The Four fundamentals
The exact instrument scan pattern to use depends on the maneuver you want to perform. All possible maneuvers of an airplane have only four fundamental components. The four fundamentals are
- straight and level
These components, alone or in combination, cover all possible flying maneuvers.
For each maneuver, there is one instrument that gives the primary indication of pitch performance, one instrument that gives the primary indication of bank performance, and one instrument that gives the primary indication of power performance.
Table 12.1 shows the primary pitch, bank, and power instruments for different maneuvers. On those maneuvers where manifold pressure or tachometer is listed as the primary power instrument, the tachometer is primary where the aircraft realism is selected to simulate a fixed-pitch propeller and manifold pressure is primary where the simulation realism is selected to simulate a constant-speed propeller.
