Mid-air scare as Sushma Swaraj's plane goes missing for 14 minutes

NEW DELHI: In a major scare on Saturday evening, an Indian Air Force aircraft 'Meghdoot' flying external affairs minister Sushma Swaraj from Trivandrum to Mauritius, on her way to South Africa, went incommunicado for 14 minutes. The scare happened when Mauritian air traffic control and the crew of the Embraer 135 Legacy flying Swaraj — which was cruising safely — could not establish contact with each other for some time after the plane entered the island nation's air space.



Mauritius then declared "INCERFA" alarm, which in aviation parlance means an uncertainty phase wherein it is not known if the aircraft and its occupants are safe.


Soon after the story was first reported by TOI website, the AAI put out a press release confirming that Mauritius had indeed activated INCERFA or the first stage of emergency which lasted from 4.44pm to 4.58pm. Swaraj was accompanied by senior MEA officials including Secretary (Economic Relations) TS Tirumurti.

印度时报网站报道这一消息后不久,印度机场管理局发布了一份新闻稿,确认毛里求斯确实启动了INCERFA或一级紧急状态,时间从从下午4点44分持续到4点58分。印度外交部官员包括外交秘书TS Tirumurti陪同斯瓦拉杰出访。

AAI said the plane took off from Trivandrum, where it had stopped for refuelling, at 2.08 pm for Mauritius. "Aircraft changed over from Indian airspace to Male ATC which then established contact with the aircraft at 4.44 pm IST. However, IFC 31 could not contact Mauritius ATC after entering Mauritius airspace. Mauritius ATC then activated INCERFA (the uncertainty phase). Later at 4.58pm IST, IFC 31 came in contact with Mauritius ATC and landed. Mauritius ATC activated INCERFA (uncertainty phase) without allowing the stipulated time period of 30 minutes to lapse from the time when aircraft last contacted ATC. This was perhaps done because the flight was carrying a VIP," said the AAI in its statement.


"Over oceanic airspace, air traffic control (ATC) globally waits for 30 minutes to sound INCERFA for a plane if it does not contact it on entering its airspace of flight information region. In this case, the Mauritius authorities pressed the alarm button 14 minutes after the flight IFC-31 entered its airspace and contact could not be established with the plane," said a senior official of Airports Authority India (AAI), the parent organisation for ATC here.


The pilots of the Embraer, for which the alarm was sounded at 4.44pm, contacted Mauritius ATC at 4.58pm, after which everyone heaved a sigh of relief. The Embraer does not have a long range and Sushma, who is flying it from India to South Africa to attend BRICS and India-Brazil-South Africa (IBSA) ministerial meetings, had to take three refuelling or technical stops — Delhi-Trivandrum-Mauritius-South Africa.


A senior ATC official said communication over oceanic area is often problematic due to erratic VHF communication. "Sometimes pilots are unable or forget to contact the Mauritius area. That oceanic area has no radar coverage and everything depends on VHF/HF communication. Such places where VHF coverage is not good are known as dark zones," said the official.


The 14-minute long uncertainty phase (INCERFA) is first of the three emergency phases under International Civil Aviation Organisation's Chicago Convention. The second is "alert phase" (ALERFA) in which apprehension exsts as to the safety of an aircraft and its occupants. The third is "distress phase" (DETRESFA) wherein there is a reasonable certainty that an aircraft and its occupants are threatened by grave and imminent danger and require immediate assistance.


Luckily, the 14-minute-long scare involving Swaraj's VVIP plane ended with the first stage itself.


"Air Traffic Services (ATS) or the responsible Rescue Coordination Centre (RCC), as appropriate, will make the Emergency Phase declaration within the time frame specified for the trigger event. As an example, loss of radio contact with an aircraft under ATS control could result in declaration of the Uncertainty Phase within 10 minutes, the Alert Phase within 20 minutes and the Distress Phase within 30 minutes of the event whereas loss of radio contact with an aircraft not under ATS control might not trigger the Uncertainty Phase declaration until 30 minutes had lapsed with Phase upgrade occurring at 30 minute intervals," said aviation website SKYbrary.


Swaraj used the brief stopover in Mauritius to meet PM Pravin Jugnauth.


The external affairs ministry had said in a series of tweets on Saturday evening: "On her way to South Africa during transit halt in Mauritius, Swaraj was warmly received by Foreign Minister of Mauritius, Seetanah Lutchmeenaraidoo… Connecting with our maritime neighbour! Swaraj called on the Prime Minister of Mauritius Pravind Kumar Jugnauth. Enhancing our bilateral relationship was the focus of the meeting."

周六晚间,外交部在一系列推文中说:“过境毛里求斯途中,她受到毛里求斯外交部长Seetanah Lutchmeenaraidoo的热情接待……加强了我们与海上邻国联系!斯瓦拉杰还拜见了毛里求斯总理普拉温德·库马尔·贾格纳特。会议重点是加强我们的双边关系。”

After these meetings, Swaraj left for South Africa. On June 6, she will visit the Phoenix settlement where Mahatma Gandhi had developed his philosophy of non-violence. On June 7, she and 300 other dignitaries will undertake a symbolic train ride from Pentrich station to Pietermaritzburg station to commemorate Mahatma Gandhi's eviction from the train on that day in 1893.

会谈之后,斯瓦拉杰前往南非。6月6日,她将到访圣雄甘地发展非暴力哲学的Phoenix settlement。6月7日,她和300名政要将乘坐具有象征意义的火车,从五里奇车站前往彼得马里茨堡车站,以纪念圣雄甘地在1893年的那一天被赶下火车。
