What exactly is the difference between "to", "on" and "via" in the Missed approach icons section of Jeppesen charts? Sometimes "on" is used and sometimes "to" is used. As for the "via", I have no idea. I know the meanings of the words, but I guess I can't understand why they are used differently because English is not my mother tongue.
"TO" means after climbing to 3000 ft on the missed approach track, then proceed to the VOR, the missed approach fix, and pick up the 051ᵒ radial outbound, which will almost certainly has a hold on that radial.
Climb to 2000 while flying ALONG the 044ᵒ radial of the CRL VOR. "ON" means you have to proceed along that particular track to maintain obstacle clearance.
Go from TZK to ITZK while flying along the 111ᵒ radial of TZK while between those two waypoints, but how you get to TZK is up to you. "VIA" refers to a routing between specific waypoints as listed, where you just fly to the first one on your own using the most logical and direct routing.
You could say that the VIA instruction combines the TO instruction (find your way to the 1st waypoint) and the ON instruction (fly between waypoints on a specific track) into a single instruction.
In any case, the detailed instructions are in the MISSED APPROACH block near the top of the approach plate. Those blocks you are referencing are included below the vertical profile of the approach and are shorthand at-a-glance reminders of the key data of the missed approach.
