Al,

I don't understand your reluctance to putting the gear up warning mico 
switch on your throttle?  Whether your air cooled , water cooled or use 
dylithium crystles,  you gonna have the throttle near closed in 99% of the 
cases when on final.

My up&locked nose gear micro is triggered by the gear door actuator.  If 
the nose doors are up, the nose gear has to be?.
