The operation record books provide a comprehensive record of operations, patrols, training flights etc in war time. Listing targets attacked and unit losses, many include names of those involved in operations, and individual aircraft by serial number. In peacetime they provide a record of the units daily activities such as visits from other units, visits by the unit involved, visits by people the compiler of the record deems worthy of inclusion. There is normally a record of the weather that day, details of sporting activities. Summary of event forms (also known as Form 540) Squadrons are the main form of flying unit of the Royal Air Force (RAF). These include Royal Flying Corps (RFC) and Royal Naval Air Service (RNAS) squadrons incorporated into the RAF when it was formed on 1 April 1918, during the First World War. Other squadrons of the RAF include those from Commonwealth air forces which have served within the RAF structure and squadrons of the Fleet Air Arm before it transferred to the Royal Navy in 1939. Active squadrons are the full and part-time units of personnel and equipment that carry out the RAF's mission. RAF squadrons can fly aircraft or be ground based carrying out many different roles.
