Within limits?

The Current Tab gives a quick indication of the current conditions needed to make a Go/No Go decision. The color coded backgrounds let you see right away whether the conditions are within your personal limits.

The data on this page is standard METAR data from NOAA’s National Weather Service Aviation Digital Data Service.

The data initially shown on this Tab is for the Default Station defined on the Options Tab. Weather from any METAR station can be displayed by keying it’s Station Identifier.

Field Descriptions

Area A

4-letter ICAO Station Identifier - This is the standard station identifier. Enter a valid station id here to display the METAR data for that station.

Station Name - This station name

User Optional Links 1, 2 and 3 - These 3 links are defined by the user and are discussed in more detail under the Options Tab. The above example shows links that may be used to open up a web browser to a related web site—in the example the AirNav, AOPA or charts web sites.

Station City, State, Country - This station city, state and country

Area B

AFC Aviation Flight Category - As defined in the NOAA Aviation Weather Center. The background color for this field will change from green to yellow if the category is below VFR.

Area C

Runways - This area shows the runway dimensions, headwind and crosswind. The headwind and crosswind will have a green, yellow or red background depending on the user limits defined on the Options Tab. The Takeoff and Landing distances are calculated using performance data for the Airplane shown in the box below.

Area D

Day and Time - This area shows the day and time for the currently displayed METAR. This is shown in both UTC and Local time.

Area E

Elevation - Station elevation MSL

Pressure Alt - Calculated pressure altitude

Density Alt - Calculated density altitude

Altimeter - METAR altimeter setting

Area F

Graphic Wind Direction and Speed - METAR wind direction and speed

Area G

*Visibility - METAR visibility

*Ceiling - METAR ceiling

*Temp. C/F - METAR temperature Celsius and calculated Fahrenheit

Dew Pt C/F - METAR dew point Celsius and calculated Fahrenheit

Wind Direction - METAR wind direction

*Speed - METAR wind speed

*Gust - METAR wind gust

Area H

Sky Condition - METAR sky condition

Present Weather - METAR present weather NOTE: If an alternate METAR station is being used for the displayed station it will be highlighted here. See the Airport Tab for more information about alternate METAR stations.

Area I

Winds Aloft Forecast - The Winds Aloft Forecast is shown in this box. The URL used to retrieve this forecast is defined on the Options Tab. By default it shows the 6-hour forecast for forecast stations within 150 miles. This can be changes on the Options Tab to show the forecast for All stations or for a different distance.

Area J

Refresh Button - Click this button to update the display with the latest METAR data.

Area K

METAR selection slider - Up to 36 hours of METAR data will be displayed for the selected station. This slider may be used to slide through this data. Ad the slider is mover from right to left the displayed data will move back in time.

Area L

Station Quick Select Buttons - These buttons may be used to quickly display data for the stations defined on the Options Tab as Button Airports.

Area M

Wind Direction - Up to 36 hours of wind direction data is displayed

Wind Speed - Up to 36 hours of wind speed data is displayed. The blue dot shows the wind speed, if there is a gust speed in the METAR it is displayed as a red dot.

Area N

Visibility - Up to 36 hours of visibility is displayed. Any value over 10 miles is displayed as 10 miles

Ceiling - Up to 36 hours of ceiling (OVC or BKN) data is displayed as a blue dot. The lowest layer below this ceiling may be displayed as a red dot. The highest ceiling level displayed is 20,000.

Area O

Altimeter - Up to 36 hours of the altimeter setting is displayed

Temperature/Dew Point - Up to 36 hours of temperature and dew point data is displayed. The temperature is shown as a blue dot, the dew point as a red dot.

Area P

Runway Panel (s) - Up to 4 runway panels will be displayed depending on the runway configuration for the airport. The runway is drawn with a north orientation, and the runway is positioned based on the runway identifier, this is not drawn to scale. The numbers at the end of the runway indicate the preferred runway based on the wind direction. The red (hot) numbers indicate the preferred runway, the blue numbers indicate the reciprocal runway.

In the lower left of this panel are two sliding scales that indicate the relative strength of the headwind and crosswind components for this runway. The colors of these scales (green, yellow and red) are controlled by the personal limits set on the Options Tab.

There is an orange arrow that shows the wind direction.

Each panel shows:

Runway Identifier - The runway identifier shown in a mandatory instruction sign. The runway heading is selected based on the wind direction. For example if we have runway 36/18 and a northerly wind we will select runway 36, if we have a southerly wind we will select runway 18.

H Wind - The calculated headwind for this runway

X Wind - The calculated crosswind for this runway, if there is a value for wind gust the crosswind component is calculated and shown below the regular crosswind value

Area Q

The METAR - This is the METAR that contains the raw data displayed on this TAB

METARs - Click on this link to see the raw METAR data used to plot the charts.

Status Line - This line displays the current date and time on the right and a status message on the left.

Area R

Station Distance and Bearing - Enter a station identifier here to calculate the distance and bearing from the current station to the station entered. In order for the calculation to be performed the Longitude and Latitude in Seconds must be correctly entered in the Airport database. By default the database contains this data for most US airports.

* - For these fields, the background color changes based on settings defined on the Options Tab.
