  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 5: Aerodynamics of Flight › Ground Effect

  Figure 5-16. Ground effect changes airflow. Ground effect also alters the thrust required versus velocity. Since induced drag predominates at low speeds, the reduction of induced drag due to ground effect will cause a significant reduction of thrust required ... downwash, and wingtip vortices, there may be a change in position (installation) error of the airspeed system associated with ground effect. In the majority of cases, ground effect causes an increase in the local pressure at the static source…

  Figure 2-3, Figure 2-4, and Figure 2-5 layout a sample assessment. Figure 2-3 shows how entries might look in the Experience & Comfort Level Assessment VFR & MVFR table. Suppose a pilot’s flying takes place ... part of the country where clear skies and visibilities of 30 miles or more are normal. The entry might specify the lowest VFR ceiling as 7,000 feet, and the lowest visibility as 15 miles. A pilot may never experience…

  most common errors is failing to move to lower levels of automation suitable to a changing environment. 12292 For example, a pilot may track an approach course adequately using manual control inputs. However, the pilot may also need to listen ... ATIS), retrieve and load an instrument approach procedure, prepare for the instrument approach, and accomplish the appropriate checklists. These tasks will increase workload and divert pilot attention from monitoring and controlling the flight path. If using an autopilot to track…

  Chapter 8: Flight Instruments › Setting the Altimeter

  this reason, a generous margin of altitude should be allowed—not only for possible altimeter error, but also for possible downdrafts that might be associated with high winds. To illustrate the use of the altimeter setting system, follow a flight ... altimeter setting window. The altimeter indication should then be compared with the known airport elevation of 487 feet. Since most altimeters are not perfectly calibrated, an error may exist. When over Mineral Wells, assume the pilot receives a current altimeter…

  cruising altitude or flight level. Unless otherwise authorized by ATC, the following rules apply— (a) In controlled airspace. Each person operating an aircraft under IFR in level cruising flight in controlled airspace shall maintain the altitude or flight level assigned ... that aircraft by ATC. However, if the ATC clearance assigns “VFR conditions on-top,” that person shall maintain an altitude or flight level as prescribed by § 91.159. (b) In uncontrolled airspace.
