  useful consciousness because oxygen in the lungs is exhaled rapidly, reducing pressure on the body. This decreases the partial pressure of oxygen in the blood and reduces the pilot’s effective performance time by one-third to one-fourth ... Cabin pressurization instruments. The primary danger of decompression is hypoxia. Quick, proper utilization of oxygen equipment is necessary to avoid unconsciousness. Another potential danger that pilots, crew, and passengers face during high altitude decompressions is evolved gas decompression sickness. This…

  aircraft leaving ground effect after takeoff encounters just the reverse of an aircraft entering ground effect during landing. The aircraft leaving ground effect will: • Require an increase in AOA to maintain the same CL • Experience an increase in induced drag ... nose-up change in moment • Experience a reduction in static source pressure and increase in indicated airspeed Ground effect must be considered during takeoffs and landings. For example, if a pilot fails to understand the relationship between the aircraft…

  Effect of Pressure on Density Since air is a gas, it can be compressed or expanded. When air is compressed, a greater amount of air can occupy a given volume. Conversely, when pressure on a given volume ... doubled; if the pressure is lowered, the density is lowered. This statement is true only at a constant temperature. Effect of Temperature on Density Increasing the temperature of a substance decreases its density. Conversely, decreasing the temperature increases the density…

  necessary, the operator may divide the passenger cabin into subsections or zones and manage the loading of each zone individually. It can be assumed that passengers will be sitting uniformly throughout each zone. Figure 9-49. Determining ... cabin aircraft with high-density seating such as the B737-800, the operator must account for the seating of passengers in the cabin [Figure 9-50]. If assigned seating is used to determine passenger location, the operator must implement procedures…
