Q1) Total distance 3222 nm Q2) 13.4 days Q3) Need 100+ gal, carry 220 gal, so YES Q4) TC 12.3d Q5) Also time of sun's meridian passage, 12 noon LAT Q6) Still 12.3d ( calculated 12.25d) Q7) TC to steer 011.8d, less combined error 11.5 leaves CC to steer 000.3d However as accuracy by plotting is only to nearest degree a CC to steer 000d is more practical. I guess that there must be a way to calculate these questions by trigometric means.
