Title: Why chance of mid-air higher if less planes in the air?
Post by: DominicM on January 31, 2017, 11:43:45 PM
That's my experience over many years of club flying and attending shows and events. For example, last weekend, typically 5 or 6 planes in the air in this hall...and there was a mid-air when only 2 planes were in the air. Must be some logic to it!?

As 80% of the planes were on ground and 20% were in air,
This may be related to your query, but I am not sure

Hmmm. Don't think that logic works. I would expect to see at least the same number of mid-airs with more models.

Pareto doesnt apply here... It must be that when there are more flyers, people tend to be more careful, while they get careless when there are less flyers in the area.
Also, the same happens with traffic too, more accidents happen at night when there are less number of vehicles on the road.

I think you're spot on. My friends had same thought.

@dominicm,
Sir,

Two models in an enclosed space more likely to collide than several models in the same space?

Just coincidence perhaps!

Regards

You're entitled to an opinion I guess although don't understand what you're saying because you're trying to be excessively colourful in how you are saying it. Personally I thought it was an interesting observation.

You're right. No offence intended.
Have edited the post suitably.
Regards.

Maybe Heisenberg's at work here

The Uncertainty Principle. It tells us that there is a fuzziness in nature, a fundamental limit to what we can know about the behaviour of quantum particles and, therefore, the smallest scales of nature. Of these scales, the most we can hope for is to calculate probabilities for where things are and how they will behave.

The uncertainty principle is at the heart of many things that we observe but cannot explain using classical (non-quantum) physics.

So after you read that, guess what?

The Heisenberg Uncertainty Principle has nothing to do with it  :rofl: :rofl:
