CONFIRM INIT and vertical profile

CONFIRM INIT appears on PERF INIT 3/3 when required fields are complete. Select it with 6R; the prompt changes to PERF DATA. The vertical profile is unavailable until confirmation ^[24].

Changing PERF INIT data brings CONFIRM INIT back. Confirm again before using the recalculated profile ^[24].

The PERF index also lists DES FORECAST, GA LIM, FUEL MGT and EO RANGE. FSS marks these pages as not implemented ^[24].
