HSI following great circle navigation

[sandokan]

hi,
I'm looking for a plane with an HSI which reverts its compass from MAG to TRUE in order to give the possibilty to pilots to follow the Horizontal Situation when the plane is driven by GPS or INS.

Isn't a GPS direct-to essentially great circle?

Some of the flight planning apps offer GC autorouting options as well. As long as the waypoints (within 200nm legs) are correct following the path displayed on the HSI should offer great circle facilities.
