A few weeks back I was on BA for London-SF flight (which is around
11 hours total time) and since I was seated in the upper deck and
semi-bored I asked one of the flight attendents if I could visit
the cockpit (which, not being US registered, they are allowed to do).

Anyway, this 747 only had one captain and one first officer, but being
what they called a 'long' flight, they carried two flight engineers.
When I asked about this the captian said it was something to do with
hours in a given period, but didn't know the exact details, and the
flight engineer just nodded in a sagely fashion and tapped his

Anyway, the visit was fun. I got a demo of all the fun things they
could do on the Flight Management System, and a demo of the TCAS
display which replaced the rate of climb indicator with a CRT variable
scale rate of climb with the TCAS stuff in the middle. Understandably,
200 nm south of Sonderstrom, it wasn't showing much!

Is TCAS widespread on commercial aircraft? I hadn't seen one before,
and this was on old 747 with main instruments all mechanical, so BA
would seem to have a policy of adding them into existing fleet. Anyone
know of this being done elsewhere?
