VFR navigational charts?

Question

What does a straight line on a VFR navigational chart represent?

Answer 1

Depends on the chart projection. Your VFR chart is most likely a Lambert conformal conic projection (check the small print on the chart). In this case a straight line is approximately a great circle track (but not exact unless the line is north - south).

Answer 2

There are many straight lines on a VFR chart. Be more specific please.

Answer 3

your planned course

Answer 4

On a sectional chart it represents, with very little distortion, part of a great circle.

[Use a straight edge or a taught thread and see how closely it matches longitudinal meridians and long airway segments].

Answer 5

A straight line printed on the chart?  More details, please.  It could be a line of latitude or longitude, or it could be an isogonic line showing magnetic variation.
