Narrative:

At FL350; 36 mi from ZZZ; aircraft message 'generator left off;' 'left dc buss off.' captain was the PF. Got QRH out for 'generator left.' followed the checklist; led us to declaring an emergency. We landed at ZZZ airport. Had to manually extend the landing gear as well as manual extension of spoilers. Many other faults occurred as a result of the pcdu failing. Communication #2; transponder #2; ACARS; airspeed indicator; #6 screen in front of manual disconnect; left pack; cabin pressure manual; wing ice failure; pneumatic failure; automatic trim failure; stick pusher failure; GPWS failure; drain mast failure; pitot auxiliary failure; stall warning failure; DME #1 failure; pods fault. We landed in ZZZ and had the gear doors wired closed and then towed to the gate. The QRH for the 'generator left off' has you refer to another section to get proper reference speed for the approach. It would be easier and faster to have that chart on the same page as the 'generator left off' page; rather than going to another section in the QRH. Or maybe if the chart cannot be put on the same page; the page number of the speed chart should be on the 'generator left off' page so to reduce time and error in finding the speed chart. Supplemental information from acn 802214: most troublesome failure was unreliable airspeed indications (foot); and very poor radio communications while on emergency power. ACARS inoperative.

Title: A B717 FLT CREW EXPERIENCED ACFT MESSAGE 'GEN L OFF;' FOLLOWED THE QRH; DECLARED AN EMERGENCY; AND DIVERTED TO THE NEAREST SUITABLE ARPT.

Narrative: AT FL350; 36 MI FROM ZZZ; ACFT MESSAGE 'GENERATOR L OFF;' 'L DC BUSS OFF.' CAPT WAS THE PF. GOT QRH OUT FOR 'GENERATOR L.' FOLLOWED THE CHKLIST; LED US TO DECLARING AN EMER. WE LANDED AT ZZZ ARPT. HAD TO MANUALLY EXTEND THE LNDG GEAR AS WELL AS MANUAL EXTENSION OF SPOILERS. MANY OTHER FAULTS OCCURRED AS A RESULT OF THE PCDU FAILING. COM #2; XPONDER #2; ACARS; AIRSPD INDICATOR; #6 SCREEN IN FRONT OF MANUAL DISCONNECT; L PACK; CABIN PRESSURE MANUAL; WING ICE FAILURE; PNEUMATIC FAILURE; AUTO TRIM FAILURE; STICK PUSHER FAILURE; GPWS FAILURE; DRAIN MAST FAILURE; PITOT AUX FAILURE; STALL WARNING FAILURE; DME #1 FAILURE; PODS FAULT. WE LANDED IN ZZZ AND HAD THE GEAR DOORS WIRED CLOSED AND THEN TOWED TO THE GATE. THE QRH FOR THE 'GENERATOR L OFF' HAS YOU REFER TO ANOTHER SECTION TO GET PROPER REF SPD FOR THE APCH. IT WOULD BE EASIER AND FASTER TO HAVE THAT CHART ON THE SAME PAGE AS THE 'GENERATOR L OFF' PAGE; RATHER THAN GOING TO ANOTHER SECTION IN THE QRH. OR MAYBE IF THE CHART CANNOT BE PUT ON THE SAME PAGE; THE PAGE NUMBER OF THE SPD CHART SHOULD BE ON THE 'GENERATOR L OFF' PAGE SO TO REDUCE TIME AND ERROR IN FINDING THE SPD CHART. SUPPLEMENTAL INFO FROM ACN 802214: MOST TROUBLESOME FAILURE WAS UNRELIABLE AIRSPD INDICATIONS (FOOT); AND VERY POOR RADIO COMS WHILE ON EMER PWR. ACARS INOP.
