Hari Nair Sir,
Deeply appreciate your contribution to this thread and forum. Since i have an inherent interest in all things related to flight safety, I have a question regarding the ALH. What exactly happened, and what may have been the cause during the Sarang practice session of the last Aero- India that resulted in a fatality? And were there similarities in flight profile to the Ecuador incident? Was it engine related, transmission or human factor? Thanks very much.
Thanks, gnair. I presume with your stated interest in flight safety, you obviously know much more than what you are letting on. So go on, why don't you tell us what you think of the ALH. And on that count may I also request for an impartial insight into the flight safety stats of contemporary helicopter types during their development and in-service usage (military & civil). So go on sir, the 'transmit' button is all yours!
Hari Nair Sir, Shiv and others, thanks for the response. Seriously, i don't know anything more than what i have read in the local press at that time and since they sounded vague, i thought i'll try and get the inside perspective. And i haven't heard anything adverse about the design or manufacture of the ALH either from industry circles, barring the tail rotor issue that has since been rectified. On the contrary, i still hear great stuff about the Tarang performance in Singapore a few years. That must have been the best PR exercise by the IAF for all of the ASEAN region.
Coming to the point, accident investigation reports are always sensitive, especially when there is a situation, where we've lost one of our own.
My own speculative question is 1) Was It an unintended induced stall due to lack of power/speed at a certain angle of attack or
2) Was it Lack of clearance/height for recovery, and unexpected delay in relay of engine power to transmission/rotors leading to a CFIT during a hover.
Thanks.
Gnair,
I don’t believe you have either responded to my request or whether the gist of my message has even registered! Since we are in a serious & professional forum and need to rule out sciolists with perhaps ulterior motives from hijacking the thread, I’ll repeat my earlier reply:
“So go on, why don't you tell us what you think of the ALH.
And on that count may I also request for an impartial insight into the flight safety stats of contemporary helicopter types during their development and in-service usage (military & civil).”
So if we need to continue this discussion any further, please address my request in full.
And on that count may I point out sir, that its SARANG and not 'Tarang' or whatever you had typed. If in doubt, we can always take the trouble to 'Google', I suppose!!
For Hari Nair:
Gnair: With all due respect Sir, yes I meant Sarang and not Tarang. That was shoddy typing.
Since we are in a serious & professional forum and need to rule out sciolists with perhaps ulterior motives from hijacking the thread…………
Gnair: I’ve been associated with this forum for about ten years now, one way or the other and hijacking a thread isn’t a part of my track record. I usually recommend folks interested in various subjects of interest to visit this forum. Personally I use BR, as a reference source.
need to rule out sciolists…..
Gnair: That is a big word sir. The criteria I used, to ask you this: “ What exactly happened, and what may have been the cause during the Sarang practice session of the last Aero- India that resulted in a fatality? And were there similarities in flight profile to the Ecuador incident?”
….Was because it was established that you were the subject matter expert in the loop, and I was the layperson on the outside. It was for no other intention or motive.
If there were sensitivities in the questioning, then a polite decline would have been the norm.
Re-questioning a genuine, legitimate question is usually a mark of defensiveness. There is no reason for that. This is friendly territory. You, I and everybody else are on the same side and no one is taking pot shots at anybody.
…..and coming to your counter-question, irrespective of the relevance or lack there off to what I asked you:
“So go on, why don't you tell us what you think of the ALH.
And on that count may I also request for an impartial insight into the flight safety stats of contemporary helicopter types during their development and in-service usage (military & civil).”
Gnair: I think the ALH is a great helicopter, without a doubt what so ever, and have followed it from the drawing-board days in collaboration with MBB. First flight in the early 90’s with the LHTEC 800, then came the embargo/sanctions and switch to
TM-333, then the switch to digital avionics, incorporation of vibration reduction systems, weaponization and now with the Shakti. Besides it’s got good lineage from the BO-105 and the BK-117, two great MBB/Kawasaki products. So the design is fundamentally strong. That’s my brief laypersons take on it.
…….may I also request for an impartial insight into the flight safety stats of contemporary helicopter types during their development and in-service usage .”
Gnair: I am not associated with Bell, Augusta or Euro Copter and as you can understand, I will not be in possession of up to date data that is relevant to your question. I am sure you knew that, before you asked me the question!
Your request is bordering on proprietary data. I may be able to look up the annual Incident Reports for rotary craft from Flight International or AW&ST at best.
Let me conclude, that the answers to my questions will not be forthcoming from you. Therefore ‘I choose to withdraw my question to you Sir’ .This discussion could have been taken in better light, but then I guess not. One cannot be trained in emotional intelligence. It usually comes with layers of life experience.
The first two prototypes are expected to have the "default colour Black" as you put it and the other helicopters that follow are expected to be in standard IAF Grey. The IAF Grey is actually quite difficult to spot against most terrain and sky conditions.
Does Tiger on LCH has some specific meaning? also i was just thinking how will Tiger look on grey color scheme...
