Private Pilot Written Practice Questions And Answers 2024 Latest Solutions What is the approximate base of the cumulus clouds if the surface air temperature at 1,000 feet MSL is 70°F and the dewpoint is 48°F? ANS When lifted, unsaturated air cools at approximately 5.4°F per 1,000 feet. The dew point cools at approximately 1°F per 1,000 feet. Therefore, the convergence of the temperature and dew point lapse rates is 4.4°F per 1,000 feet. The base of a cloud (AGL) that is formed by vertical currents can be roughly calculated by dividing the difference between the surface temperature and the dew point by 4.4 and multiplying the rounded result by 1,000. 1. 70°F surface temperature - 48°F dew point = 22°F 2. 22 ÷ 4.4 = 5 3. 5 x 1,000 = 5,000 feet AGL 4. 5,000 feet AGL + 1,000 feet field elevation = 6,000 feet MSL Under what conditions may objects be dropped from an aircraft? ANS No pilot-in-command of a civil aircraft may allow any object to be dropped from an aircraft in flight that creates a hazard to persons or property. However, this does not prohibit the dropping of any object if reasonable precautions are taken to avoid injury or damage to persons or property. When converting from true course to magnetic heading, a pilot should ANS When converting a true course to a true heading, subtract a left wind correction angle or add a right wind correction angle. When converting from a true heading to a magnetic heading, add westerly variation or subtract easterly variation. The left turning tendency of an airplane caused by P-factor is the result of the ANS The downward-moving blade on the right side of the propeller has a higher angle of attack and greater action and reaction than the upward moving blade on the left. This results in a tendency for the airplane to yaw around the vertical axis to the left. One weather phenomenon which will always occur when flying across a front is a change in the ANS Wind direction always changes across a front. precipitation does not always exist with a front. the stability on both sides of the front may be the same.
