The G3X Touch will not support the display of flight director command bars
, autopilot modes or other annunciation for non-Garmin autopilots.
While in IFR cruise at 4000 feet, the pilot observed the flight director command bars
move out of view as the airplane started a gradual descent.
However, that first block might also send its notion of what the airplane needs to do to track as selected, to "command bars" located on the attitude indicator.
There are two common types of command bars. The original (split-que) is essentially crosshairs (shown to the right), where you pitch to maintain the horizontal bar on the aircraft representation, and roll to center the vertical bar.
If so, pressing it disengages the autopilot (if it's on) and moves the flight director command bars
to a wings-level, seven-to-10-degree nose-up attitude, which is close to optimal climb attitude for many airplanes.
The system also has a flight director, so the magenta-colored command bars are placed over the G5's attitude display.
The GDU620 (that's the display used in the G500/600 system) shows the autopilot's mode annunciation and alerts, plus it displays flight director command bars. It's also used for altitude preselect and heading command, plus the ESP circuitry uses the display for bank limit reference.
There are two ways to use a FD: Hand-fly the aircraft using guidance information provided by its command bars
or engage the autopilot to use the same guidance information.
The EFD1000 also displays single-cue flight director command bars
when interfaced with the Bendix/King KI256 FD gyro.
Most modern flight directors add two visual elements to the airplane's attitude indicator: a wedge-shaped aircraft symbol (replacing the wings-style airplane symbol on most attitude indicators and artificial horizons), and command bars
, a pair of symbols that form an inverted V-shape.
The pilot can follow the commands of the flight director by handling the yoke and pitching or rolling the airplane to put the triangular aircraft symbol inside the complementary triangular space under the flight director command bars
. (GFC 700 systems in turboprop and jet installations have another flight director style option, the older style two-bar display which looks like the two crosshairs of an ILS.)
Some pilots advocate setting the heading bug, and therefore the flight director command bars
, to the initial heading or route.
