  Chapter 5: Aerodynamics of Flight › Effect of Wing Planform

  root to the tip of the wing). In general, tapering causes a decrease in drag (most effective at high speeds) and an increase in lift. There is also a structural benefit due to a saving in weight of the wing ... Most training and general aviation type airplanes are operated at high coefficients of lift, and therefore require comparatively high aspect ratios. Airplanes that are developed to operate at very high speeds demand greater aerodynamic cleanness and greater strength, which require…

  Chapter 7: Aircraft Systems › Oil Systems

  gauge to show any increase in oil temperature. Check oil temperature periodically during flight especially when operating in high or low ambient air temperature. High oil temperature indications may signal a plugged oil line, a low oil quantity, a blocked ... cooler, or a defective temperature gauge. Low oil temperature indications may signal improper oil viscosity during cold weather operations. The oil filler cap and dipstick (for measuring the oil quantity) are usually accessible through a panel in the engine cowling…

  Chapter 11: Aircraft Performance › Density Altitude

  closer to 1,000 feet. Air density is affected by changes in altitude, temperature, and humidity. High density altitude refers to thin air while low density altitude refers to dense air. The conditions that result in a high density altitude ... high elevations, low atmospheric pressures, high temperatures, high humidity, or some combination of these factors. Lower elevations, high atmospheric pressure, low temperatures, and low humidity are more indicative of low density altitude…

  Chapter 12: Weather Theory › Wind and Currents › Wind Patterns

  Wind Patterns In the Northern Hemisphere, the flow of air from areas of high to low pressure is deflected to the right and produces a clockwise circulation around an area of high pressure. This is known as anticyclonic circulation ... opposite is true of low-pressure areas; the air flows toward a low and is deflected to create a counterclockwise or cyclonic circulation. [Figure 12-10] High-pressure systems are generally areas of dry, descending air. Good weather is typically…

  Chapter 2: Aeronautical Decision-Making › RISK › Hazard and Risk

  Hazard and Risk Two defining elements of ADM are hazard and risk. Hazard is a real or perceived condition, event, or circumstance that a pilot encounters. When faced with a hazard, the pilot makes an assessment of that hazard based ... engine is operated with damage to a prop blade. The seasoned pilot may see the nick as a low risk. He realizes this type of nick diffuses stress over a large area, is located in the strongest portion…

  Chapter 11: Aircraft Performance › Climb Performance Factors › Region of Reversed Command

  which the lowest brake horsepower sustains level flight. This is termed the best endurance airspeed. An airplane performing a low airspeed, high pitch attitude power approach for a short-field landing is an example of operating in the region ... reversed command. If an unacceptably high sink rate should develop, it may be possible for the pilot to reduce or stop the descent by applying power. But without further use of power, the airplane would probably stall or be incapable…
