Safeguarding at our airports


Cranes can cause a serious hazard to flight safety. They can penetrate the protected surfaces around an airport. These are designed to protect safe operation.

Cranes can affect an airport’s:

  • Instrument Flight Procedures (IFPs)
  • Obstacle Limitation Surfaces (OLS)
  • Communication, Navigation and Surveillance (CNS) facilities such as navigational aids or radar.

To reduce flight safety risks, anyone operating a crane or tall construction equipment in the area of a HIAL airport will require a permit. Crane or construction equipment under 10m high or surrounded by trees or structures that are taller are exempt.

Operators must provide ten days’ notice to airports prior to using a crane or other tall construction equipment. This is to allow the relevant assessments to be carried out. However, we do appreciate there may be circumstances where emergency crane hire is required. In these circumstances we will endeavour to process your application as soon as possible.

If the initial assessment highlights an impact, further detailed assessment will be required. This requires consultation with external agencies and could extend the time to grant a permit.

As per British Standard 7121 ‘Code of Practice for Safe Use of Cranes’ - Crane control in the vicinity of aerodromes - crane operator(s) are required to consult with aerodromes for permission to work if a crane is to be used within 6km of the aerodrome and its height exceeds 10 metres or that of surrounding structures or trees.

Apply for a crane permit.

The crane permit application form offers guidance on how to complete. However, if you require support, please get in touch with the safeguarding team at

The information we collect is required to allow us to meet our (EU) 73/2010 Aeronautical Data and Information Quality regulation. It enables us to maintain a safe operation whilst the crane is in operation, through liaison with our Air Traffic Control (ATC) unit. It will not be used for any other purpose.

Please see our privacy policy for more information.


Crane Permits are charged at a fixed fee of £295 (subject to annual review). Any extensions to the date/time of a permit or for a repeat operation of a previously approved permit (where all other information is the same) there will be a charge of £50 per application.
