (Vraciu Field) is a medium-sized naval air facility located in El Centro, California, situated at an unusually low elevation of -42 feet mean sea level. The airport serves naval aviation operations with two substantial runways capable of handling significant aircraft traffic. Its geographic position in Southern California provides strategic operational capabilities for military and potentially some civilian aviation activities.

Flying Conditions

The airport experiences predominantly excellent visual flight conditions, with 97% of observations reporting VFR weather. Temperature ranges from 2°C to 41°C, with an average of 19.2°C, indicating significant thermal variability. Wind patterns are consistent from the west (270°), averaging 6.3 knots with occasional stronger gusts up to 30 knots, though calm conditions occur 18.4% of the time. September, October, and December represent the most favorable VFR months for aviation operations.

Notable Features

Both runways (08/26 and 12/30) are constructed with PEM (Possibly Equivalent Material) surfaces and offer substantial lengths of 9,503 and 6,823 feet respectively. The airport's negative mean sea level elevation is a unique geographical characteristic that could influence atmospheric and aircraft performance conditions. Both runways demonstrate excellent wind alignment, with 100% favorable wind coverage and minimal average crosswind components of 2.8 and 3.7 knots.

Approach Considerations

Pilots can expect consistently favorable wind conditions for both runways, with minimal crosswind challenges. Average visibility of 9.8 statute miles and extremely low occurrence of reduced visibility (only 0.6% below 3SM and 0.5% fog) suggest generally excellent approach conditions. The substantial runway lengths provide ample landing and takeoff capabilities for most aircraft types, with Runway 08/26 offering the longest surface at 9,503 feet.
