Loadmaster ACMP Alternating Current Motor Pump (Boeing Acronyms) Aircraft & Crew & Maintenance & Insurance ( A/C wet leasing)++/ Hide ACMI - Aircraft, Crew, Maintenance & Insurance WET LEASE The LESSOR provides the aircraft, crew (including their salaries and usually allowances), all maintenance for the aircraft and insurance. The LESSOR will charge for the block hour. The LESSEE has to provide all fuel, landing/handling/parking/storage fees, crew HOTAC including meals and transportation as well as visa fees, import duties where applicable as well as local taxes. LESSEE has to provide passenger/luggage and cargo insurance and in some cases need to cover the costs for War Risk. Furthermore the LESSEE has to pay the over flight/navigation charges. This point is a bit complicated. When flights are operating they use a flight number, which is issued to airlines by the ICAO. In order to cover the costs of air traffic control services, states over flown will send a bill to the owner of the flight number, which can be readily identified by its code. The aircraft owner will probably have a code, but will not want to use it because he will end up paying the bills. Therefore, an ACMI lease requires that the LESSEE provide his own flight number, so that the bills can be directed to them. Thus, an ACMI lease can usually only take place between two ICAO members states airlines unless other arrangements have been made between LESSOR and LESSEE. DAMP LEASE ACMI is similar as ACMI and wet leasing however usually without cabin crew. The LESSEE will provide the cabin crew. This can only be done if the cabin crew receives SEP (Safety and Emergency Procedures) training by the LESSOR, in order to be acquainted with the differences of the airplane. DRY LEASE is the lease of the basic aircraft without insurances, crew, maintenance etc. Usually dry lease is utilized by leasing companies and banks. A dry lease requires the LESSEE to put the aircraft on his own AOC and provide aircraft registration. A typical dry lease starts from two years onwards and bears certain conditions as far as depreciation, maintenance, insurances etc. are concerned. There are generally two types of dry lease, an Operating Lease and a Finance Lease. Operating Lease: generally a lease term that is short compared to the economic life of the aircraft being leased. An operating lease is commonly used to acquire aircraft for a term of 2-7 years. With an operating lease the aircraft doesn't appear on the Lessee's balance sheet. Finance Lease: also known as a capital lease, is defined when one of the following conditions are met: at the end of the lease term the Lessee has the option to purchase the aircraft at an agreed price. the lease payments are more than 90% of the market value of the aircraft. the term of the lease is over 75% of the aircraft's usable life. With a finance lease the aircraft appears on the Lessee's balance sheet, as it is viewed as a purchase.
