Section 2. Customs Notification and ADIZ Requirements

  1. U.S. Customs and Border Protection (CBP) requirements for Advance Passenger Information System (APIS) authorizations are contained in 19 CFR 122 and apply to both inbound and outbound aircraft. Do not include ADCUS in flight plan remarks; pilots are required to coordinate directly with CBP.
  2. Flight plan and customs requirements for other countries are usually contained in that country's Aeronautical Information Publication (AIP).

19 CFR Part 122 contains Advance Passenger Information System (APIS) regulations which require APIS manifests to be submitted to U.S. Customs and Border Protection (CBP) for all private aircraft arriving from or departing for a foreign port or place. APIS regulations also require that electronic notices of arrival and departure as well as electronic manifests relative to travelers (passengers and crew) be submitted to CBP within specific timeframes. For detailed information on the APIS regulations, see Advance Information on Private Aircraft Arriving and Departing the United States, 73 Fed. Reg. 68,295 (Nov. 18, 2008) (19 CFR 122.22). This publication, along with other resources, is available at

  1. All aircraft entering U.S. airspace from a foreign port or departing U.S. airspace for a foreign port must provide at least 1 hour advance notice to the U.S. Customs and Border Protection (CBP) via the Electronic APIS (eAPIS).
  2. Pilots of aircraft inbound to the U.S. from a foreign port are required to notify CBP of any changes to their ETA which are 15 minutes or greater. Upon pilot request, relay changes in ETA to CBP.
  1. Unless otherwise authorized by ATC, no person may operate an aircraft into, within, or across an ADIZ unless that person has filed a flight plan with an appropriate aeronautical facility.
  2. Unless otherwise authorized by ATC, no person may operate an aircraft into, within, or across an ADIZ unless that aircraft is equipped with a coded radar beacon transponder and automatic pressure altitude reporting equipment having altitude reporting capability that automatically replies to interrogations by transmitting pressure altitude information in 100-foot increments.


This paragraph does not apply to the operation of an aircraft which was not originally certificated with an engine-driven electrical system and which has not subsequently been certified with such a system installed; for example, a balloon or glider.

  1. A person who operates a civil aircraft into an ADIZ must have a functioning two-way radio, and the pilot must maintain a continuous listening watch on the appropriate aeronautical facility's frequency.
  2. Pilots of aircraft entering or departing the United States through an ADIZ, or operating within an ADIZ, are required to comply with the provisions of 14 CFR 99.
  3. Forward information on DVFR aircraft inbound to the U.S. to NORAD via Service B or by telephone. Forward the following information:
  1. Aircraft call sign.
  2. Number and type of aircraft.
  3. Altitude (within ADIZ).
  4. True airspeed.
  5. Time of departure.
  6. Point of departure.
  7. Destination.
  8. ETA.
  9. Remarks: DVFR discrete transponder code; estimated first point of penetration of ADIZ (latitude/longitude or fix-radial-distance); estimated time of penetration of ADIZ.
