KING AIR C90GTi/C90GTx PILOT TRAINING MANUAL
FOR TRAINING PURPOSES ONLY
16-5
The Low Speed Cue / Impending Stall Speed
(LSC / ISS) bar is displayed at the AFM value
for stall at a maximum gross weight, power
idle and no bank condition (Figure 16-6).
Figure 16-6. Low Speed Cue
This speed is adjusted for flap position as listed
here:
• 0% Flaps – 88kts s
• 40% Flaps –
83kts
• 100% Flaps – 78kts
It is important to note that these speeds are
not adjusted for the current g-forces, power
settings or maneuvers. They should be used as
reference only and not as the primary indica-
tion of a stall. The true indication of a stall will
be in the form of a stall horn, or aerodynamic
buffet. The autopilot will not stop the aircraft
airspeed from getting into the low speed cue
but once the stall warning horn sounds the au-
topilot will disconnect. See the Stall Warning
section later in this chapter.
The high speed cue consists of a red bar start-
ing at the current Vmo or Mmo whichever is
appropriate (Figure 16-7). Should the aircraft
actual airspeed enter this red bar area an over-
speed warning horn will sound until the speed
is reduced to below the red overspeed bar. If
the autopilot is engaged during the overspeed,
it will begin to pitch the aircraft up until
achieving an airspeed just below the current
Vmo or Mmo.
Figure 16-7. High Speed Cue
Displayed above the airspeed tape, is a Speed
reference that the pilot can set using the speed
knob on the Flight Guidance Panel. A bug will
appear on the tape next to the selected speed
(Figure 16-8).
