Hawker vs. Glider Midair - with photo!

("Stefan" wrote)
It's a pretty bad book. You calculated what it takes that one particular
glider hits one particular jet. But this isn't of any interest. The
relevant question is what it takes that in a sky full of gliders and other
aircraft, there will be a collision between any two of them.


....a collision possibility that will pass (in the case of the Hawker) in two
tenths of a second, or less.

One tenth to enter (and fill) the box, one tenth to exit (or clear) the box.

You want the powered aircraft to use it also?
And you know that FLARM actually works at those speeds?

It's true that it hasn't been tested much in practice, but FLARM is
definitely designed to work in powered aircraft as well. Actually, it
is already installed in many SEP aircraft in Europe, especially in
those susceptible to operate in the vicinity of glider crowded areas.

250kts at a range of 2-3 km still gives you 15s of reaction time.

Of course, neither FLARM nor any anti-collision system is a replacement
for SEE AND AVOID which should be the highest priority of good
airmanship.
