The PERF MENU allows to access several sub-pages to configure performance parameters
• PERF INIT // LSK 1L
Opens the performance initialization page – see respective section for further information
• VNAV SETUP // LSK 2L
Opens the VNAV sub-pages – see respective section for further information
• FLX TEMP // LSK 4L
As the FADEC automatically computes the thrust setting for each throttle detent, entering a flex
temperature simulates a higher ambient temperature which leads to a thrust reduction. The flex
temperature depends on the runway length, aircraft weight and further parameters. Accordingly, the
flex temperature is either determined using a plethora of charts and tables or using highly
sophisticated IT tools. TOPCAT by FSS is the only flightsim-tool being basically capable of computing
takeoff performance. Currently there is no CRJ profile available though.
• ADVISORY VNAV // LSK 5L
Toggles the advisory VNAV off or on
• VNAV PLAN SPD // LSK 6L
Indicates the speed, the FMS is using as soon as VNAV PLAN SPD is activated
• FUEL MGMT // LSK 1R
Opens the FUEL MGMT, fuel management, sub-pages – see respective section for further information
• FLT LOG // LSK 2R
Opens the FLT LOG, flight log, sub-pages – see respective section for further information
• SEC PERF // LSK 4R
Opens the performance pages related to the secondary flight plan.
