• Large model aircraft

    Model aircraft with a mass of more than 20kg are termed 'Large Model Aircraft'. Within the UK, large model aircraft may only be flown in accordance with an exemption from the ANO, which must be issued by the CAA.

    Form SRG1307 must be completed and returned to the UAS unit, who will process the application. CAP658 Chapter 3 provides further guidance. In due course, CAP 658 will be superseded by a new volume of CAP722. 

    Anyone wishing to build a large model aircraft should engage early with the Large Model Association (LMA). The LMA operates a model inspection scheme, and once satisfied, will issue a certificate of design and construction. This certificate must accompany the SRG1307 application for an exemption. Applications made without such a certificate will be rejected. 

    Model aircraft displays

    Model aircraft operating in a display, above 400ft from the surface require a permission as set out in Article 94A(2), and if over 20Kg also require an exemption from the ANO. Both of these can be provided within the SRG 1308 process.

    Form SRG1308 must be completed and returned to the UAS unit, who will process the application. CAP 658 provides further guidance. In due course, CAP 658 will be superseded by a new volume of CAP722.
