"CLEAR PROP", prompting spectator to turn around, squint and yell back "WHAT WAS THAT?"
Hadn't thort of it alerting people behind me.
Also hope that the cats that hang around at YBSS know what it means

you have missed my point, no where did I say that you dont brief them at all, I said the last thing the pax at the back want to hear is as the pilot lines up the pilot says,
"If the engine should fail on the runway, I will close the throttle, blah, blah, blah". Another way of looking at it, will to include a breifing to the PAX about engine failures before V1 and actions on etc.....pointless...
Isn't it a requirement to brief all PAX before a flight. Just tell them what they need to know, you dont hear on QF, DJ, JQ flights a detailed briefing from the Captain and F/O discussing what they will do if they had an engine failure during take-off, in a SID or on climb....
Think I have stressed my point, so I will step down now.....

PAX Comms
Took my sister flying recently. We had a partial comms failure with the intercom. I could hear her but she could not hear me unless I was transmitting. Made comms very difficult. She was anxious as she didn't fully understand what I was doing.
Made me aware of how much information I do give to my passengers within any flight.

I'm with 'PilotHTR' - and just to return to the thread......
In most aircraft, ya just can't see who may be standing behind ya....You know...walked up to near the back of your aircraft while you were adjusting seat belts, 'thingies' etc....
Therefore, in the interest of 'safety and situation awareness' - for the bloke who may be behind ya - and anyone even NEAR ya - shout it L O U D &
C L E A R!! and with 'that' FLOURISH!!
Always dun it - always will - no matter if to some it does seem a 'silly thing' to do.....

what you doing now? I thought you were blasting big hours up north in the Kimberley or somewhere. Have you got rid of those stupid "remove before flight" tags on your headset bag?
but what about (in singles) below the nose?
didnt an instructor get chopped relatively recently at Point Cook when the engine was started?

Finally, the student was left in the aircraft while the instructor attempted to start by hand and the student had no instruction in hand swinging. There was a cock-up over mag switch positions and the prop came to life unexpectedly. The instructor was fortunate not to lose his life. The responsibility for his lack of training starts right from the top as with most accidents in aviation.
The words "CLEAR PROP" may not mean much to an inexperienced aviation person who just happens to be in the danger area. Far better to use concise clear English of "STAND CLEAR" in a loud voice.
The old adage of "If a person gets away with anything long enough, the perceived risk diminishes considerably." is ever so true. Been there-done that. Just remember that if you really cannot be bothered to shout "STAND CLEAR."

Props can hurt you at the most unexpected times. The Lancaster bomber was a tail-dragger (conventional undercarriage) with four Rolls Royce Merlin engines. Engineers working on the engines used a ladder to climb on to the wings to get to the engines which were 15-20 feet off the ground.
One engineer who fancied himself as a budding Tarzan used to jump off the engine and with both hands on the propeller, allow his weight to slowly rotate the propeller against the engine compression and lowered himself to reach the ground quite gently.
On one occasion he did his act but unfortunately forgot that he had removed all the spark plugs on the engine he was working on. He leapt from the top of the engine, grabbed the nearest prop blade and of course crashed to the ground when the prop turned freely with no compression. He broke a leg and never did it again...

common sense
...................99.9% of aviation is common sense, (the other .01 % is left to "murphies law" !) seeing as we can see quite well out of yr average light A/C (esspecially considering where the offending subject matter is placed, excepting of course the C336/7) the mentioning of "clear prop" should always be done if there is doubt as to whether there is a potential for anyone being in close proximity to yr plane.
....................like others have said amongst these pages...........it's also about airmanship, something that's being let slip more & more these days sadly

For those budding Kimberley pilots, if you dont remember/bother to say "Clear prop" your 'more regular' passengers will certainly remind you....
...disco
Eh pahlot, you porgot to say cleerprop!
or "Stand Clear"
[QUOTE=glastar;2934694]
I switch on my beacon, visually clear the nose area,make the call, wait a couple of seconds then, still watching the prop, turn the key.
After 50 years in the buisness I still observe the basics.
/QUOTE]
Ditto. However, I YELL "Stand Clear" as quite a few times when I've used the term "Clear Prop" bystanders just look dumbfounded.
Therefore years ago I changed to the "Stand Clear" as I find it encourages a more inquisitive response. And yes, the couple of seconds pause before activating the starter is wise.

Who said flying is safe?
Anyone who says that flying is safe should be shot. The reason we run through standard procedures and have regular checks is to make is safer! If flying was safe, then we would just turn the key and go.
As a bugsmasher on a public aerodrome, it only takes a couple of seconds for an unsuspecting ped to walk into harms way. I would much rather have someone look at me funny than clean up a mess.
'Tis also good practice to remove microphone away from mouth!
Here is a good website with a thorough pax brief explaining the risks of flying http://www.secureav.com/
ECT?

Especially at Ardmore (New Zealands Busiest Aerodrome). there is so many aircraft movements (including Helo's in the Tlof) that one can never be too cautious. Safety is paramount. And anyone who has beliefs otherwise shouldn't be allowed to hold a licence!

Well when I start a plane, I usually make sure it's in a suitable place to start it ie: not over loose gravel, into wind etc. What I usually do when I'm starting the engine is I look back and forth, say to myself 'clear front and behind' just before turning the key.
Then after that I open the window, take a deep breath and yell 'clear prop'. Then, after an equally deep breath, I yell 'stand clear' for the other people who might not understand my first PA. Then I take a deep breath and yell:
stand clair (french)
Standplatz frei (german)
basamento libero (italian)
carrinho desobstruído (portugese)
and
στάση σαφής (greek)
Just to make sure.
Then
I unbuckle myself from the plane and jump out and have a look underneath to make sure there aren't any deros sleeping under the engines (this is an ideal time to take an extra, paranoid fuel drain by the way) and jump back in.
Of course, if you follow my lead and want to do your runups in the same position you'd better make it snappy, lest the wind direction change during the process.
