At AWAC we departed out of DCA RWY 01 about four times a day and we would engage NAV mode at gear rotation whether using the National Five (using the VOR) or subsequently the RNAV procedures now in use.
BUT, as always, policy is policy so if it says wear out your finger pushing extra buttons, do it.
Let’s keep this simple - at the positive rate callout. PF calls gear up Speed mode and or HDG/NAV mode as required. Autopilot comes on at 600ft for T.O. No memo has ever existed for AP use on T.O. Below 600ft for the CRJ900 under Endeavor operations.
Capiche?
Again
Example
P.F. Gear up, Speed mode, Heading mode.
Example 2
P.F. Gear up, Speed mode, NAV mode.
Cool? Cool.
