Can we please stop using this term, "alright/ok to have area".
There's no caution in any area of the CAD that's 'OK to have' .... FFS.
Which of the cautions is 'OK to have';
Eng Chip
Eng Oil P
Eng Man
Eng Fail
Starter
Eng Exceed
Any of the Fadec Cautions
FLI Fail/Degr
Fuel Valve
Fuel Press
FuelF Qty Fail/Degr
F Pump Fwd/Aft
F Valve Cl
Prime Pump
XMSN Oil P/T
XMSN Chip
TRGB Chip
Gen Discon
Gen Ovht
Batt Discon
Bustie Open
EPU Door
Inverter
Hyd Press
Pitot Htr
FCS cautions
CAU Degr
Htg Ovtemp
Ext Pwr
Fire Ext
Hor Bat
Rotor Brk
ABSOLUTELY NONE'
I don't believe that anyone that actually flies the real aircraft would be comfortable with any of those above cautions to be displayed, let alone consider them 'OK to have'.
So I say to any observer of this thread, take no notice whatsoever of this term.
