What effect, if any, does high humidity have on aircraft performance?
It decreases performance. Humidity will have the same effect as low pressure or high temperature, aka it will increase the density altitude and affect performance negatively.

What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?
Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes. Density Altitude is the altitude corrected for non-standard pressure and non-standard temperatures. A high density altitude means your UAS will "feel" like it's operating at a higheRead more

See lessDensity Altitude is the altitude corrected for non-standard pressure and non-standard temperatures. A high density altitude means your UAS will “feel” like it’s operating at a higher altitude, hence the performance will be diminished.
What effect does high density altitude have on the efficiency of a UA propeller?
Propeller efficiency is decreased. Density Altitude is the altitude corrected for non-standard pressure and non-standard temperatures. A high density altitude means your UAS will "feel" like it's operating at a higher altitude, hence the performance will be diminished.

How would high density altitude affect the performance of a small unmanned aircraft?
Decreased performance. Density Altitude is the altitude corrected for non-standard pressure and non-standard temperatures. A high density altitude means your UAS will "feel" like it's operating at a higher altitude, hence the performance will be diminished.

Which of the following considerations is more relevant to a Remote PIC when evaluating unmanned aircraft performance?
Current weather conditions. The current weather will dictate the performance of the aircraft. Density altitude is affected by temperature and pressure changes.

Which factor would tend to increase the density altitude at a given airport?
An increase in ambient temperature. Density altitude increases with an increase in temperature, a decrease in pressure, and/or an increase in humidity.
An increase in ambient temperature.
Density altitude increases with an increase in temperature, a decrease in pressure, and/or an increase in humidity.

The chart shows a gray line with "VR1667, VR1617, VR1638, and VR1668" Could this area present a hazard to the operations of a small UA? (Area 2)
Yes, this is a Military Training Route from the surface to 1,500 feet AGL and below. VR lines are Military Training Routes (MTR) so you should expect low altitude flying at very high speeds.
