"Clear Prop!"
This one came to me having read the thread on strobes.....
What is the general concensus on shouting "clear prop" a few seconds before start up? I was always taught to give this a good holler out the storm window and wait a few seconds before hitting the start button (to allow any small children, sleeping vagrants etc to get out of the way before the prop starts moving).
I've had my PPL for around 7 years now and I can honestly say, on every start-up, I have always followed this routine. Thing is, at most airfields I fly from, I hardly ever seem to hear anyone else do the same.
Am I being a wally sticking to this or am I right in thinking there's a lack of airmanship on this point?
Please discuss........

Would tend to agree - I always do it but never hear it done away from base. On a flight with an instructor in the US he actually laughed at me and ...

I've been doing that for the past 22+ years and I wouldn't care a fig if someone thought me funny for doing it. I do it loudly enough to get a startled look from someone in the middle distance - achieves its purpose - great!
Yes, I'd say that there's a slight lacking of airmanship in someone who doesn't do everything they can to ensure no-one's going to get hurt when they start the engine.
As to the US not understanding it; I bought a tee shirt last time I was at Kermit Week's Fantasy of Flight. It depicts a mechanic astride a Wright Cyclone with an aghast expression on his face as the words 'clear prop!' explode in a bubble adjacent. I'd say that it's well understood in proper aviation places.
Of course at work, no-one would be heard - can you imagine Nigel winding open the DV window on a 777 to announce his intentions? - so we rely on anti-coll beacons being switched on.
Cheers,

Oscar,
I agree, the shout of "clear prop" is becoming a bit rare - shame, I think it's very important. I'm a club CFI and I insist my pilots and students do it. You keep shouting!!

Clear Prop!!
I yell this over here in France, and I dont care if Im looked at either, thats the point of it. Seems to cross the language barrier because Ive heard it yelled at les Aeroclubs Francaise too -though maybe by Brits
What is the French for "Clear Prop!!" anyway, 'Attention/Guarder l'helice'? I dont know and have never thought to ask, I just rely on the yell bit to get people looking the right way prior to start.
Regards, SD..

Most people I know all shout it but they vary in how they shout. Some say "CLEAR PROP" really loud, some say it a bit quieter and one or two say it like this "Cleeeeeeeeeeeeeeeeaaaaaar PROP" or "CLear PROOOOOOOOOOOOOOP" Some just shout out "PROP" 
How do you do yours?

I yell almost all of the time, even here at home when I know I'm on my own! The only time I don't yell is if I have a chum standing near my aeroplane and then I politely ask him to confirm that it is clear.

It's a bit like pre-takeoff safety briefs (which I think many pilots neglect even more), or downwind checks (which aren't technically all that necessary in some aeroplanes without flaps, mixture control or retractable gear if QFE was set already and you've checked fuel and wind on approach). Very often it isn't necessary, but if you are in the habit of doing it every time, then you won't forget when it's important.
So, I do a verbal take-off safety brief every time, even when flying on my own. I call "clear prop" every time, and most of the time I remember to do downwind checks, even in a simple microlight.
How do I do mine BRL?, Loudly!

As for the French for "clear prop", I don't think it makes any difference what you shout, so long as you shout something. Let's face it, most non-aviation people wouldn't know what "clear prop" meant anyway - and they are the ones most at risk, in my experience. But hearing something being shouted will at least get their attention.

Ah! a topic recently brought home to me!
Having been a firm member of the "shout it loudly before starting" club for many a year I was recently taken aback when, upon starting up a 152 for a flight with an instructor friend, he said "please don't shout that! its the most dangerous thing you can do"
After calmly thinking about what he has said for a few seconds I asked him to clarify.
Apparently he had once also been a member of the shout loudly club until a rather unfortunate incident.
He was flying in South Africa in a bipe taildragger with very poor forward vision when on the ground (cant remember the type). He shouted "Clear Prop" prior to starting and a fellow brit, who was nearby but could only just hear my friend due to engine noise elsewhere, wandered over to see what all the noise was!
The next thing my mate knew about it a head was popping over the cowling with a friendly "Alright over here?" just as the prop began to turn.
Luckily both of them had fast reacions, the guy lept to the floor and back before any damage could be done and the pilot managed to shut it down before the prop got really swinging.
From that moment on he has never shouted it prior to turning the prop for fear of a repeat, but possibly more nasty, event.
Which I can sort of see the sense in really, do you not agree?

jezbowman, I have flown with several experienced American pilots, and they always shouted "clear prop!"; so I think your experience reflects incompetence on the part of the individual instructor (sic!), rather than a difference between British and American practices.
I was certainly taught to call "clear prop?!" before starting, and always do so. In the Harvards, we call this out before energizing, and call "contact!" just before engaging. The noise of the inertial starter winding up should provide some warning to bystanders; but I certainly wouldn't count on it.
As pointed out here, if there are any ground crew or other pilots standing near the aircraft, they should visually check that the propeller area is clear and respond "clear", usually with a thumbs up.

I do believe you were told it, but I don't believe it happened. If you heard someone shout something from an aircraft, would you walk over, through the prop arc, to find out what was being said?
Nor would anyone else.
And why didn't the chap start immediately after saying it? Why wait 10 seconds for someone to walk into danger?
I shout loudly, even when I know for certain that I am the only person at my strip. I will continue to do so, as well. For me, its just part of going flying.

Odd one,
Nigel and his ilk plus the RAF do not need to shout as they have a groundcrew man standing in front of him who is either on an external i/c lead or is in communication through standard visual signals. The pilot will not turn an engine unless given clearance so to do by the groundcrew.

Yes I too shout 'clear prop', tis common sense for the benefit of safety, just like leaving those blessed strobes off.
Nice to see common sense still applies. Lets use this and the strobes thread to shame a few non-thinkers to engage brain before committing aviation.
Safe and happy flying!

Plenty of basis poor airmanship (or groundsmanship?) diplayed at most airfields.
A recent example is when an instructor (I assume) started a Decathlon with it's tail pointed into the hangar here at Goodwood. We were having our Falconar inspected at the time and going through the paperwork, layed out on the wing. You guessed it! Paper everywhere and us having to hold it all down.
Surely that's basic stuff? I was certainly always told not to start up without checking what's going to get blown in the slipstream, and certainly not tail into the hangar!
Then there are the little things like leaving the straps neatly in the cockpit, turning the prop (carefully) to a position it's less likely to cause problems for others in the hangar, wiping the fresh bugs off the leading edge ect ect ... All pretty small in their own right, but they add up to good aviation practice, which is surely what we should all strive for?

Nearly always been taught to shout it, but recently have adopted "stand clear" as oppoesd to clear prop.
Just makes it a bit clearer if there's no aviation folk around.
Either that or just "CLEAR".

I wonder how many accidents have been recorded which could have been avoided had the pilot shouted 'clear prop'? I'm guessing not many but let's have some hard statistics here.
I accept that I could not see someone on hands & knees under the nose of a PA28 but perhaps an unexpected engine start would stop them doing it again. I go along with Darwin and the theory of evolution.
