Leasing is categorized by the FAA into two types of arrangements, the “Wet” Lease & the “Dry” Lease.
A Wet Lease is one in which the Lessor provides both the aircraft and the crew. Leasing of an aircraft without the crew by the Lessor is considered a Dry Lease.
An important aspect of the Dry Lease is the Lessee has operational control of the aircraft. The Lessee (not the aircraft owner) is responsible for determining if a flight should be conducted based on the many factors that must be considered such as departure and arrival airports, weather, length of flight etc. The crew hired by the Lessee can provide guidance and recommendations on each aspect of the flight, however, the final determination and operation of the flight is the responsibility of the Lessee.
