Stab Trim question

Recommended Posts

Just a quick question on Stab Trim position. Is there a way to Display it on the EICAS or Pedestal is the only location. I know the 748 displays trim on the EICAS.

 

Thank you

Quick answer:  Nope.  Don't focus on stab trim setting, close enough is plenty good enough.

Is there a way to Display it on the EICAS 

 

 

There is a way on the real aircraft, but it's usually only used by engineers and is in a different format to the normal pedestal display. It shows the stabiliser position input into the 3 Flight Control (Autopilot) computers and the magic boxes which compute the stab trim greenband (on the pedestal indicators).

 

Depending on your Centre of Gravity, wrong stab trim settings of, perhaps, half a unit may trigger EICAS warnings. For example, if the forward (nose down) Greenband is illuminated on your pedestal indicators and your stab trim is 1/2 unit outside the Greenband, you may get a takeoff warning.

 

Cheers
