NavList:

I've asked that same question several times in the past and no one has an answer.

On another releated subject, the online version of H.O 249 still has the errors that I notified the government of 6 months ago, too much of a computer problem to correct?.

I asked this question in an earlier reply to Jeremy (Exercise #9 Star
Time), but I think it got buried in all the other discussion so I'll
post it as its own topic to see if anyone on the list has a definitive
answer for it:

  

229 is just too slow with multiple LOP's
    

I've never figured out why 229 is LHA-based (instead of being
latitude-based as 249 is). Since you're going to use the same assumed
latitudes for a fix (or I guess maybe nearby latitudes, if a lot of
time passes between fixes) why should you have to flip to a different
page in the tables for each fix?

Might have something to do with the computer program used to generate
the tables, but I'd also assume that the output could be setup in
whatever format was desired by the end-user.
