Senior Pilot 10th Jul 2010 06:58

00,

The hover trim has been around for many a moon: 10% cyclic authority for the winch operator to move around when in auto hover. Originally fitted to the Sea King HAS1, before which (as sycamore mentions) all fine trim was at the pilot's whim.

RODF3, 2 metres seems a very coarse measurement? ISTR yards for horizontal movement, feet for vertical, but bananas and apples as we all well knew! All according to CPO (Aircrewman) Mooney: he of the broad Oirish accent, and the rather attractive daughter ;)

you can't say right 2 followed by left 6
Trying to recover a training drum that had been beached on a coral reef with a grapple just as a wave came along: That was exactly the 'con'! :ok: ..followed by a few expletives that are not found in the VM Handbook.

The SAR unit is variable in length because of the different levels of precision required depending on the type of rescue. Fwd 1 could be as little as 6 inches if you have stopped just short of a cliff-sticker and the winchman needs to be pressed onto the cliff face.

Tiger Mate - if we are inadvertantly descending, the winch op will say 'you are sinking' - maybe that's why the Navy don't like it:)

Fwd 1 back 6 is pretty standard patter for surf drums/wets!

What is the RN/RAF deffinition of the winch-op call of "steady"?

Does it mean hold position and height or just position.

I believe it is used by both in the same sense. To stop all lateral/forward & aft movement and hold position.

'Height is Good' serves the same purpose for vertical movement, ie hold the height and cancel any descent/climb.


For example does "steday & down 10" make sense?

Steady, Down 10 makes sense. 'and' is ommitted as it is superfluous.

TV - "Steady" means that you have arrived at where the W/Op wants you to be:ok: It will be repeated if the position remains good, otherwise the 'patter' will indicate what movement is needed. Many years ago (Whirly 10) we had a crewman stude who had an intermittent stutter generated by sybillants. His patter would go "Forward 5,4,3,2,1 Ssssssssss ... Back 6" He did not pass the course:(
Sycamore - Ah, yes, Master (Sig) Bates - (thought it was Roy??) He, together with Ricky Windon and Gene Batten got me operational in '64. First wets in a leaky immersion suit in April left me numb and near incapable of movement. They dragged me into the (very) hot shower and once I was mobile again stuffed a LARGE glass of 'pusser's' rum down me - almost worth the agony for that:ok:
Happy, happy days.

I think that you will find that SAR and SH units are now supposed to be the same size after harmonisation a few years ago.
Agreed, but having done both recently, they ain't.

AHT was also fitted to some Sikorsky S-76s.

SAR everywhere,

Having just got my computer back I'm able to say thanks to you all, & particularly those who replied to me ( as a yachtie ).

To be pefectly honest it's a matter of horror & excitement if a SAR helo' approaches in case one gets picked on for practice !

I think nowadays it would be excitement for me, but although we yachties do get some info, and I'm delighted to fly, know about static shocks, hearing anything even with internal and cockpit speakers is impossible once the aircraft is near.

I know on approach there's often a request to steer a certain course, but even catching that can be a snag either due to aircraft noise or nagging girlfriend etc !

Double Zero - the course asked for will almost always be a close hauled port tack for sailing vessels - that is because it allows the aircraft to be pointed into wind approximately 40 degrees off the boat heading, giving the pilot some hover references and an escape route away from the boat for both aircraft and winchman in the event of an engine failure.

the winchman - bloke still aboard
Never mind eh? :ugh:

sycamore 12th Jul 2010 21:53

C-Jack, you are correct,M/Sig Roy Bates...great time we had at Valley..in the summertime..

Double Zero 13th Jul 2010 11:41

Torque O D,

Re. 'winchman, the bloke still aboard' Yes I could have phrased it better as controller, but I think you get the idea...

BTW I'm sure most SAR people must be trained on this ( I've photographed from most things, fast jets to balloons & Jet Rangers but not SAR ) - sailing boats work by 'spilling wind', ie as they heel over the wind goes over the top of the sails, relieving centre of lateral effort pressure; a helo' works like a katabatic wind ( rotoring down not along ) and can blow a boat down - unless it's a dinghy it's not disastrous just awkward.

I've been sailing & instructing for 40 years - inc being a chief instructor for BAe, I would guess the instinctive reaction to that would be ' why didn't I drown them ' ?!

Cornish Jack 13th Jul 2010 17:39

Sycamore - slightly long-winded thread creep but your description of Whirly 10 'computer out' brought back memories of a Master Pilot returning to helos after original Whirly 4 ops. (Whirlwind Mk4 was piston engined and required a deal of co-ordination of twist-grip throttle and collective to maintain the narrow band of correct rotor revs)
On the 10 'normal' flying had 'computer' control to allow automatic throttle compensation for collective movement. If you selected 'computer out' you reverted to twist-grip co-ordination. Said Master Pilot was never the most accurate in the hover when computer-in but the moment he went computer-out, it all calmed down and the rotor revs never varied!!

So what is a dope on a rope?

All this SARboy talk is getting me all dicomknockerated - they told me at SARTU it was all black magic and not to be messed with by simple SH types.......don't you just love em?

charliegolf 15th Jul 2010 13:54

I went for 2 weeks, long before computers. Do think they've moved that line onto a PowerPoint by now?:ok:

Just remember the magic word, "correction"!!

I always thought the magic word was 'abracadabra'
