Ilyushin Il-62M
role : long-range jet airliner
importance : ****
first flight : 1971 operational : March 1974 (Aeroflot)
country : Russia
NATO reporting name : CLASSIC
ICAO aircraft type designator : IL62
production : 193 aircraft
general information :
IL-62 version equipped with the more powerful Soloviev D-30KU turbofan, which allowed a higher MTOW. With an additional fuel tank in the tail, fuel capacity was increased with 5000 litre. This gave it an intercontinental range and allowed it to fly from Moscow to Havana no-stop. Probably because of the longer range, the number of passengers was reduced, so that they had more legroom. It was first publicly showed at the 1971 Paris air show.
CCCP-86673, the first IL-62M was on display at the Paris Air Show at Le Bourget in 1971 and in 1973. Here it is seen with number 454 on the 1973 Air Show.
Its dimensions are the same as those of the Il-62.
The Il-86MK is a high density version that can accommodate 198 passengers, first flight 1978. About 10 of this type were built.
The Il-62 is the largest airliner with manual flight controls, using steel cables and rods, pulleys, aerodynamic and weight balances, and trim tabs. Another key Il-62 trademark is the "saw tooth" ("dog-tooth") on the wing leading edge. This prominent feature acts as an aerodynamic fence vortex generator (without which the wings would be almost vortex-free), and fixed leading edge droop/slat/flap. It ensures vice-free behaviour at high angles of attack and assists efficient long-range cruise.
The engines have clamshell thrust reversers.
It has a containerized baggage container system; 14 containers empty weight 45 kg, each with capacity of 1.6m3 / 600 kg luggage. Total available freight volume : 48m3
The Il-62M stayed in service for long time, in 2016 the average age of the aircraft still in service was more then 32 years !

On 18 May 1989 a South African armed with a grenade, hijacked an Aeroflot IL-62 airliner carrying members of the African National Congress after take-off from Luanda, Angola. The hijacker was shot by a security guard as he attempted to enter the cockpit of the aircraft. The airplane continued to the planned stop at Dar Es Salaam, Tanzania.
The hijacker was sentenced to fifteen years in prison. (source : aviation safety net)

JOHANNESBURG, JUNE 2 -- The exiled African National Congress today accused South African police of sending white undercover agents to try to hijack a Soviet airliner flying from Angola to Tanzania last month with 174 black nationalist guerrillas aboard and force it to fly to Johannesburg. Two white South African men were said by Tanzanian officials to have been overpowered and disarmed by Soviet guards on the plane on May 18. A crew member was reported injured and one hijacker wounded by gunfire in the struggle. If the alleged attempted hijacking had been successful, it would have resulted in the largest mass arrest of ANC guerrillas ever, and would likely have provoked an international uproar and accusations of state-sponsored air piracy. Details of the incident remain sketchy and clouded in secrecy. The South African government denied complicity and suggested that ANC "dissidents" may have tried to hijack the plane because they wanted to return home. Soviet Embassy officials in Dar es Salaam have refused to comment, and the ANC headquarters in Lusaka, Zambia, had few details when contacted by telephone today. However, Tom Sebina, spokesman for the guerrilla movement, said South African police were responsible and that there was "a lot to suspect about" the men who were arrested aboard the plane. A 30-year-old South African, identified as Bradley Richard Stacey, was sentenced Thursday to 15 years' imprisonment in a court in the Tanzanian capital of Dar es Salaam after pleading guilty to charges that he took explosives, detonators and hand grenades aboard an Aeroflot Iluyshin airliner traveling from Luanda, Angola, to Dar es Salaam. According to news agency reports in Dar es Salaam, court officials said another, as yet unidentified, South African in a Tanzanian military hospital faces similar charges and will appear in court on June 13. The Soviet airliner reportedly was ferrying ANC guerrillas from training bases in Angola that were shut down as part of the Dec. 22 regional peace agreement between South Africa, Angola and Cuba. An estimated 7,000 ANC guerrillas in Angola are supposed to be moved to bases in Tanzania, Nigeria and Uganda as a result of the peace accord. A spokesman in the South African police command in Pretoria, Capt. R.A. Crewe, said he would not respond to "vaguely put allegations" but denied that there was any official involvement in the incident. Crewe referred to anonymous letters sent to several South African journalists last month, purporting to have been written by "dissident" ANC guerrillas, and said, "They correspond with our information that hundreds of ANC members are dissatisfied and don't want to go to those countries, but want to return home." ANC sources suggested that the letters, which claimed that many ANC guerrillas were resisting being transported from Angola to camps elsewhere in Africa, were forgeries mailed by the South African security police. On several occasions in recent years, the ANC's exile training bases have been infiltrated by white South African police agents posing as anti-apartheid activists. Some of them have been sent to the Soviet Union and to East Bloc countries for guerrilla training and have resurfaced in South Africa as senior security police officers.

Notes : of all classic jetliners : Longest technical life : 28.3 year ! due to its low flying hours/year : 2150 hour and longest average flying time : 4.15 hour/flight (design flight time). It has the lowest cycles in its category : 14650 ! so looks like totall different design philosophy. Lowest nr of flights per day : 1.42. Widest fuselage : 4.10m, biggest tyres : 145 cm diam...
Published landing distance 2800m, looks to high, calculated 2068m. According to Jane’s take-off distance 3000m, calculated 2756m.
