See above, TIG T1 is calculated only when EL != 0 - otherwise it is free.




... you are aware that

a) any rendezvous is a matching of orbits?
b) you only have spec 34 to calculate a hohmann maneuver?

Rendezvous isn't only matching orbits - you need to be at the some position as the target object. Matching orbits with the target when you're 1000 km behind it doesn't help.

Mission Control can calculate the required DV for a Hohmann transfer and provide it to the crew (this is how the NC1/NC2/NC3 burns are done, although they aren't Hohmann transfers).

Remember orbits also contain the true/mean/eccentric anomaly as parameter describing the position of a spacecraft on the trajectory. This is matched as well. also without mission control you only have SPEC 34 left. SPEC 34 is also related to the REL NAV display

That explains the confusion. I've been referring to orbits as just being SmA/eccentricity/etc. without having any information about position.

Yeah, I also had a small lunch break to think about the relation to the REL NAV mode. Looks like there is a function in this page to update the state vector of the Space Shuttle with radar or Star Tracker data of the tracked target, when its position is known.
