I understand the MoD now require pilots visiting their <our> bases to obtain an "Insurance Waiver Certificate" if we are to use the Crown Indemnity cover if we may have it already with our normal a/c policy - for more than 12 visits per year. I am in the process of applying for such a certificate and once have received such will update this thread. However as I understand it so far it is a case of asking the RAF to send an application form which then (once returned) is submitted for security clearance. Only "originals" of the form are accepted so if applying on behalf of a syndicate ask for several forms. I am advised the clearance can take up to 3 months. Nicely there is no charge associated with all this.
