SYSTEM (EIS)
3.1  ENGINE DISPLAY
In all cases green indicates normal operation, yellow 
indicates caution, and red indicates warning.
Mooney M20R Engine displays are shown in this sec-
tion.  The M20M displays are similar with the exception of 
showing the Turbine Inlet Temperature (TIT).
Pressing  the  ENGINE  softkey  makes  available  the 
LEAN and SYSTEM softkeys which in turn provide ac-
cess the Lean Page and the System Page, respectively.

The CYL SLCT softkey can be utilized to obtain infor-
mation about a particular cylinder.
The CYL SLCT softkey becomes disabled when a par-
ticular cylinder turns yellow or red, until the temperature 
decreases  and  returns  to  normal  or  when  the  ASSIST 
softkey is pressed.
Pressing the ASSIST softkey causes the first cylinder 
that  peaks  to  become  hightlighted  and  information  for 
that cylinder to be displayed.
Any  exceedance  of  default  Engine  Page  parameters, 
while viewing the Lean Engine Page, will cause the display 
to automatically switch back to the default Engine Page.
