Runway cards
The reported wind is at the top, then one card for each runway with both of its ends. The end that points more to the north is listed first, for example 01L then 19R. Helipads aren’t listed.
Reading a card
- Runway heading — the runway number, then its magnetic heading in parentheses. An asterisk (*) means the magnetic heading isn’t available.
- A runway drawing with an arrow for the wind: green for a headwind, red for a tailwind.
- Green arrow — headwind component in knots. A red arrow means a tailwind.
- Blue arrow — crosswind component in knots, pointing to show which side it comes from.
- RVR on the left: touchdown (TD), midpoint (M), and rollout (RO), where reported. Red below 1,800 ft, orange below 2,400 ft, green above.
How the components are calculated
- Gusts: when gusts are reported, the components use the gust speed.
- Reference: METAR and TAF winds are true. ATIS, ASOS/AWOS broadcasts, tower winds, and runway numbers are magnetic.
- Not shown: when the wind is calm or variable, or when no heading is on file for that runway.
Check the numbers. Runway data comes from public airport databases and can be out of date. Compare with the current ATIS, your charts, and your aircraft’s limits.
Crosswind Calculator from a runway
- Tap a runway card. The Crosswind Calculator opens with that runway and the current wind filled in.
- Adjust the runway heading, wind direction, and wind speed to try other conditions.
The crosswind it shows matches the runway card.
The drawing shows the real runway designator (for example 16L) until you move the runway heading dial.
