Not if everyone is following them, which is the whole point.
Having "everyone" is following local noise abatement procedures does not
make them safe.

Non sequitur.

Sequitur.


Having one yahoo not following the same procedure as everyone else
no matter where the procedure comes from is not safe.

That's not only not true, it is laughable. Not everyone has to depart
right downwind, and having somebody depart straight out or left
crosswind is not unsafe =just= because everyone else is going out right
downwind.

The standard North departure for CCB, for example, is downwind
and turn North over the approach end. If you depart upwind and turn
North, which is a "standard" AIM departure, you are flying directly
into arriving traffic from the North which enters the patten on the
crosswind.

It could be unsafe because there is a mountain in the way. It could be
unsafe because it crosses another arrival path. But if everyone is
excercising normal vigilance, there is nothing intrinsically unsafe
about departing in a direction different from other departures.

You do understand that there is both arriving and departing traffic
at most airports?

Ignoring the established procedures and departing head on into
arriving traffic just because it is "legal" to do so is idiocy.

If the procedure itself is not safe, it needs to be changed.

That is true. But if two different procedures are safe, the pilot gets
to choose which to execute. And if one procedure (say, the noise
abatement one) is not safe under some circumstances, the pilot gets to
use a different procedure. That's what "pilot in command" means.

What part of "if the procedure itself is not safe, it needs to be changed"
are you incapable of understanding?

And as to the alleged safety of a noise abatement procedure, I won't
trust the yahoos who live under a flight path and don't like airplane
noise to decide for me what is safe and what is not. They may well come
up with a safe procedure. They might not. I don't assume it's safe
just because "somebody" came up with it.

What part of "if the procedure itself is not safe, it needs to be changed"
are you incapable of understanding?

The neighbors don't write the noise abatement procedures, that is
normally done by the airport manager.
