The course is derived from the runway designator (number × 10), not from a survey - the actual magnetic bearing can differ by a few degrees.

Declared distances (TORA, TODA, ASDA, LDA) are published in the national AIP - they are not part of this table.

Climate at Blake Field (Delta) - statistics from METAR reports

What the METAR reports from KAJZ for 2023-2025 show - counted hour by hour.

IFR and LIFR conditions are rare here at any time of day.

Fog (FG) was reported on 1.6 days a year on average, most often in March. Thunderstorms (TS) occurred on 17 days a year on average, and snowfall on 25.

The wind most often blows from NE (45°) - 10% of reports. Calm (0 kt) made up 28% of reports, and gusts of 25 kt or more appeared in 2%. Warmest month: July (average high 37.1 °C); coldest: January (average low -5.0 °C).

Source: routine METAR reports from the Iowa Environmental Mesonet archive (Iowa State University), 2023-2025. Flight categories use the FAA thresholds, widely used as a convention. A day counts when it has at least 12 reports. These are statistics of past conditions - not a forecast or a substitute for a pre-flight briefing.

Runways at KAJZ

According to OurAirports data (compiled from AIP and FAA sources), Blake Field (Delta) has one runway: 03/21 - 1,706 m long (5,598 ft), 23 m wide, asphalt surface.

Runway headings and wind

The thresholds are oriented as follows: 03/21 on 30° and 210° magnetic. A threshold designator is its magnetic heading divided by ten (ICAO Annex 14), so the runway axis can be read straight off the numbers.

For the 03/21 axis, wind from the south-east (around 120°) or from the north-west (around 300°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 30° or 210° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.

METAR and TAF for KAJZ

Weather reports for Blake Field (Delta) are published under the ICAO code KAJZ. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.

The decoder breaks the KAJZ report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.

Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for KAJZ, check the nearby airports listed below.

Reports always use UTC (the Z suffix). The America/Denver zone is GMT-07:00 in winter and GMT-06:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.

The closest airports in the database, measured in a straight line from the reference point, are Montrose Regional Airport (KMTJ, 34 km), Grand Junction Regional Airport (KGJT, 55 km), Hopkins Field (Nucla) (KAIB, 75 km). When no report is available for KAJZ, they usually give the best approximation of conditions in the area.
