All of Washington Dulles International Airport — runways, frequencies, charts and live weatherBefore taxi Dulles
- ATIS 134.85
- A recorded loop of the field's weather, active runway and any notices, updated hourly or whenever conditions change. Listen before your first call, and tell the controller which letter you have so they do not read it to you again.
- ASOS/AWOS 134.85
- An automated weather station reading the field conditions aloud — wind, visibility, ceiling, temperature and altimeter. It replaces ATIS at a field with no controller to record one. Get the altimeter setting before you descend below the transition altitude.
- Clearance 135.7
- Clearance delivery issues your IFR clearance, and at busier fields your VFR departure instructions and squawk code. Call before you request taxi, with the ATIS letter and your intended direction of flight.
