With a dry lease, the lessor provides the aircraft without crew. These arrangements are favored by leasing companies and banks, and require the lessee to put the aircraft on its own AOC and provide aircraft registration. Dry leases usually cover a term of no less than two years. Lessees must comply with conditions regarding maintenance, insurance, and depreciation, and other requirements that may be affected by geographical location, political circumstances or other factors.
