This is a list of aviation-related events from 1917.

Events During her 30 November 1916 – 24 February 1918 cruise, the Imperial German Navy commerce raider carries a Friedrichshafen FF.33e seaplane nicknamed Wölfchen ("Little Wolf" or "Wolf Cub"), which during 1917 singlehandedly captures at least four of the 37 enemy ships Wolf captures and sinks during her cruise. Wölfchen makes between 54 and 56 flights, the most by any World War I shipboard aircraft.Layman, R.D., Before the Aircraft Carrier: The Development of Aviation Vessels 1849-1922, Annapolis, Maryland: Naval Institute Press, 1989, , p. 30.

January The Luftstreitkrafte (German Air Force) disbands three Kampfgeschwader (bomber wings) and redesignates their squadrons as Schutzstaffeln (escort squadrons).

The United States Army forms the 7th Aero Squadron for service in the Panama Canal Zone. February 7 – Suffering progressive damage due to a series of crashes in bad visibility and poor weather, the Imperial German Navy Zeppelin L 36 finally crashes onto the Aller river and is destroyed by high winds.

February 13 – Over the Gulf of Mexico off Pensacola, Florida, United States Marine Corps aviator Francis Thomas Evans, Sr., performs an aerobatic loop in a Curtiss N-9 floatplane, becoming the first person to loop a seaplane – a feat previously believed impossible in an N-9 even by the N-9s manufacturer. He will receive a Distinguished Flying Cross for the achievement in 1936. However, the recovery techniques he discovers when the N-9 stalls and spins – previously thought impossible to recover from in an N-9 – during some of the days loop attempts prove of far greater importance and have been in use ever since.Knapp, Walter, "The Marines Take Wing," Aviation History, May 2012, pp. 51-52.

March Royal Naval Air Service Handley Page O/100 bombers begin night attacks on German naval bases, railway stations and railway junctions, and industrial targets.Crosby, Francis, The Complete Guide to Fighters & Bombers of the World: An Illustrated History of the Worlds Greatest Military Aircraft, From the Pioneering Days of Air Fighting in World War I Through the Jet Fighters and Stealth Bombers of the Present Day, London: Anness Publishing Ltd., 2006, , p. 263. United States Navy Lieutenant Kenneth Whiting proposes to Secretary of the Navy Josephus Daniels that the Navy acquire a ship with an aircraft catapult and a flight deck. Although rejected on June 20, it is the first serious U.S. Navy consideration given to acquisition of an aviation ship since the American Civil War (1861–1865).Layman, R.D., Before the Aircraft Carrier: The Development of Aviation Vessels 1849-1922, Annapolis, Maryland: Naval Institute Press, 1989, , p. 116. March 8 – Count Ferdinand von Zeppelin, inventor of the practical dirigible, dies.Phythyon, John R., Jr., Great War at Sea: Zeppelins, Virginia Beach, Virginia: Avalanche Press, Inc., 2007, p. 7. March 13 – The United States Armys 6th Aero Squadron is organized in the Territory of Hawaii, operating three Curtiss N-9 seaplanes.Aviation Hawaii: 1879-1919 Chronology of Aviation in Hawaii March 16–17 (overnight) – The German Naval Airship Service attempts to bomb England for the first time in 1917, in the first use of new Zeppelins designed for high-altitude flight that the Services commander, Peter Strasser, believes will be too high for British air defenses to reach. The five Zeppelins – at least three of which achieve altitudes of between – mostly bomb open countryside and do only £79 in damage and kill no one. Disabled by mechanical failure, L 39 drifts over Compiègne, France, and is shot down by French antiaircraft guns with the loss of her entire crew, and L 35 is badly damaged while landing in Germany. The success of the Zeppelins in reaching high altitudes during a bombing raid encourages Strasser, who accompanies the raid aboard L 42, to plan a new bombing offensive.Whitehouse, Arch, The Zeppelin Fighters, New York: Ace Books, 1966, no ISBN, pp. 190-193. March 21 – The world's first drone flight takes place when an unmanned de Havilland monoplane aerial target aircraft with a wingspan is launched off a pneumatically powered ramp at the Royal Flying Corps base at Upavon in Wiltshire, England, and flies briefly under radio control from the ground by Henry Segrave.Professor A. M. Low, "The First Guided Missile," FLIGHT, 3 October 1952, p. 436. Dozens of generals from Allied countries — probably in England for the Imperial War Conference — witness the flight.Steve Mills, The Dawn of the Drone, Casemate Publishers, 2019. Dr. Archibald Low, the officer commanding the secret RFC Experimental Works in Feltham, Middlesex, had invented the control system.

April Known as Bloody April. The Royal Flying Corps, while supporting the Arras offensive, loses 245 aircraft—140 in the first two weeks—out of an initial strength of 365. Aircrew casualties are 211 killed or missing and 108 captured. The opposing Germans lose only 66 aircraft.Blumberg, Arnold, "The First Ground-Pounders," Aviation History, November 2014, p. 40.

April 6 The United States enters World War I, declaring war on the German Empire. United States Marine Corps aviation has a total strength of seven officers and 43 enlisted men.Butler, Glen, Colonel, USMC, "That Other Air Service Centennial," Naval History, June 2012, p. 56. April 13 – Royal Naval Air Service flying boats begin flying "Spider Web" patrols over the North Sea in the vicinity of the North Hinder light ship to detect German submarines in the area. The new patrol pattern, resembling a spider web, allows four aircraft to search a 4,000-square-mile (10,000-square-kilometer) area in about five hours, only half the time it takes a surfaced submarine to transit the area. The flying boats make 27 patrols in the next 18 days, sight eight German submarines, and make bombing attacks against three of them.Allward, Maurice, An Illustrated History of Seaplanes and Flying Boats, New York: Dorset Press, 1981, , p. 27.Terraine, John, The U-Boat Wars 1916-1945, New York: Henry Holt and Company, 1989, , p. 74.

Under fire from hundreds of British rifles and machine guns, he and his pilot spray the British trenches with 500 rounds of ammunition before a hit in their engine forces them to withdraw. The incident represents the birth of close air support as a mission of the world's air forces.Blumberg, Arnold, "The First Ground-Pounders," Aviation History, November 2014, pp. 41-42.
