Sorry if this has already been asked but let us assume that the TOW was inop would it not be in the T/O checklist to check the flap position indicator? the reason I ask is because some years ago I was the flight mech aboard an American trans air L1011 out of Philadelphia the check were down to the line and the check of the posn indicator was called and the flaps were set at 0 deg. we discovered that the hyd lock-out had activated and the flaps did not deploy even though the handle had been correctly positioned.
