The 737-300

The most obvious difference of the classics to the originals is that each pilot now has an EADI which displays the artificial horizon, speed tape, LLZ, G/S, Rad alt and MCP annunciations. The EHSI, can display either navaid or route data superimposed with beacons, airfields, FMC route (shown on the LH display), wx radar & TCAS data. The two FMC CDU's are forward of the  throttle quadrant. The centre electronics console is one radio box wider than the originals to accommodate the extra avionics. The original width can be seen by the fire panel.

This particular -300 dates from 1990 so it has the digital EIS display rather than the "round dial" engine instruments. It also has a flap load relief light and had an auxiliary fuel tank which is now removed as can be seen by the blanking plate over the missing fourth fuel gauge and the extra pair of fuel pumps on the overhead panel. Other post 9/11 modifications include a locking flight deck door (aft elec panel) and cctv camera displays of the cabin (between the CDU's). The large white knob in the middle of the electrics panel is a countdown timer.
