Weather Briefing

MVFR

Islamabad International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 10,000 feet and 6 km visibility.

Wind Analysis

Winds are from the southeast (130°) at 4 knots.

Visibility & Ceiling

Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 10000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 33°C (91°F) with a dewpoint of 13°C, indicating very dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

Forecast Outlook

The TAF forecast covers the next 30 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Haze, Light Thunderstorm Rain, Smoke. There is a 30% probability of IFR conditions with Light Thunderstorm Rain between 08:00Z and 12:00Z. Temporary MVFR conditions are forecast with Smoke between 17:00Z and 21:00Z. Temporary IFR conditions are forecast with Smoke between 21:00Z and 04:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.

About Islamabad International Airport

Overview

Islamabad International Airport serves as a key aviation hub located in Attock, Pakistan. Situated at an elevation of 1761 ft mean sea level, the airport provides critical connectivity for the region with its substantial infrastructure. The airport features two parallel runways, each 12,001 feet long and constructed with asphalt surfaces.

Flying Conditions

The airport's elevation of 1761 ft suggests a moderate altitude environment with potential for temperature and density altitude variations. Pilots should anticipate standard atmospheric conditions typical of the region, which may include seasonal temperature fluctuations that could impact aircraft performance. The parallel runway configuration provides operational flexibility across different wind conditions.

Notable Features

Located at coordinates 33.549000, 72.825660, Islamabad International Airport is positioned in a geographical context that may involve complex terrain interactions. The dual parallel runways (10L/28R and 10R/28L) offer strategic operational advantages, enabling simultaneous approaches and increased airport capacity. The consistent 12,001-foot runway lengths support operations for a wide range of aircraft types.

Approach Considerations

Runway orientation at 10/28 indicates potential prevailing wind alignments from east-southeast to west-northwest. The identical runway lengths of 12,001 feet provide equivalent operational capabilities for approaches from either direction. Pilots should conduct standard terrain and wind assessments when planning arrivals or departures at this facility.
