Peter,

Respectfully. I disagree with Massimo. It can very easily be equidistant.  For instance, any point 10 meters above the ocean is equidistant from the center of the earth.  The plane flying a constant 1.5 meters from the ground (ocean) is always equidistant from the center of the earth.

 

None the less, I accept what you have changed it to.

Dear Paul

Following a bit of discussion with Massimo Semoli during the recent
Lugo (Italy) contest I have learned that, as Massimo puts it,: "A
plane, like the flying circle plane, cannot be equidistant from a
point (the centre of the earth). This is a geometrically incorrect
statement since a plane can be equidistant only from another plane or
from a line." From this, I believe we could safely carry on with the
suggested definitions of:

Flight hemisphere: Means a half globe shape whose base is level above
the ground.

Base: Means the base of the flight hemisphere. This lies at a height
of 1.5m above the center of the flight circle.

Level: Means at right angles to the direction aligned with the
direction of the force of gravity, as materialised with a plumb line.

Kind regards, Peter
