The foundation has not been set for this discussion. That is, that flying more than one flight line at a contest is violation of the AMA safety rules.

Clearly there is extensive history within the sport to expect that more than one plane shall be airborn at any time. The basic design of any flying field tells you this. Otherwise we'd see only one flight station per field.

Also, while this may not be dictated by AMA guidelines specifically , most club field rules set protocol for when there are multiple planes in the air with verbiage for spotters, right of way (pilots always yield to dead-sticks, for example) and traffic patterns.

In the most extreme case there may be 4 planes in the air at any one time at an IMAC event. More often just one or two. Unless the AMA issues radical field requirements limiting all AMA sanctioned fields to a single flight station, there's no way multiple flight lines at an IMAC event is anywhere close to violating AMA safety policy.

I already addressed the differences between sport flying, with multiple planes in the air flying the SAME pattern, and IMAC sequence flying, where two planes in the air are NOT flying the same pattern and in fact my be on opposite courses or flying perpendicular to each other.

The conclusion that not flying a racetrack pattern in an IMAC event constitutes a rules violation is a flawed distortion of the safety code.

For starters, even flying an oval as if we were goldfish in a circular fish bowl doesn't remove the risk of accidental mid-air contact. Further, there are flying styles that are not even conducive to a strict one-way pattern. IMAC is just one of a few.

Unless an individual is willfully disregarding safety procedure -not using a spotter, not taking advantage of avoidance options, or intentionally flying in reckless manner - the AMA safety code does not apply. When it does apply, it would be on an individual basis.

Earle recently started a thread discussing an incident that occurred on the ground - about what can be done to better mitigate the risk. This topic is also one of risk mitigation, not AMA safety code violation. If the safety code must be interpreted as a total avoidance of risk, then we must never take our planes off the ground. In the case of the previously mentioned thread, probably shouldn't even start the engines.

I agree....at many (most) clubs there are multiple planes flying....and NOT on any particular pattern. You may have one practicing IMAC, a Warbird doing passes, loops, rolls etc, ...and a 3D pilot hulking all over the place.

Each with a spotter and all within AMA safety code.

If a spotter is critical to safe flying when multiple planes are in the air, shouldn't that be written in as a rule, either in the AMA Safety Code, or the IMAC rules? Maybe I missed it, but I didn't see it anywhere.

I gather from the reaction here that this topic is a non-issue, and that the AMA Safety Code is intended to apply to property on the ground, not other model aircraft in the air. If that is the case, then Steve's argument makes sense. No RC club could permit multiple planes in the air at once, if the AMA rule was interpreted literally.

I was out of the hobby for fifteen years, and when I came back last year I joined a local club where I am often the only one there at the field. When other pilots do show up, we follow an unwritten rule to fly one aircraft at a time. It appears I need more stick time with other planes in the air before pursuing further competition in IMAC.

Thanks to all who contributed to this discussion. May the best pilot win.

Earle, I said have an idea of what the other plane is doing.

Don't stop flying IMAC Greg, we can have another spotter with you if you like, or stop the other flight line for a moment. The next few contest in NC have been single lines the past few years because of low turnout. Hope you make it out to them. I know how you fill and the CD s will work with you till you are more comfortable. BigGrin
