Public Aircraft Operations

AIM ¶ 11-4-3 Public Aircraft Operations

AIM 11-4-3 explains how government entities qualify for Public Aircraft Operations (PAO), COA requirements, and UAS access to the NAS for pilot students.

In Plain English

AIM 11-4-3 covers how governmental entities gain airspace access for Public Aircraft Operations (PAOs), especially with UAS. To qualify, the operator must be a government body (state, D.C., territory, or political subdivision) defined under 49 USC 40102(a)(41), and the flight must serve a governmental function under 49 USC 40125.

Qualifying government functions include:

  • National defense and intelligence
  • Firefighting, search and rescue
  • Law enforcement (including prisoner/detainee transport)
  • Aeronautical research
  • Biological or geopolitical resource management

Key points for students:

  • Aircraft must be government-owned or exclusively leased for 90+ continuous days.
  • Operations "for the public good" don't automatically qualify — most volunteer fire departments don't meet PAO criteria.
  • Commercial purposes (e.g., a police UAS shooting a promo video) disqualify the flight from PAO status.

To get airspace access, the entity must:

  1. Submit a Public Declaration Letter (PDL) (federal agencies are exempt) reviewed by FAA general counsel.
  2. Once recognized, request a Certificate of Authorization (COA) via CAPS or DroneZone.

A PAO COA permits blanket UAS operations in Class G airspace across the continental U.S., including night ops with proper lighting and training. Waivers can extend privileges further. Note: the AIM is informational; the underlying statutes and the COA itself are what bind operations.

FAA AIM ¶ 11-4-3
11-4-3. 11-4-3. Airspace Access for Public Aircraft Operations (PAOs) General requirements for PAO status. Governmental entities, as defined by federal law 49 USC 40102(a)(41), Definitions, can fly as a public aircraft operation as long as the flight meets the definition of a governmental function 49 USC 40125, Qualifications for Public Aircraft Status. Public aircraft are aircraft owned and operated by the government of a state, the District of Columbia, or a territory or possession of the United States, or a political subdivision of one of these governments, except as provided in 49 USC 40125(b), Qualifications for Public Aircraft Status. Public aircraft can also be aircraft exclusively leased for at least 90 continuous days by the government of a state, the District of Columbia, or a territory or possession of the United States or a political subdivision of one of these governments, except as provided in 49 USC 40125(b), Qualifications for Public Aircraft Status. NOTE- The term “government function” refers to one of several activities undertaken by a government, such as national defense, intelligence missions, firefighting, search and rescue, law enforcement (including transportation of prisoners, detainees, and illegal aliens), aeronautical research, or biological or geopolitical resource management. An operation “for the public good” does not necessarily meet the qualifications for a public operation; for example, most volunteer fire departments in the United States will not qualify as PAOs. Public safety organizations often conduct operations under 14 CFR part 107, as well as public aircraft operations. REFERENCE- 49 USC 40102, Definitions. 49 USC 40125, Qualifications for Pubic Aircraft Status. A PAO is conducted under certain 14 CFR part 91, UAS Operations Rules, with a COA granted to allow access to the NAS. A PAO COA allows blanket UAS operations in Class G airspace throughout the entire continental United States, including operations at night with appropriate lighting and training, for the duration of the COA. Waivers and/or authorizations to the COA can permit operations beyond the basic COA. Operating as a PAO requires adherence to specific conditions as directed in the COA. Operations under the public aircraft statute cannot include purposes that are not governmental functions. For example, a police UAS flying without remuneration to obtain footage for a department promotional video would not be a governmental function. COA Application Process: Public Declaration Letter (PDL). The first step in getting a PAO COA is to be recognized as an authorized government agency by submitting a PDL that shows the organization is indeed a governmental entity as defined by federal law. FAA general counsel reviews this letter, which is usually issued by a city, county, or state attorney Federal agencies are deemed to be governmental entities without submitting a PDL. COA Request. If formally recognized as a governmental entity under federal law, entities are given access to the COA Application Process System (CAPS) or DroneZone, where a request for a PAO COA may be submitted. Operating as a PAO requires you to adhere to specific conditions as directed in your COA. Remember that an aircraft described in subparagraph (a), (b), (c), or (d) of 49 USC 40102(a)(41), Definitions, does not qualify as a public aircraft under such section when the aircraft is used for commercial purposes (e.g., performing a non-governmental function) .

Oral Exam Questions a DPE Might Ask
Q1What two basic conditions must be met for a flight to qualify as a Public Aircraft Operation?
Per AIM 11-4-3, the operator must be a governmental entity as defined by 49 USC 40102(a)(41), and the flight must meet the definition of a governmental function under 49 USC 40125 (e.g., law enforcement, SAR, firefighting, defense).
Q2What does a PAO COA authorize for UAS operations, and where?
Per AIM 11-4-3, a PAO COA allows blanket UAS operations in Class G airspace throughout the entire continental United States, including night operations with appropriate lighting and training, for the duration of the COA. Waivers or authorizations can permit operations beyond the basic COA.
Q3What is a Public Declaration Letter (PDL) and who must submit one?
Per AIM 11-4-3, a PDL is the first step in obtaining a PAO COA — it demonstrates the organization is a governmental entity under federal law. It is typically issued by a city, county, or state attorney and reviewed by FAA general counsel. Federal agencies are deemed governmental entities and don't need to submit a PDL.
