Hi Shipmates,
Here is a complicated issue - or maybe its a non-issue that Ive made complicated:
When using a calculator to find Hc, does one enter the same whole numbers that are used when looking up Hc/d/Z in 249/229? Or does one enter into the formula an APLAT, DEC, and LHA with decimal values (degrees:minutes:seconds) included?
I mean, as I try to think logically about this, if you can create your own assumed position (AP) wherever you like, then you can place the AP as close to the DR as you like, and as close to the body's Zn as possible. Then the LOP would consistently line up very near the actual HO position reducing error a great deal (as long as the actual position is relatively close to DR).
The same question applies to finding Z...
Tell me what you think!
Joe
