Re-align on the boat?

[Diesel_Thunder]

I’ve searched and could not find out if this was something that could be done (DCS or RL).

Is it possible to re-align the nav while on the boat in the middle of a mission, such as if you landed to rearm/refuel?

[Harlikwin]

Maybe shut down fully and restart? 

IRL IDK, alot of planes needed special equipment to "align" on the boat, harrier is one of em. So its entirely plausible the tomcat did too IRL and maybe thats not entirely reflected in the startup procedure or maybe thats why you can't just align it anywhere.

IRL you can re-align on the boat, sure. Simply turn the INS to OFF, then back to CVA. The same pre-requisites exist as for the initial alignment, I.e. a SINS feed, either via RF/Data link or cable. You can align without the SINS feed, called a Handset alignment, but a handset alignment is a LOT less accurate. The SINS feed provides ship Lat/Long, true heading, speed, and pitch/roll/yaw info to the CSDC. A handset is the RIOs best guess at position, speed and true heading, and no pitch/roll/yaw corrections. Many crews wouldn’t launch at night without a SINS alignment.

Would the handset alignment work fine  on the ground?

You dont need HS alignment on the ground, since your plane is not moving and the current position is known from aerodrome charts.

Right, the only time the system will even accept a handset is in the CVA alignment mode.

Yeah, but AFAIK we don't differentiate this in the DCS cat do we?

 

At any rate it would be nice to have an option for jester to re-align the jet without having to fully shut down/startup.

Yes we do, there are different alignment modes for beach and boat (GND and CVA) , the latter requiring some information on how the boats/ACs position changes during alignment. This can be either  provided by the SINS or derived from an initial position and velocity vector (i.e. HS alignemt).
