INTRODUCTION 

The EASy system provides speed protection devices and associated warnings, in order to the 
airplane staying within its normal flight envelope. 

DEFINITIONS 

LOW SPEED CUES (LSC) 

At the bottom of the speed scale of the Attitude Director Indicator (ADI), two cues, one 
amber and one red, are displayed at low speed. They are also displayed on the HUD 
(optional). 

 

FIGURE 02-22-15-00  LOW SPEED CUES ON ADI SPEED SCALE 

Low speed cue (amber) 

The amber low speed cue indicates an operational speed limit that includes preset stall 
margins. The length of the amber low speed cue will vary when the airplane configuration 
changes (SF1, SF2, SF3). 

When the load factor is increased and auto pilot is off, the upper edge of the amber cue 
will not move up.
