Miles Monarch
View on Wikipedia
The Miles M.17 Monarch was a British, light, touring aeroplane of the 1930s. It was a single-engine, three-seat, cabin monoplane with a fixed, tailwheel undercarriage.
Key Information
Development
[edit]The last civil type produced by Phillips and Powis before the war, the Monarch was a development of their earlier Whitney Straight. Compared to its sibling. the Monarch had an enlarged fuselage, allowing provision of a third seat in part of what had been the luggage space.
Operational history
[edit]Eleven aircraft were built between 1938 and 1939, six of these to British customers, the rest going to export.
On the outbreak of war five of the British-registered machines were impressed by the Air Ministry; one machine belonging to Rolls-Royce acquired camouflage paint but remained in its owner's service. All but one of these survived the war, though a Dutch-registered aeroplane (PH-ATP) was destroyed in the Luftwaffe raid on Schiphol on 10 May 1940. One aircraft, OY-DIO, was on the Danish register until 9 Sept. 1939 and owned by a Dane named Hagedorn.
In the 1950s, one Monarch (G-AIDE) enjoyed some success as a racer in the hands of W.P. Bowles
For the most part, the remaining Monarchs led uneventful but useful careers; a number survived into the Sixties. G-AFJU is displayed at the National Museum of Flight at RAF East Fortune near East Linton, Scotland.
