1 Warm-Up – 12/5 – 10 minutes Utilizing your notes and past knowledge answer the following questions: Describe the mixture of gases in the atmosphere. What is the standard pressure at sea level? Describe why its is difficult for aircraft to take off on a hot day. Describe why the speed of sound varies with altitude. Describe what is a stall.

2 Questions / Comments

3 Warm-Up – 12/5 – 10 minutes Utilizing your notes and past knowledge answer the following questions: Describe the mixture of gases in the atmosphere. What is the standard pressure at sea level? Describe why its is difficult for aircraft to take off on a hot day. Describe why the speed of sound varies with altitude. Describe what is a stall.

4 The Realm of Flight The layers of the atmosphere:
Troposphere, stratosphere, mesosphere, thermosphere, and exosphere The atmosphere is a mixture of gases 79% nitrogen 21% oxygen 1% of other gases The atmosphere extends to about 100 miles (approx. 528,000 ft)

5 Warm-Up – 12/5 – 10 minutes Utilizing your notes and past knowledge answer the following questions: Describe the mixture of gases in the atmosphere. What is the standard pressure at sea level? Describe why its is difficult for aircraft to take off on a hot day. Describe why the speed of sound varies with altitude. Describe what is a stall.

6 Pressure Top layer of atmosphere has less pressure
Pressure is greatest at Earth’s surface Pressure decreases with increase in altitude “Standard Pressure” is 14.7 psi or inches

7 Warm-Up – 12/5 – 10 minutes Utilizing your notes and past knowledge answer the following questions: Describe the mixture of gases in the atmosphere. What is the standard pressure at sea level? Describe why its is difficult for aircraft to take off on a hot day. Describe why the speed of sound varies with altitude. Describe what is a stall.

8 Density Air at higher altitudes has less pressure – it is also less dense. Density is also related to temperature. As air is heated, the molecules move farther apart Which means there is a decrease in density On a hot day, aircraft in high altitudes have difficulty taking off – air is too thin

9 Warm-Up – 12/5 – 10 minutes Utilizing your notes and past knowledge answer the following questions: Describe the mixture of gases in the atmosphere. What is the standard pressure at sea level? Describe why its is difficult for aircraft to take off on a hot day. Describe why the speed of sound varies with altitude. Describe what is a stall.

10 The Speed of Sound in Air
Austrian physicist Ernst Mach determined the mathematical value for the speed of sound Speed of sound varies with altitude because temperature decreases with an increase in height Chuck Yeager in the X-1 broke the speed of sound Oct 14, 1947

11 Warm-Up – 12/5 – 10 minutes Utilizing your notes and past knowledge answer the following questions: Describe the mixture of gases in the atmosphere. What is the standard pressure at sea level? Describe why its is difficult for aircraft to take off on a hot day. Describe why the speed of sound varies with altitude. Describe what is a stall.

12 Real World Lift and Weight
Turbulence reduces the efficiency of the airfoil Stalls When the air next to a wing’s surface separates, it flows more slowly and loses its lift capability
