Heavy military transport aircraft Il-76MD-90A is an upgraded version of the famous aircraft Il-76MD that had once been manufactured in the Republic of Uzbekistan at the Tashkent factory named after Chkalov. The new integrated flight and navigation system, the automatic control system, the communications system and the “glass cabin” comply with all up-to-date aircraft avionics requirements and significantly increase the flight safety, navigation and cargo/troop parachute dropping accuracy. Replacement of standard D-30KP2 engines with much more up-to-date PS-90A-76 ones, installation of a modified wing and a reinforced landing gear significantly extend the aircraft performance.

Originally developed by: “Aviation Complex named after S.V. Ilyushin”, Russia
The heavy strategic military transport aircraft Il-76MD-90A is designed for inter-regional transportation of troops, heavy long-size vehicles and cargoes as well as for cargo/heavy vehicles/troops parachute dropping and air-mission landing. The aircraft transports the whole list of military equipment used by airborne troops of Russia. IL76MD-90A can be also used for transportation of ill and injured people and for fire-extinguishing purposes.
The maximum payload has been increased up to 52 tons.
The maximum takeoff weight has been increased to reach 210 tons.
The aircraft is a cantilever high-wing monoplane with four engines located on the wing pylons. It has a Tee-tail unit and a 5 leg-landing gear. A cargo compartment is located in the fuselage tail bottom section. It has a ramp for loading/unloading cargoes and equipment and for parachute dropping purposes.
The aircraft can perform takeoff and landing on unpaved airfields (with consistency of the soil up to 7.5 kg/cm2) and on concrete pavement airfields with altitude above sea level pending from minus 300 up to 3000 m and perform flights day and night over land and sea.
The aircraft upgrading envisaging installation of up-to-date engines, aircraft control systems, a new wing and a reinforced landing gear extends the Il-76MD-90A aircraft performance and increases the navigation and parachute dropping accuracy.

Aircraft of a new generation
The main design features of aircraft Il-76MD-90A are as follows:

• The PS-90A-76 engines are installed;
  
• The new wing – long-size panels are used;
  
• The fuel system is modified for a new wing;
  
• The new “Kupol-III-76M” flight sight navigation system with a display indication is installed;
  
• The digital САУ-76 auto flight control system is installed;
  
• The КСЭИС-КН-76 aircraft status master monitor display system with 8 МФИs (multifunctional indicators) is installed to provide indication of aircraft systems parameters, those of pilot and navigation parameters and of САУ-76;
  
• The aircraft systems to provide installation of the PS-90A-76 engine and indication and control are modified;
  
• The APU TA-12A is installed
  

Using the state-of-the-art PS-90A-76 engines of the fourth generation makes it possible to increase significantly the operation efficiency of the aircraft due to:

• reduction of the specific fuel consumption by 12%
  
• flight range increase by 18%
  
• reduction of the direct operation costs
  
• possibility of aircraft operation on the aerodromes high in the mountains and at high temperatures
  
• compliance of noise and emission levels with up-to-date ICAO requirements
  

Cockpit and integrated flight and navigation system
The “glass cabin” principle has been realized in the aircraft. Eight multifunctional LC displays and three intelligent control panels have been installed in the cockpit. The glass cockpit provides for excellent view from the pilot and navigator work stations. The new “Kupol-III-76M” flight sight navigation system is installed in the Il-76MD-90 aircraft to provide for solving navigation problems and intended for:
work with navigation data bases also including the global base: when preparing the flight plan, during en-route flight, when maneuvering in the aerodrome area and during approach (SID/STAR, APPR);
automation in solving navigation problems ensuring automated flight along the pre-planned path using autonomous and non-autonomous correction means;
providing aircraft traffic collision avoidance;
automatic approach according to category II to aerodromes equipped with landing facilities corresponding to ICAO category II;
detection, identification with the help of weather radar and display on the integrated navigation status indicator the weather conditions in horizontal and vertical sections including the four color indication of precipitation intensity and turbulence in accordance with the ARINC-708A recommendations, detection of mountain peaks, big cities, detection of encountering aircraft by a passive method, detection and tracing of radar beacons, providing the inter-aircraft navigation mode;
providing the system automated control on the land and in the flight.

AERIAL-DELIVERY SYSTEM
The aerial-delivery system is installed to ensure the aircraft operation in the following conditions:

• for transportation of troops
  
• for troop parachute dropping
  
• for transportation of cargoes, equipment, universal sea and aviation cargo containers and pallets
  
• for cargo and equipment parachute dropping on the platforms
  
• for cargo free dropping
  

The cargoes and equipment are loaded through the cargo door by means of airborne winches and electric overhead monorail motor hoists. Two winches ensure loading the dumb wheel equipment with maximum force on each winch cable to make up 3000 kgf. The winches are driven electrically and manually. The loading of a cargo item can be done with four hoists weighing up to 10 tons.
The cargo cabin has a ramp, which can be moved to horizontal or some other necessary position during loading and unloading operations. If needed, some cargoes weighing up to 30 tons can be lifted to the cargo cabin by means of a ramp. To load caterpillar and wheel vehicles as well as a platform, four under-ladder devices are to be installed onto the ramp to provide a smooth entering of the vehicles onto the ramp. Four roller ways are to be installed onto the cargo cabin and ramp floor with a monorail in two variants: in special niches for platform parachute dropping; onto the beams for transportation of aviation containers and pallets.
For carrying of people there are seats in the cargo cabin and the removable central seats can be installed. In the one-deck variant (with central seats) the aircraft can carry 145 military men or 126 parachutists. In the two-deck variant it can carry up to 225 military men.
The aircraft is equipped with the cargo dropping system that allows a single and serial dropping of platforms loaded with cargoes and equipment.

Besides that, in the cargo cabin some special equipment can be installed to ensure:

• carrying of up to 114 injured people and the medical personnel
  
• providing intensive therapy for up to 20 badly wounded people
  
• fire extinguishing
