Status: offline 		The AMA separation distance numbers might be appropriate minimums for the average club field. For jets, wouldn't it be better to increase those safety zones? I would most certainly increase them at jet meet sites where there is more concentrated activity. There are also spectators that might have no clue how heavy and fast the average jet model is.
Such spectators would be considered the unsuspecting puplic.

No necessarily. Remember Turbine Jets are required to have working rudders, have brakes and a sign off of pilot ability. Jets, on the ground, will generally cause LESS damage to soft tissue than a spinning prop.

At Jet events, the spectators are much farther away than I think most people realize. Anyone in the pits is no longer a spectator. They should be a pilot (flying or not), part of a crew helping the pilot or ave signed off to understanding the risk (photographers, etc). Most every event I've been to does not allow spectators in the pits

You're right about ground operations. The safety zones are probably adequate. Most pilots and aircraft are up to the task. I guess I'm more concerned about in-flight hazards. At some meets I've been to the flight paths are very close to the pits and therefore very close to the spectator line.
In addition, at more than one meet I've seen a mix of crew, pilots, and family members/friends all mingling in the pits too. I agree most meets don't allow spectators in the pits, but they are there anyway. The issue may not really be safety zones, but rather people control or lack of.

I hardly think Moms or Dads with toddlers, baby carriages, 12 year olds carrying balloons, cotton candy tripping over model jets, would qualify as crew. Often I see them with pit passes too. They are unsuspecting (and uncontrolled) spectators. I don't go to more than 3 or 4 meets per year, but I have seen this scenario at the majority of those meets. How often do we see the spectator line spread out along the length of the runway? Almost always Mom and Pop set up the lawn chairs closer and closer to the edge of the runway the further away from the show center they get. Hmmm...right where the jet is at a critical point in the approach or takeoff too.

For the record, I've seen this at prop events as well.
The CD has a challange. Keeping it fun for everyone, giving folks their money's worth, and safety. That's why they are paid the big bucks

If one was to overhaul the safety program at an RC club that has several jets, pylon races, etc - what are, lets say, the top three things that have been done in the last 5 years that have been deemed as an improvement to safety that also allow flexibility in flight operations?

Or - are we still doing things the same way for the most part?

I assume some of the larger clubs that host large events are probably more progressive in implementing new ideas, etc. However, necessity is the mother of invention as we say, so I'm sure good ideas exist everywhere regardless of size based on individual circumstances.

Status: online 		Well, heres another incident which proves that safety awareness and close inspection of our jets is vital. In preparation for this weekends meeting I have spent today meticulously checking my Mig 29. Everything checked out fine , flight controls , engine failsafe settings, and hydraulics for leaks etc. Usual stuff. Fuel system undisturbed sincle last time but just an engine run to check them out as the engines themselves had been out.

No 2 engine, fine. No 1 engine, left, slow to ramp and would not reach full rpm. Shortly afterwards fuel seen dripping from cowl.
Investigation revealed that the pressure line from pump to cutoff valve was not over even the first barb and was quite loose. Nothing has been touched since installation so it must always have been this way and the engines have been run many times without any problem. However the fuel line (Festo) has aged and lost what grip it had, result could have been a serious fire. Yes, it was my fault that the fuel line was not over the barbs but perhaps this can be a "heads up" for anyone who uses unbarbed fittings, such as some tube joiners like 3-4mm. Festo tubing WILL age over time and can lose its grip so if your fuel lines are of some age you may care to give them a close inspection, particularly if you used any unbarbed fittings in the pressure lines. Might save you a fire.

Regards, David Gladwin.

Status: offline 		Only points out the obvious, David......that shut-offs/any filters/Tees, etc., ought only to be on the pump feed side...w/ a straight shot/no breaks in the pressure line. I.e., pump-to-engine as directly as possible.

We use all manner of Festos...never had a problem w/ this configuration......and any possible air bubble introduced, due to a bad connection, is usually obvious before flight upon inspection (though I've never had one)....and HAS to be better than the situation you potentially had on your hands !

The pilot landed fairly quick after that, I sure hope he was ordered to and sent packing.
The bump that turned the plane toward the pits was in the first few feet of the take off roll and it could have easily been aborted, taxi around and tried again.
There was absolutely no reason to continue the takeoff through the pits/ready area.

i second that, did you notice where the pilot was standing?
