Anti-collision mechanism

Does this get activated only when there's an aircraft in the dangerous
vicinity or will it also trigger if the aircraft is hurtling towards
some terrain such as a hill?

And does every aircraft have this system these days, regardless of
size?

In my generation of aircraft, (B-727) they are two different systems.
First came the GPWS (Ground Proximity Warning System) and then some
time later came the TCAS (Traffic Alert and Collision Advoidance System).

No, only passenger jets are required to have them.

The military is starting to equip some of their aircraft with TCAS
also:

Then there is the anticollision light system (blinking tail light or
strobes).

You are really talking about two types of systems here. One is for traffic
avoidance, which projects the path of yours and other aircraft and lets you
know if there is a conflict. Some of these systems depict all the aircraft
in the area, along with their direction and altitude, on a moving map.

Terrain avoidance systems warn you of terrain.

No. The systems are very expensive and are typically not found on small
aircraft. However, more of the newer planes do have these systems,
especially the newer glass cockpit displays. There are even some handheld
devices that perform somewhat the same function with more or less
effectiveness. None of them substitute in small planes for a good set of
eyes looking out of the cockpit.

For one thing, traffic avoidance systems usually depend on other aircraft
having transponders, but some people don't turn their transponders on and
some aircraft have no transponders at all.

And now TAWS is surplanting GPWS and EGPWS.

No, only passenger jets are required to have them.

But TAWS and TCAS are now available for smaller GA aircraft.

Shortly, they will be required for turbine aircraft with seven (?) or more
seats.

Well, airline passenger turboprops, too. :-)

Not quite true. All turbine aircraft with over 6 passenger seats are
now required to have a TAWS and a CAS system and virtually all
corporate operators have installed them years ago. I installed TCAS II
in my company Gulfstream before it was even mandated by the airlines.

I haven't seen a corporate jet delivered in the last 20 or so years
that didn't have cockpit equipment much better than any airliner.
Typically, all corporate jets get EGPWS and TCAS with HUD and EVS on
the larger ones.

The ones that come kicking and screaming into the 21st century are the
airlines and charter operators. Because of cost, they won't install
any equipment that is not required for regulation or the route.

I'm a fan of the Mark1 eyeball. It's generally a much undervalued
