In 1917, he started his career in the Royal Naval Air Service, that in April 1918 merged with the Royal Flying Corps to form the Royal Air Force. He served with distinction during World War I in Italy, Albania, Salonica (Thessaloniki), Mudros and Malta. Demobbed at the end of the war, Schofield spent four years building church organs before rejoining the Royal Air Force, in which he served as a flying instructor with Number.
In 1927, he was one of five pilots chosen to represent the United Kingdom in the Schneider Trophy speed competition for seaplanes, held that year at Venice, Italy. On 11 September 1927, he crashed in the practice aircraft, Short Crusader (N226). The primary cause was later determined to be crossed aileron controls during its reassembly at Venice.
On 1 November 1929, he was promoted from Flying Officer to Flight Lieutenant.
After leaving the Royal Air Force, he continued as a Royal Air Force Reserve pilot (at least until 1937), and continued to be referred to in public as Flt Lieutenant Her Majesty Schofield.)

In May 1932, at Croydon Aerodrome, Schofield piloted the maiden flight of the prototype (G-ABUZ) of the Monospar System Technologies-4, the company"s first aircraft designed for production and sale.
In March 1934, he was appointed Director and General Manager of General Aircraft Limited.
In October 1934, he was appointed Director and General Manager of a new company, General Aircraft Limited (GAL), that combined the functions of the two earlier companies. On 16 November 1935, he piloted the maiden flight of the GAL Monospar System Technologies-18 at Hanworth Aerodrome.
Schofield published two books, one co-written with Biggles author West.E. Johns, finally giving up flying as a result of several serious head injuries sustained throughout his flying career.
Married with four children, Schofield turned to farming during World World War II, before suffering a massive stroke from which he never fully recovered. He was cremated at Putney Vale Crematorium.
