You are about to take a VFR flight in Summer with no serviceable radio aids on board your aircraft. The flight is likely to occur in haze in the late afternoon, with the Sun deteriorating visibility even more. Which route should you plan to take?
VFR navigation is highly affected by the choice of route, and particularly features to use for turning points or tracking.
In this case, with quite poor visibility, due to the haze and the Sun to the West, the best way to navigate given here is to use the large line features of the highway and the river, which can be followed all the way to the destination.
It does not add too much distance to the route, but does make sure that the pilot will always know their position and will not become lost or disorientated.
The VOR cannot be used for navigation due to the lack of serviceable equipment on the aircraft.
The tall mast may be an acceptable turning point, but might be difficult to identify in the Sun and the haze, and the long legs with reduced visibility could lead the aircraft to being off course and have a higher chance of getting the pilot lost than following the highway and river.
The 4th route is not even on the map, and is similar to using the mast, though it is much likely easier to find, but is large and therefore less accurate as a position fix.
