What is density altitude?

Correct! Wrong!

(Refer to Figure 8.) Determine the pressure altitude at an airport that is 3,563 feet MSL with an altimeter setting of 29.96.

Correct! Wrong!

(Refer to Figure 8.) Determine the density altitude for these conditions: Altimeter setting.......................30.35 Runway temperature.....................+25 °F Airport elevation................3,894 ft MSL

Correct! Wrong!

(Refer to Figure 8.) Determine the pressure altitude at an airport that is 1,386 feet MSL with an altimeter setting of 29.97.

Correct! Wrong!

(Refer to Figure 35.) Approximately what true airspeed should a pilot expect with 65 percent maximum continuous power at 9,500 feet with a temperature of 36 °F below standard?

Correct! Wrong!

(Refer to Figure 35.) Determine the approximate manifold pressure setting with 2,450 RPM to achieve 65 percent maximum continuous power at 6,500 feet with a temperature of 36 °F higher than standard.

Correct! Wrong!

(Refer to Figure 35.) What fuel flow should a pilot expect at 11,000 feet on a standard day with 65 percent maximum continuous power?

Correct! Wrong!

Under which condition will pressure altitude be equal to true altitude?

Correct! Wrong!

What effect, if any, does high humidity have on aircraft performance?

Correct! Wrong!

Which factor would tend to increase the density altitude at a given airport?

Correct! Wrong!

(Refer to Figure 8.) Determine the density altitude for these conditions: Altimeter setting.....................29.25 Runway temperature...................+81 °F Airport elevation..............5,250 ft MSL

Correct! Wrong!

What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?

Correct! Wrong!

In the less dense, or thinner, air the propeller cannot exert the same force as it does in more dense air. Answer A is incorrect because less friction of air on the rotating propeller blades is a very minor factor. Answer C is incorrect because the efficiency of the propeller is reduced in less dense air, since it is unable to exert as much force as it could in more dense air.

(Refer to Figure 8.) What is the effect of a temperature increase from 35 to 50 °F on the density altitude if the pressure altitude remains at 3,000 feet MSL?

Correct! Wrong!

(Refer to Figure 8.) What is the effect of a temperature increase from 25 to 50 °F on the density altitude if the pressure altitude remains at 5,000 feet?

Correct! Wrong!

(Refer to Figure 8.) Determine the pressure altitude with an indicated altitude of 1,380 feet MSL with an altimeter setting of 28.22 at standard temperature.

Correct! Wrong!

If the outside air temperature (OAT) at a given altitude is warmer than standard, the density altitude is

Correct! Wrong!

What effect does high density altitude have on aircraft performance?

Correct! Wrong!

(Refer to Figure 8.) What is the effect of a temperature decrease and a pressure altitude increase on the density altitude from 90 °F and 1,250 feet pressure altitude to 55 °F and 1,750 feet pressure altitude?

Correct! Wrong!

Under what condition is pressure altitude and density altitude the same value?

Correct! Wrong!

(Refer to Figure 35.) What is the expected fuel consumption for a 500-nautical mile flight under the following conditions? Pressure altitude........................4,000 ft Temperature...............................+ 29 °C Manifold pressure........................21.3" Hg Wind.........................................Calm

Correct! Wrong!

Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance?

Correct! Wrong!
