After the engine has been started, if Q or MGT are within the takeoff limitation ranges, the G1000H displays 

a 5-minute countdown timer inside the PSI gauge.  The timer flashes beginning when 30 seconds remain until 
an exceedance will occur; the timer is automatically removed when either Q or MGT fall below takeoff limits.

The dual tachometer displays rotor speed (NR) and power turbine speed (NP) as percentages.   A readout 

for NR is provided.  The long pointer represents NR along the gauge scale; NP is shown with the short pointer.      
Limitations are shown as colored arcs.  A white tick mark represents the FADEC normal governing point.  When 
Quiet Mode is active, a magenta reference bug is shown the tachometer to indicate the Quiet Mode governing 
point.  The NR and NP pointers will be the same color as the arc(s) they are presently within.

During autorotation with an engine failure, the NP pointer will be displayed in gray and the dual tachometer 

gauge scale will display power-off limitations.

If the G1000H is using alternate analog data sources to determine Q, MGT, NG, NP, or NR, a yellow ‘ALTN’ 

annunciation box will appear to the right of the PSI gauge.  In addition, a yellow subscript ‘A’ will be shown with 
the affected parameter readout(s) (Figure 3-6).

In the event an alternate analog data source is unavailable or invalid, a white ‘ALTN’ annunciation box is 

shown to the right of the PSI gauge (Figure 3-6).

If no valid data sources are available, a red ‘X’ is displayed instead of a readout, and any affected pointers will 

be removed from the gauges.
