  Chapter 8: Flight Instruments › Altimeter Operation

  altimeter indicates an altitude above the actual field elevation. If the barometric pressure setting is reset to the current altimeter setting of 29.68 "Hg, then the field elevation is again indicated on the altimeter. This pressure change ... easily noticed in flight since aircraft fly at specific altitudes. The aircraft steadily decreases true altitude while the altimeter is held constant through pilot action as discussed in the previous section. Knowing the aircraft’s altitude is vitally important…

  Chapter 11: Aircraft Performance › Performance › Rate of Climb (ROC)

  Rate of Climb (ROC) ROC is a comparison of altitude gained relative to the time needed to reach that altitude. ROC is simply the vertical component of the aircraft’s flight path velocity vector. For maximum ROC performance, a pilot ... flies the aircraft at VY so as to achieve a maximum gain in altitude over a given period of time. Maximum ROC expedites a climb to an assigned altitude. This gains the greatest vertical distance over a period of time…

  Chapter 11: Aircraft Performance › Climb Performance Factors › Range Performance

  NOTE: The straight line that is tangent to the sea level power curve is also tangent to the altitude power curve. The effect of altitude on specific range can also be appreciated from the previous relationships. If a change ... altitude causes identical changes in speed and power required, the proportion of speed to power required would be unchanged. The fact implies that the specific range of a propeller-driven aircraft would be unaffected by altitude. Actually, this is true…

  Chapter 8: Flight Instruments › Airspeed Indicator Markings

  Airspeed Indicator Markings Aircraft weighing 12,500 pounds or less, manufactured after 1945, and certificated by the FAA are required to have ASIs marked in accordance with a standard color-coded marking system. This system of color-coded markings enables ... pilot to determine at a glance certain airspeed limitations that are important to the safe operation of the aircraft. For example, if during the execution of a maneuver, it is noted that the airspeed needle is in the yellow…

  Chapter 5: Aerodynamics of Flight › Stalls

  elevator to counteract the excess weight aft of the CG. Without the ability to decrease the AOA, the aircraft continues in a stalled condition until it contacts the ground. The stalling speed of a particular aircraft is not a fixed ... value for all flight situations, but a given aircraft always stalls at the same AOA regardless of airspeed, weight, load factor, or density altitude. Each aircraft has a particular AOA where the airflow separates from the upper surface…

  Chapter 11: Aircraft Performance › Performance › Climb Performance

  Positive climb performance occurs when an aircraft gains PE by increasing altitude. Two basic factors, or a combination of the two factors, contribute to positive climb performance in most aircraft: 1. The aircraft climbs (gains PE) using excess power above ... that required to maintain level flight, or 2. The aircraft climbs by converting airspeed (KE) to altitude (PE). As an example of factor 1 above, an aircraft with an engine capable of producing 200 horsepower (at a given altitude…
