Ferry flying
Ferry flying is the flying of aircraft for the purpose of returning to base, delivery to a customer, moving from one base of operations to another or moving to or from a maintenance facility for maintenance, repair, and operations. A commercial airliner may need to be moved from one airport to another to satisfy the next day's timetable or facilitate routine maintenance. This is commonly known as a positioning flight or repositioning flight, and may carry revenue freight or passengers as local aviation regulations and airline policies allow. Such flights may be necessary following a major weather event or other similar disruption which causes multiple cancellations across an airline's network resulting in many aircraft and crew being out of position for normal operations; the 2010 eruptions of Eyjafjallajökull or the mass evacuation of US airspace following the 9/11 attacks being significant examples of this. Ferry permit
A ferry permit is a written authorization issued by a National Airworthiness Authority to move a non-airworthy civil aircraft from its present location to a maintenance facility to be inspected, repaired and returned to an airworthy state. Ferry pilots
