Figure 7-12. Speed versus pivotal altitude. Distance from the pylon affects the angle of bank. At any altitude above that pivotal altitude, the projected reference line appears to move rearward in a circular path in relation to the pylon ... Conversely, when the airplane is below the pivotal altitude, the projected reference line appears to move forward in a circular path. [Figure 7-13] To demonstrate this, the pilot will fly at maneuvering speed and at an altitude below…
- 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 7: Ground Reference Maneuvers › Elementary Eights › Eights Around Pylons
Eights Around Pylons Eights around pylons is a ground reference maneuver with the same principles and techniques of correcting for wind drift as used in turns around a point and the same objectives as other ground track maneuvers. Eights around ... pylons utilizes two ground reference points called “pylons.” Turns around each pylon are made in opposite directions to follow a ground track in the form of a figure 8. [Figure 7-9] Figure 7-9. Eights around pylons. The pattern…
