riff-raff

Your comments are well observed and in the context of recent history they sketch out a way forward. However, before we had the 30 minute run-dry qualification test there was....... let me think...

Well that's a small step for man and great leap forward for mankind..... at least for Brazilian mankind. I hope the many other areas worthy of attention have also been addressed but I will be very...

Offshore ops......

It was ever so. The rot set it in the '70s when the UK government accepted that quasi-military standards of operations were acceptable in pursuit of the national interest. They are not my words...

Brazil

If Petrobras were focussed on safety and thought C/As were a good thing then they would feature on all types but they don't. Conclusion - Petrobras want to maximise payload and therefore have to...

Rear seat crew!!

This argument is reminiscent of the one that followed the demise of the Flight Engineer and will suffer the same fate. Alas the genie is out of the bottle and despite this one incident I doubt that...

What of the future

There is a general misconception in the helicopter manufacturing industry that their customers are the 'operators' which is unfortunate because many of us wish they recognised that in a major part of...

Agree entirely save for warm room and cosy chair I would say that the perspective frequently suggests they are downwind in the circuit on a lovely summer's day. They also appear never to have read...

RFM with questionable contents

I must agree with 212man. The key is in company SOPs. The RFM is a document based on the basic aircraft and does not integrate these basic procedures with those variations required by the...

Tail Rotor Malfunctions and training in the sim

I agree with Jim et al, tail rotor drive shaft failure is available as a malfunction in our sim but I always precede its use with a little speech that highlights the dangers of any 'lessons learnt'...

Regret I can't agree. If any of the three critical gearboxes on the 234 seize then you exit stage left in a hundred bits but if the tail or intermediate gearboxes fail on a single rotor...

I once gave a presentation at which I explained why we had chosen the MD902 for the London HEMS role. Afterwards the EC(F) rep cornered me and asked why I thought the NOTAR a better bet than...

the 234 story

SAS - There was a lot of talk at the time about the CAA being put under pressure by both the oil company and the operator as well as the manufacturer. I remember being at a 234...

Thanks Jim, the last paragraph is prophetic (re the sync shafts in the 234) and my bleat was just a regurgitation of a long-standing gripe about the introduction into service of that...

I take your point vis a vis the established emergency protocols and would not seek to replace them but merely to give them a context. As experience with a new type grows we know that a greater...

You have hit the nail on the head. If we ONLY cover text book emergencies during sim training we run the risk of creating a generation incapable of thinking outside the box.

Thank God for LOFT...

Helicopter design - S92a

Looks like the designer(s) of the MGB and ancilliaries will not be getting an Oscar any day soon. It's interesting that the physical integrity of the AC gens should be dependent on the MGB oil...

Many thanks for adding that detail. Fascinating as it may be the point I was making is that the test seeks to second guess the failure mode which, as we can see does not entertain any other internal...

Am I speaking a different kind of English ...or what.....?

I say again. Inadvertant inflation of the 139 floats IN FLIGHT has never happened. CFIT (into water) has. This is not a question of absolutes but a question of probabilities and as far as I can...
