You seem to assume a zero length runway; and the distance from the takeoff point after 1nm, 90 deg turn, 1nm is 1.414nm not 2nm...
I'm assuming that the runway is just adequate for the aircraft (Aircraft becomes airborne at about half way down the runway), that establishing level flight/trimming at 1,000' will take a few seconds before turning downwind, and allowing a bit for the radius of the turns.
That's how it is where I fly, tight circuits at a military base.
Yes, but assuming you are flying a rectangular circuit, not the conventional oval circuit there, and that you are in the same aircraft, your circuit will be much the same as mine.
The point I'm trying to make is that, in a low powered aircraft, the minimum size of the circuit is dictated not by choice, but by the performance of the aircraft.
I'm not going to argue over thousandths of a Nautical Mile.
Here in BE, most a/d's publish the ideal circuit...
Thanks Jan. Is the patern shown varied to account for local conditions, or a standard size fits all?
