Air Navigation Order 2016 Drone Penalties Explained

How ANO 2016 Penalties Work

The Air Navigation Order 2016 (ANO 2016) is the principal piece of secondary legislation governing aviation — including unmanned aircraft — in the UK. Penalties for breaches vary significantly depending on the seriousness of the offence, ranging from administrative fixed penalty notices to custodial sentences imposed by the courts.

Penalties fall into two broad categories: criminal penalties imposed following prosecution, and administrative sanctions applied by the CAA without court proceedings.

Criminal Penalties by Offence Category

Endangering Aircraft Safety (Article 240)

This is the most serious drone-related offence under the ANO 2016. An operator who recklessly or negligently causes an aircraft to be endangered faces:

• On indictment: an unlimited fine and up to five years' imprisonment
• Summary conviction: a fine up to the statutory maximum

Courts treat this offence with particular gravity when manned aircraft were endangered, especially near airports or in controlled airspace.

Flight Restriction Zone Breaches (Articles 94A–94B)

Flying a drone within a Flight Restriction Zone (FRZ) around a protected aerodrome without authorisation carries the same maximum penalties as endangering an aircraft: up to an unlimited fine and five years' imprisonment on indictment. These provisions were introduced following incidents that caused significant disruption to airport operations.

Operating Without Registration or ID (Article 265 and Related)

Failing to register as a drone operator or obtain the required Flyer ID when legally obliged to do so is an offence. The penalties on summary conviction include a fine. In practice, the CAA typically addresses first-time breaches through fixed penalty notices rather than prosecution.

Breaching Flying Conditions (Articles 94, 94C–94F)

Contraventions of specific flying conditions — such as altitude limits, distance rules, or requirements for maintaining visual line of sight — are offences under the ANO 2016. On summary conviction, penalties include a fine. The level of the fine depends on the specific provision contravened and the circumstances.

CAA Fixed Penalty Notices

The CAA has the power to issue fixed penalty notices (FPNs) for certain drone offences as an alternative to prosecution. FPNs provide a quicker resolution for less serious breaches and allow operators to discharge their liability by paying a specified amount.

Key points about FPNs:

• They are offered at the CAA's discretion as an alternative to prosecution
• Accepting an FPN does not create a criminal record
• If an operator declines to pay, the CAA may then proceed with prosecution
• The amounts are set by regulation and vary by offence

Factors That Influence Sentencing

When a case proceeds to court, sentencing judges consider several factors:

• Proximity to manned aircraft: near-misses with passenger aircraft attract the highest penalties
• Intent: deliberate or reckless conduct is treated more severely than negligent behaviour
• Location: offences near airports, in controlled airspace, or over crowds are viewed more seriously
• Previous conduct: repeat offenders face escalating penalties
• Cooperation: cooperation with investigators and early guilty pleas may result in reduced sentences

Comparison: Fixed Penalty vs. Court Prosecution

For many lower-level breaches, operators have a choice: accept the CAA's fixed penalty notice or contest the matter in court. Accepting the FPN closes the matter without a criminal record. Contesting it means the CAA must prove the offence to the criminal standard of proof (beyond reasonable doubt), but a conviction carries a criminal record and potentially higher financial penalties.
