The 737-NG is slowly starting to morph into the MAX. Boeing have introduced some of the features of the MAX throttle quadrant onto NGs from l/n 5605. The differences are:

  • The engine start levers have had their first change since the 707. They are now lever-rock toggles switches. They have moved to the left slightly and the lightplate has also been changed. Trivia point for you, the little white cross on the (any) lightplate shows the location of the earthing point behind it. Press it there if the lighting is internittent or goes off.
  • The engine start levers (switches!) will now illuminate when the associated engine fire switch has illuminated.
  • The park brake light is now LED and smaller and has been dropped down by a couple of cm to give more room to operate the Engine 1 start lever/switch.
  • The parking brake lever has been reshaped.
  • The horn cutout button has moved from near the flap 30 detent to the right of the park brake light
