Can I use ForeFlight Mobile to file a flight plan into the DC FRZ?

While you can use ForeFlight Mobile to file a flight plan to an airport in the DC SFRA (by selecting DC SFRA flight plan type on the Flights page) flights into the FRZ cannot be filed electronically using ForeFlight Mobile, or any other civilian app/online service.

You can contact the Washington Center’s Flight Data Unit at 703-771-3476 to file a flight plan into the DC FRZ.
