Tcas Not Standard?

Tue Dec 27, 2005 11:43 pm

As I just came across an article in a newspaper saying that a mid-air crash was avoided because one of the aircraft was equipped with TCAS, I was asking myself if this system was not a standard in all civil aircraft.

In this case a DC9 from Aeropostal, that was enroute from Caracas to Puerto Ordaz received a warning by TCAS. An aircraft of another (not mentioned) airline had a loss of cabin pressure and left its cruising altitude until finally being on the same level as the VH aircraft.
Due to the warning system the VH pilot could react and change his route to avoid a crash.

I am sure that all new aircraft are equipped with TCAS, but there seem to be some older ones that don't have TCAS. Why is there no international regulation forcing ALL airlines to put the system in their older aircraft ?

Some DC9's don't have Tcas....It depends on the original owner.

It was not standard on the aircraft and was an extra that airlines added.

Some countries do not require aircraft to have TCAS.

Brazil/Bolivia/Most of Africa/Central Asia - Not required.

India is the ONLY country that requires ALL aircraft have TCAS.
Aircraft without TCAS are subject to escort at Inflated fees.

In Oz RPT (Regular Public Transport) aircraft with 30 seats or more are the only aircraft required to have TCAS (at the moment). Our Metro 23's do not require TCAS yet they scoot along quicker than our Saabs do.

Maybe the 2nd aircraft mentioned above, was a Kingair, B1900, M23, E120 or similar type that wasn't required like a lot of other countries.

For a long time TCAS was not required on freighters or military transports, but a couple of spectacular near misses and a midair off the west coast of Africa between a Luftwaffe TU-154 and a USAF C-141B changed that.
The most spectacular near miss, I know of, was been a Kaletta L-1011 and a FedEx DC-10. They were both at 350 on crossing tracks over the central US (Kansas??) when the controllers realized the possible conflict, but they couldn't make radio contact. The controllers watched as the target merged. The DC-10 crossed in front of the L-1011 filling the windshield with airplane.
A real skivey stainer for the Kaletta crew.
