Weather Briefing

VFR

Grabtsevo Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 500 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north-northeast (20°) at 2 knots.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: scattered at 500 ft.

Temperature & Moisture

Temperature is 20°C (68°F) with a dewpoint of 19°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 9 hours. Conditions are expected to remain MVFR throughout the forecast period.

Pilot Recommendations

Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

As a medium-sized airport, it provides critical aviation infrastructure for central Russia, supporting regional transportation and potentially military or commercial operations.

Flying Conditions

Weather conditions at Grabtsevo demonstrate significant variability, with instrument flight rules (IFR) dominating approximately 50.6% of observations. Pilots should anticipate challenging conditions, with low-level IFR (LIFR) occurring in 25.7% of reports and marginal VFR (MVFR) in 21.3% of cases. Temperature ranges extensively from -25°C to 27°C, suggesting preparation for extreme seasonal variations.

Notable Features

The airport features a single asphalt runway (13/31) measuring 6,885 feet in length, suitable for medium-sized aircraft operations. Its location in the Kaluga region suggests potential terrain complexity, with elevation at 656 feet indicating a relatively moderate terrain profile typical of central Russian landscape.

Approach Considerations

September, October, and January represent the most favorable VFR months for operations at Grabtsevo. Pilots should expect occasional fog (7% of observations) and prepare for potential reduced visibility scenarios. The runway orientation (13/31) suggests wind considerations during approach and landing procedures.
