Small UAS flights below 400 ft will no longer be notified

Following recent updates to the Air Navigation Order for small Unmanned Aircraft Systems (SUAS) we have reviewed the process for the notification of SUAS flights.

Subsequently we will no longer issue NOTAM for SUAS flights below 400ft AGL. This decision follows engagement with key stakeholders and the use of risk analysis tools and safety data. It does not affect

  • the requirements for UAS operators to follow the NATS NSF and ENSF process.
  • the ability for aerodromes to promulgate NOTAM’s within their associated areas should they deem necessary.

Any SUAS operators with exemptions to operate higher than 400ft AGL will be required to inform the CAA, Airspace Regulation, to enable NOTAM to be published.

Pilots are reminded to remain vigilant whilst operating both inside and outside the London and City CTR due to the increase in UAS operations.
