Propeller Safety

As a space cadet of 9 years I remember that almost all the bogs within RAF facilities seem to have a flight safety poster or 2 about the danger of props, often depicting limbs being torn off, so I assume that it is a big deal.

I guess those who run the PR machine for the ACO don't understand the dangers, having come across this picture at www.aircadets.org



How do I grass them up?

I thought they were only dangerous if moved casually, not just standing next to them?

It's a bad example to set - I was always taught never to be within the arc of the propellor and also to treat propellers as live at all times.

I was always taught that a prop would "fail safe" ... ie, it would fail safely from the pilots persepective, live and keep spinning, not stop!

But as for grassing up the ACO ... I wouldn't have thought it worth it!

I always teach my lot to assume that the propeller is live and desparate to turn them into 'chopped ham and pork'. They are, therefore (I hope. Fingers crossed etc), less likely to walk into a rotating one! However, has the battery been disconnected on this ac etc...?

Seem to remember in the long distant past, a late passenger somehow getting through a closed gate to get his flight at Aberdeen, (748 Dan Air possibly) and meeting his maker unexpectedly, with the assistance of a Rolls Royce Dart.

I suppose the ironic thing, is that if it were indeed Aberdeen, then he would have been diced at Dyce.

Props KILL ----end of story. Any prop should always be regarded as "live" therefore. Had the message, er, "taught" to me many years ago at Halton ( hence the reason for including above quote re chopped ham etc ) in a short and succinct "lecture" with liberal use of the "f", "c" "b" and "t" words to describe said C/T's perception of apprentice's and props. Worked though.

Same as the "take one frog--alive" "take one pot of LOX" and, plop, shatter, tinkle. Neither approach would, I assume, be condoned in the PC Air Force of today, but they both worked in getting the safety message across which is the key point.

Take one space cadet, take one spinning prop and plop, i for one think this would be a lively demonstration on prop safety, in fact i will volunteer to throw the spacey.

So it would be true to say that the "late passenger" became a "late passenger" after being diced at Dyce?

From an extremely young age I had it drilled into me by my father (a former RAF and airline pilot of considerable experience) that every propellor should be treated as if it was turning or about to turn at any time. In fact the severity of his warnings struck the fear of God into me and have stayed with me to this day, so I cringe when I see pictures like this or people pulling light aircraft by the prop blades.

Props kill people all the time, mostly walking into turning prop arcs but static props should also be treated with tremedous respect. I am fairly certain that people have had fingers, limbs and lives removed by props turning unexpectedly due to switch pigz and electrical faults.

If, as I was taught, you NEVER put any part of your body through a prop arc you can't go far wrong. When checking the blades on the walkaround you do so carefully, preferably visually and you certainly don't curl your fingers around the leading or trailing edges (just as when swinging a prop). (The only exception would be helicopter rotor systems where the greater inertia means they cannot move suddenly. Even so, rotating tail rotors kill regularly).

The picture is an appalling example and I am amazed that some people here seem to consider common sense safety practices and general respect for the aircraft to be geeky or unnecessary.

A lot of you are soooooo BORING !

Some of my most favourite photos are of WAAFs on wings, stewardess in engine intakes - horizontal, sitting, standing and a trio together (RB 211).
I've got dozens in open doorways, standing on wheels and hanging on hoists.

By being sensible and understanding and explaining the risks, we never as much as broke a carefully manicured finger-nail or laddered a stocking ..................but everyone involved now have some fantastic and unforgetable pictures AND we all had a good time producing them - and please don't say we were lucky.........ref. 1st sentence of this para.

If the critical comments represent a measurable percentage of service attitudes.............Thank Heavens I'm out of it, I don't think I would last very long in such a service.

There's one every few months, unable or unwilling to read what's at the front of the forum.


FWIW you should always treat props as live. Turbo props too can spin unexpectedly and if you're lucky you'll get away with it. If not don't come running to me!

Propeller safety ... Getting the message across

A few years back I saw a flight safety poster depicting a Tucano propeller shredding a poor unfortunate who had come into contact with it, this cartoon depicted a red mist and body parts going in all directions and was the most effective poster I have ever seen on the subject.

May be its time to re-issue this poster? It sends a stronger message than all the good advice that is writen above.

Hmm. Who's inventory are these aircraft on? Certainly not the ACOs.
