00:00Hello and welcome to this special broadcast on One India.
00:05Captain S.S.
00:06Panesar is there.
00:07He is the former director of flight safety for Indian Airlines and we are talking to
00:11him because of the flight that started off from Trichy in Tamil Nadu towards Sharjah
00:18had to circle over Trichy and the Tamil Nadu region for at least two and a half hours because
00:25the hydraulic failure was there.
00:28Captain Panesar, help us understand what is the hydraulic failure and what happens
00:33to the plane when it happens during takeoff.
00:38See on a Boeing 737, there are three hydraulic systems.
00:41They work for different, for landing gear, flaps and braking and all that.
00:49If there's a leak of hydraulic system, I think captain has taken a right decision to land
00:55back at Trichy and since the flight is a long flight and landing at Sharjah with a
01:01snag and all that would have been much difficult for the airline to send the staff for repairs
01:06and all that to Sharjah.
01:07No, he landed back, done a good decision.
01:10But how this leak has taken place, they have to investigate why this leak has taken place.
01:15Did the captain go check, you know, when they, before takeoff, they go around the aircraft
01:22and if there's any leak, they can observe leak also.
01:24If the pilot did not observe the leak, that means something happened after takeoff and
01:30some system and that's all the hydraulic leaked out.
01:34Sometimes the system goes out, you cannot even take the gear up.
01:37You can't take the gear up, please don't go up and you have some further emergency.
01:42It'll be very serious.
01:43Now, I appreciate this decision to land back at Trichy to save the, you know, airline functioning.
01:51They have to send the staff to Sharjah with all the mail and material.
01:55It'll take a long time and then the Sharjah investigation board have intervened.
01:59It would have delayed a number of days for the flight to be released.
02:03But since he landed back at Trichy, he's done a good job.
02:06I appreciate that.
02:07But now the only, they have to investigate how this leak took place.
02:11It is not a very common thing, but it has happened earlier also, a number of times when
02:18the hydraulic leaks take place.
02:20And the pilot has to land back immediately as per the checklist.
02:25Right.
02:26Also, sir, help us understand, the pilot decided to circle around the Indian airspace for two
02:33and a half hours.
02:35We have been told that it is because of the fuel that it was carrying since the time of
02:40takeoff.
02:41What does that mean?
02:42How does that work?
02:43Sir, I tell you, every aircraft is entitled for a particular takeoff weight, considering
02:49the airport, temperature, winds and all that.
02:52But if you take off with a maximum weight, you are not supposed to land with the maximum
02:57landing weight because landing weight, you have to reduce it.
03:00Otherwise, it will be well seated, tyre burst and so many things can happen to reduce the
03:06weight of the aircraft.
03:07So they have to dump the fuel, you know, if they can, some aircraft have the facility
03:12to dump the fuel so that the weight of the aircraft is reduced to a landing weight, maximum
03:17landing weight, and then he can land safely.
03:20But if there is a very serious emergency, he can land with a maximum landing weight
03:23also with the extra cautious, smooth landing and with a proper speed and all that.
03:29But he must have been hoping to dump the fuel or waste the fuel by flying over so that the
03:35landing weight comes within the limits and all that.
03:39For the safe landing weight, circle around to either to dump the fuel or to use the fuel.
03:45If there's no dumping facility, like big aircraft, they have a dumping facility, you
03:50can dump the fuel, whatever you like it, to bring the landing weight within the limit.
03:56If you take off with the takeoff weight, it is not the same landing weight, landing weight
04:00is much less than the takeoff weight.
04:02Absolutely.
04:03After covering that distance, the fuel is also used.
04:07Captain Pane, sir, as you rightly mentioned that the pilot did the right thing by landing
04:13in India, in Trichy itself.
04:17We have just been told that flight AI613, captain was Daniel Pellissa, a woman captain,
04:24sir.
04:25And kudos to her, as you just mentioned.
04:29And what is the kind of training or pressure handling technique that the pilots must be
04:35undergoing?
04:36She took off, she realized that the front wheel is not closing down, the hydraulic problem
04:40is there, then she had to make a lot of decisions.
04:44Yes, you see, all these emergency procedures are listed in a booklet, which is a quick
04:50reference handbook.
04:51There also on a computer also, any emergency takes place, he has to follow the checklist.
04:57And as per checklist, if his takeoff weight is more than the landing weight, he has to
05:02consume fuel or dump fuel to make the aircraft landing weight.
05:06And all these training has been given to the pilot during the simulator training, and
05:11flying training.
05:12And by definitely technical circular pilots are given enough training to land with a maximum
05:20landing weight.
05:21But if there is a greater emergency, like if an engine also fails, then he can land
05:26with a maximum landing weight, maximum takeoff weight also.
05:30And he has to land very cautiously, so the tires don't burst.
05:34So he can land with a maximum takeoff weight also.
05:37But it is better if we dump the fuel or use the fuel and land within the landing weight
05:43limit.
05:44So there's no further damage on the tires and all that by after landing.
05:47Right.
05:48Captain S. S. Bhanesar, thank you so much for talking to us and taking time out at such
05:53a short notice.
05:54We really appreciate it.
05:55And your inputs are most welcome, act as an awareness thing also for our viewers.
06:01Thank you, sir.
06:02Don't miss out.
