1. The Dome Light Knob in the overhead panel, not like the Panel Light, it's dead and "unturnable". When I key-assign the Dome light with "Ctrl-D", the case is just the same. 2. In 737NG, are there any pushback function, like 747-400, can input the length of pushback and turn a requested angle. 3. Like 747-400, it has EICAS to monitor all the status of the A/C, but I can't find one in the 737NG4. In 747-400, there is TCAS turned, but I can't find any similar things in 737NGMany many questions......737 Newbiedogdog1985
