Jeppesen Private Pilot Handbook,
Chapter 8, Section a Questions
Where can you normally find the performance charts for your airplane? - answerIn the
Performance section of your airplane's POH
Describe how density altitude affects aircraft performance. - answerLow atmospheric
pressure, high temperature, and high humidity all result in decreased air density and a
corresponding increase in density altitude. As density altitude increases, engine
horsepower decreases for normally aspirated engines since the actual amount of air to
support combustion has decreased. In addition, both the wing and the propeller lose
efficiency in the thinner air.
True/False. Takeoff & landing performance depends mainly upon factors that can be
measured or calculated in advance, such as density altitude, pressure altitude,
temperature, wind, aircraft weight, and runway gradient or surface. - answerTrue
Refer to the wind component chart shown below to determine the headwind and
crosswind component for a departure on Runway 18 with a reported wind of 210° at 20
knots. - answerHeadwind: 17 knots; crosswind: 10 knots
What is the runway gradient?
A. The material used to surface the runway
B. The amount of change in runway height over its length
C. The direction of the runway as it relates to magnetic north - answerB
Use the chart shown and the following conditions to determine the ground roll and
distance necessary to clear a 50-foot obstacle.
Conditions:
Pressure Altitude: 6,000 feet
Temperature: 20°C
Flaps: 10°
Runway: Paved, level, and dry
Wind: Calm
Weight: 2,400 pounds - answerGround roll: 1,665 feet; total distance to clear a 50-foot
obstacle: 3,300 feet.
True/False. As altitude increases, the best angle-of-climb speed will decrease, and the
best rate-of-climb speed will increase. - answerFalse
