CAA Flying Unit Doves
In the 1950s and 1960s the Ministry of Transport and Civil Aviation (then Board of Trade, then CAA) operated Doves for pilot licensing testing and airport navigational aid calibration.
Is there anyone lurking on this forum who flew Doves with the CAAFU or who flew a Dove whilst being tested by the CAA? I'd love to learn more about this aspect of civil aviation, ideally from someone first-hand.
