Re: Question re. Antonov An-148

There is a switch NAV1/NAV2/GPS, which suggests that there must be a way to set LNAV and switch it to ILS at arrival, but there is no NAV button per se, at least in the JarDesign incarnation of the aircraft - which does seem to be the same as the few pictures of the cockpit I have found, though as w...

Question re. Antonov An-148

Anyone know how this a/c engages its lateral mode (LNAV)? I haven't been able to find a close-up photo quite detailed enough to confirm, but although there is a VNAV button on the MCP, I am pretty sure, I don't see one for LNAV. Similarly, one incarnation of this aircraft for X-Plane has no LNAV fun...
