The AVRO 504K was a great flyer, and the standard allied WWI trainer. The Danish Navy owned six from 1921 to 1931.

Det Danske Luftfartselskab (Danish Airline Company) purchased two AVRO 504K in Britain during 1919, but they were never used and later sold on to the Royal Danish Army. The army acquired an additional two aircraft, and they were used until 1931. The Royal Danish Navy purchased six during 1920. A total of 5 crashes, but were substituted for the 504N.

The aircraft were flown with the typical AVRO landing gear, as well as with floats.

Some websites says the length was 29 ft, the original manufacturing drawings say 28’11”, and other sources say 29’5″. Some, like Windsock Datafile No. 28 says both.
