C560XL CREW NOTES EMER CHKLISTS PROVIDED BY THE ACFT MANUFACTURER ARE DIFFICULT TO USE; DON'T FLOW; AND ARE NOT PLT FRIENDLY TO USE IN AN EMER SIT.

Narrative

AFTER TKOF ON RWY 35L AT DEN THE MASTER CAUTION SYS BEGAN TO CYCLE ON/OFF CLBING THROUGH 12000 FT ON DEP. IT WOULD NOT CANCEL. IT WAS CAUSED BY A CYCLING ACCESSORY DOOR WARNING LIGHT. BOTH PLTS UNDERSTOOD ATC HAD CLRED OUR FLT FOR A VISUAL APCH TO RWY 35L AFTER WE REQUESTED A RETURN TO DEN. WE LINED UP TO FOLLOW TFC WE BELIEVED WE WERE SUPPOSED TO FOLLOW AND WERE SURPRISED WHEN THE TWR INFORMED US WE WERE SUPPOSED TO LAND ON RWY 35R. WE DID SO WITHOUT FURTHER INCIDENT. IN RETROSPECT I BELIEVE THE MANUFACTURER PROVIDED CHKLISTS ARE AT THE ROOT OF OUR MISCOM WITH ATC. DURING THE 5 MINS FROM THE ONSET OF THE EVENT TO LNDG WE HAD TO VISIT 7 SECTIONS OF A PHYSICALLY DIFFICULT TO USE; 3/4 INCH THICK; BOOKLET STYLE CHKLIST. ITS FULL OF NON ESSENTIAL VERBIAGE THAT; DURING TIME CRITICAL EVENTS; INCREASE CREW WORKLOAD AND OPPORTUNITY FOR ERROR. AS AN EXAMPLE; IT IS NOT INTUITIVE TO LOCATE A 'DOOR CAUTION LIGHT' BY TURNING TO 'TAB V-5.' ONE MUST FIRST VISIT AN INDEX THAT GOES ON AND ON FOR PAGES. THE 'GAMA' CHKLIST FORMAT AND THE VERBIAGE CHOSEN BY THE MANUFACTURER IS BEST UNDERSTOOD IF YOU PUT YOURSELF IN THE SHOES OF THE MANUFACTURER'S LAWYER. SOME HUMAN FACTORS STUDY OF THE VALUE OF SUCH CHKLISTS WOULD BE MOST USEFUL. IT WOULD BE INTERESTING TO SEE WHAT A CREDENTIALED HUMAN FACTORS; CRM KNOWLEDGE GROUP (SUCH AS THE NASA/UNIVERSITY OF TEXAS GROUP) WOULD DERIVE FROM A STUDY OF BUSINESS JET COCKPIT CHKLIST DEVELOPMENT.
