Fokker D.I (English)

The Fokker D.I

The Fokker D.I was a fighter aircraft from the First World War.
Contrary to what the name suggests, the DI (M.18ZF / M.18ZK) was the successor to the D.II (M.17ZF / M.17ZK).
Both Fokkers entered service simultaneously with the German army, which received the first ninety aircraft around July/August 1916.
Another sixteen D.Is went to the Austro-Hungarian aviation forces.
The D.I had ailerons in the wing or wing warping system.
The D.I had one Spandau LMG.08/15 machine gun and was equipped with a six-cylinder 120 hp Mercedes D II inline engine.
The D.I would serve as the basis for the D.III and the D.IV.
The aircraft was also built under license at MAG, Magyar Általános Gépgyár, (General Hungarian Machine Factory) in Hungary, among others for the Austro-Hungarian Army.

The 04.15 of the Austro-Hungarian army on 17-01-1917, this D.I was built under license at MAG in Hungary. To give an idea of what the pilots had to endure, besides the misery of the war: Suppose it was 10 degrees below zero here on the ground. The temperature drops by about 1 degree per 100 m altitude. So at 2,500 m the temperature was around minus 35 degrees Celsius. The 'windchill' by the airspeed of the aircraft made it feel like minus 50 to minus 60 C for the pilots.
