I have tried to research this immensely online but cannot find the
answer...so if someone does know this offhand it would be an immense

L-3's (ESIS) on business jets...
it can be incorporated into the ProLine 21 or Primus platform?

How much does an ESIS sell for?

The price will be depending on the aircraft it is going in to, but you
can plan on about $40K for the guage and about another $40K to install
it.

They are there as a backup to the existing systems and therefore by
definition are stand-alone instruments with their own pitot/static and
electrical power sources.

So, it doesn't matter if the aircraft has Proline, Primus or iron
dials you can install these in the panel in place of the three
separate standby airspeed, altitude, and attitude indicators.

Why do we install these?. It gains valuable panel space and these
types of indicators also display backup glideslope, localizer, inbound
course heading, ground speed, distance and time to station, and marker
beacon. Mostly they go in because pilots think they look neat.

Myself, I like the three mechanical backups. Think of it this way, if
the CB panel catches on fire you got nothing.
