Why complicate things so much when you have plenty of speed, terrain clearence and situational awareness? Why does a GA have to be so dramatic?
- Gear up, flps 15,
- Just retune the VHF nav1 and 2 to your MAP VOR to exit approach-mode,
- tap some on the mcp (I would go with LNAV and a low VS rate or VOR/LOC + VS) Or even heading select + VS,
- verify the FMA so that the aircraft is commanded to do what you want,
- clean up the aircraft on schedule while descending and have the girls bring you a coffee as you hold
Piece of cake
I wouldn't press TOGA and disengage the AP and put the pilot monitoring into big work load with everything coming at the same time (rt, monitoring me, configuring a/c, callouts, tuning navaids, CDU entries, transition alts, altitude remaining callouts etc) as I'm having a 15 degree pitch up with a feather light plane when I should be descending instead within the congested TMA
