The modification works of the IL-62 long-range passenger airplane began in 1969. Finally the airplane was equipped with a
more efficient turbojet engines designed by P.A.Soloviev. The engines were installed inside the nacelles that had improved
aerodynamic shape. There was an additional fuel tank installed inside the airplane fin, and that modification increased the
airplane flight range. The IL-62M airplane cruising speed finally increased, and the more effective double-slotted flaps
allowed to reduce landing speed. The modified airplane was equipped with the luggage power-driven loading system, the modified
stabilizer control system, the new steering control wheels (in order to improve vision for pilots and to provide for the
standard instruments location at the pilots control panel), the improved auxiliary power plant designed for both the main
engines start and cabin air conditioning.
The IL-62M began its regular passenger operations on January 8, 1974, and it remains in operation till now.
The IL-62M has the Aircraft Operational Certificate.
