Air India One
Air India One (also referred to as AI-1 or AIC001) is the call sign of any Air India aircraft carrying the Prime Minister of India, President of India or the Vice President of India. Air India is the national airline of India. The aircraft are operated as VIP flights by the Indian Air Force (IAF). The IAF's Air Headquarters Communications Squadron, based at Indira Gandhi International Airport (formerly Palam Air Force Base) in New Delhi, is in charge of operating these aircraft.
Apart from the Boeing 747-400 owned by Air India and used on international state visits, the IAF currently owns four 14 seater Embraer 135 and three customized 46 seater Boeing Business Jets (BBJ) that have a VIP cabin and are used for VIP movement. Of these the Boeing 747s are used by either the Prime Minister,President or Vice President when on official overseas visits.
Each Embraer 135 is equipped with missile-deflecting systems, modern flight management system including global positioning system, as well as category II instrument landing system. These aircraft cost the IAF 1.40 billion each. The Three BBJs, christened Rajdoot, Rajhans and Rajkamal cost the IAF 9.34 billion each ( 7.34 billion for the actual aircraft plus an additional 2 billion for Self Protection Suites). Self-protection suites include radar warning receivers, missile-approach warning and counter-measure systems. The aircraft have the capability to shoot chaff and flares to deviate radar-guided and heat-seeking missiles off their track along with other security tools.The other security instruments are undisclosed by the Indian Air Force.
The onboard electronics include about 238 miles of wiring (twice the amount you'd find in a normal 747). Heavy shielding is tough enough to protect the wiring and crucial electronics from the electromagnetic pulse associated with a nuclear blast.
The President is designated VIP 1, The Vice President VIP 2 and The Prime Minister VIP 3. The BBJ have a four class configuration. For the President/Prime Minister, there is a separate enclosure in the aircraft which includes an office and a bedroom. Everyone aboard Air India One is required to wear a color-coded identity card. Members of the official delegation (Joint Secretary level and above) are tagged in purple and sit in First Class while accompanying officials (junior officers) are given pink tags and sit in Business Class on the upper deck. Journalists and others from the media sit in the Executive Class and sport yellow tags. Support staff join the security team in a small economy class section at the back of the aircraft and are tagged in red. These aircraft are expected to be replaced as they have become less cost-effective to operate.The Indian Air Force is looking forward to replace the present Boeing 747-400 with the Boeing 777-300, 787-9 or the Airbus A380. Most probably three new Boeing 777-300ERs will be the successors of the present B747s.
