The input to the PERF INIT page data used by FMC to calculate the performance of vertical plane. See in the LEGS page climb and cruise forecast data is derived from this information. When an entry or near the route down to the LEGS page limit compilation, FMC will calculate the decline, and in the LEGS page generation decline forecast data. Press the VNAV key on the CDU out of the VNAV page. VNAV has three pages are available, climb, cruise and descent stage. The current page is determined by the phase of flight. At the top of climb (T/C) before press the VNAV button to display the VNAV CLB page. In the T/C and decreased the vertex (T/D) between the press the VNAV button to display the VNAV CRZ page.

When VNAV is the current AFDS mode, EADI will display the VNAV SPD or VNAV PTH. VNAV SPD said the speed of the aircraft is to keep the aircraft pitch. The pattern of decline in VNAV or VNAV (speed climbing intervention model) when switched on. VNAV PTH said the aircraft speed is used to keep the thrust. This pattern in all levels during the recovery of VNAV and VNAV channel decline during the connection. VNAV. According to the FMC input to the VNAV CLB page and LEGS page data to construct a VNAV profile. VNAV is by pressing the VNAV button on the MCP connection after take-off.
