The FTL Jump process on the Galactica has several safeguards, all appropriate for a ship of that size and an action of that danger (late in the series, we see that an inappropriate jump can cause major damage to nearby objects).  Only senior officers can start the process, multiple teams all sign off on the calculations, and dedicated computers are used for potentially damaging computations.

Even the actual ‘jump’ requires a two stage process with an extremely secure key and button combination.  It is doubtful that Lt. Gaeta’s key could be used on any other ship aside from the Galactica.

The process is so effective, and the crew is so well trained at it, that even after two decades of never actually using the FTL system, the Galactica is able to make a pinpoint jump under extreme duress (the beginning of human extinction).

Difficult Confirmation

The one apparent failure in this system is the confirmation process after the FTL jump.  Lt. Gaeta has to run all the way across the CIC and personally check a small screen with less than obvious information.

Of the many problems with the nav’s confirmation screen, three stand out:

• It is a 2d representation of 3d space, without any clear references to how information has been compacted
• There are no ‘local zero’ showing the system’s plane or relative inclination of orbits
• No labels on data

Even the most basic orbital navigation system has a bit more information about Apogee, Perigee, relative orbit, and a gimbal reading. Compare to this chart from the Kerbal Space Program:

The Galactica would need at least this much information to effectively confirm their location.  For Lt. Gaeta, this isn’t a problem because of his extensive training and knowledge of the Galactica.  

But the Galactica is a warship and would be expected to experience casualties during combat.  Other navigation officers and crew may not be as experienced or have the same training as Lt. Gaeta.  In a situation where he is incapacitated and it falls to a less experienced member of the crew, an effective visual display of location and vector is vital.

Simplicity isn’t always perfect

This is an example of where a bit more information in the right places can make an interface more legible and understandable.  Some information here looks useless, but may be necessary for the Galactica’s navigation crew.  With the extra information, this display could become useful for crew other than Lt. Gaeta.
