right, obi-wan probably doesn't get to be a pilot too much. general sounds like ground troops to me. however, in ANH, obi-wan demonstrates that he does have a keen knowledge of space flight and ships in general.
"there's another ship coming in" (solo)
"he followed us!" (luke)
"no, it's a short-range fighter" (kenobi)
"a fighter that size couldn't get this deep into space on it's own" (kenobi)
"he must have gotten lost, been part of a convoy or something" (luke)
"well, he's not going to be around long enough to tell anyone about us" (solo)
"it would be just as well to let him go, he's too far out of range" (Kenobi)
"not for long, chewie, jam his transmition" (solo)
"aaargghhh" (chewie) 🙂
"looks like he's heading for that small moon" (luke)
"i think i can get him before he gets there, he's almost in range" (solo)
"that's no moon, it's a space station!" (kenobi)
okay, i'll stop. here we see that kenobi (1) can tell what range a ship has by just looking at it, (2) knows how deep into space they are, (3) knows just by looking that it is out of range of solo's guns, (4) and recognizes the space station before anyone else.
he may not be a pilot at the same level as anakin (he was the best starpilot in the galaxy, and a cunning warrior), but kenobi seems to know his way around.
