Density altitude is

Refer to Figure 19, Low-Level Significant Weather (SIGWX) Prognostic Chart. For an sUAS operation planned between 90°W and 80°W along 40°N according to the 12 HR SIG WX PROG valid at 18Z Sat Apr 14 2012, the moderate turbulence indicated on the chart will most significantly affect performance by

Referring to Figure 15, the PROB40 1220/1222 1SM TSRA OVC008CB in the KMEM TAF represents conditions most likely to produce which primary effect on small unmanned aircraft performance?

Referring to a standard density altitude chart, the approximate density altitude at a pressure altitude of 2,000 feet and an outside air temperature (OAT) of 25°C is

(Refer to Figure 12.) High density altitude reduces small unmanned aircraft performance by decreasing air density. Based on the temperature, dew point depression (humidity), and altimeter setting (pressure) in the METAR reports, which location indicates the highest density altitude?

A small UAS flight is to be conducted from a site at 2,000 feet MSL where the altimeter setting is 29.92 inches of mercury and the air temperature is 30°C. The approximate density altitude is

Referring to the Low-Level Significant Weather (SIGWX) Prognostic Chart in the figure, which condition depicted along 40°N between 90°W and 80°W longitude for the 18Z validity time on April 14, 2012, would most adversely affect the performance of a small unmanned aircraft?

A remote pilot plans a small unmanned aircraft system (sUAS) operation near KMEM within the valid period of the TAF shown in Figure 15. The sUAS performance is most likely to be adversely affected by high density altitude during which KMEM forecast period?

High density altitude conditions MOST affect small unmanned aircraft performance by

(Refer to the provided figure.) The moderate turbulence indicated on the 12 HR SIG WX PROG chart near 80°W would most significantly impact small unmanned aircraft systems (sUAS) performance by

A Remote PIC observes that the current air temperature is higher than standard and the altimeter setting indicates lower than standard pressure. What is the expected effect on small UAS performance?

A remote pilot in command (PIC) is operating a small unmanned aircraft system (sUAS) in conditions of high atmospheric temperature, low pressure, and a stable atmosphere. These conditions will most likely result in

Referring to the Low-Level Significant Weather (SIGWX) Prognostic Chart in the figure, the notation '120' adjacent to certain wind arrows on the 12 HR forecast panel represents
