If you'd stop wearing all that polyester and nylon.........;)

I've never even heard of this before, let alone had it happen.
I did use one of those military type wrist straps when I first heard about this, then I came round to the 'what's the chance of that happening' stage. :ouch:

Depending on fit/setup, next time you land, pause with the collective fully down and note transponder and/or TCAS indications. They probably still say ALT and Normal/UNR/ABV/LW depending on type. Without doing anything, those indications will remain. Now lock the collective and within around 5 secs the indications will change to GND, STBY and/or something else.

You can sit for hours without making the contact waiting for the status to change, just incase you think its some other system at play.

Watch straps, contacting the locking nipple at the top of the collective and earthing through the body, as I said, certainly wakes you up after the umpteenth orbit of a dimly lit church in the middle of nowhere at sparrows fart!

Just tried to video the spark (so much for the need for sparkproof torches etc) but it doesn't show up too well, despite being able to see it with the mark 1 quite nicely.

However I did discover something not normally noticed, in that when you connect/disconnect the nipple/locking device there is some 'wiggly amp clicky business' going on around the base of the collective area. (awaiting correct technical terminology) :8

I have never suffered from the spark but ours is a T2 from 2001 isn't yours a P2+ or am I mistaken, I think over the life of the 135 production there are three systems employed to tell the boxes when the aircraft is on the ground.

Keep your watch, wear gloves :ugh:
Does that mean we should wear our watches on top of our gloves/flying suits?
We could pretend to be astronauts or deep sea divers ;)


If you release the pitch then you can feel the voltage by your arm: just fly a little while and then there is enough power between the "black" parts and the silver shining PIN.
If the pin is insulated, then there shouldn't be any other circuitry going on...should there?

fully aware of the technical side, which you may have been able to pick up in my post,
And enough of the head-banging !

SS,

Why not combine your glove and watch...?

White gloves !!!!!

Brilliant Stuff 10th Jul 2011 08:35

Glad to hear I am not the only one re: White Gloves.

SS + BS,

Apologies for the sartorial faux pas.

The suggestion was merely in response to the concern about having to adopt a watch-over-glove solution and not an endorsement of any particular colour!

Man, you weren't kiddin' about the zap. I normally fly in suit and gloves, so I had to experiment. Placing my watch on the lock pin, touching the ldg light switch caused some tingling on the skin... And after a second or so, the zap, which was strong enough to contract my hand .

That's it then, I've got to go have a play this evening :)

I struggle to see where the charge is coming from, is there a dirty great big capacitor in the line or something?

Cheers

Saw it being ground run the other day at EDPR while picking up one a few numbers prior to it.

Was also told that at that time up to #1038 has been signed up.

Good machine obviously!

EC-135 - New landing gear - Floats compatible?
 
The EC135 has now a third option for a landing gear with a height of 0,5m. Can you tell me if this landing gear is compatible with the emergency floats. Thanks

zami - The Apical floats are compatible. Fairly sure the same goes for the Aerazur system, but I'll confirm.

EC135 YAW SAS?
 
Our mechanic is at wits end on an "intermittant" YAW SAS issue. With increasing frequency the system is kicking off while in cruise flight (more frequently in gusty winds) however it is kicking off in all phases of flight.

The aircraft will yaw 5-10 degrees and then the system will kick off line.

He has replaced all major components including the wire harness in the tailboom.

Any suggestions to trouble shooting?

ACFT S/N is 0015 and has 6800 hours total time on the airframe.

RotaryWingB2 6th Oct 2011 17:52

Going to need a bit more info than that.

Parts replaced? (Yaw SEMA, FOG's?)

Does it pass a BIT check on the ground, when it fails what are the indications?
