In the B737-300 simulator of which I am familiar, when the Autobrake selector is switched to RTO as described above (with both electric hydraulic pumps off) the Autobrake Disarm light is illuminated despite what is stated in Vol 1.
However, once Hydraulic System A & B Electric Pump switches are switched on, then after re-cycling the RTO selector from RTO to Off and back to RTO, the Autobrake Disarm light is extinguished. Which is correct given the above circumstances - Vol One or the simulator?
simulator bug !
