Looking at the original post, LVL change versus TOGA at 1000 AGL here we go.. TOGA is a Trust mode that will provide aircraft acceleration and allow flap retraction on schedule, also commands Ground Track and a Known pitch angle 15 degrees, generally recommended according to the FCTM and unless you have a TOGA switch failure is a sure way to climb away.. on the other hand a may not be required in all circumstances. On the other hand, LVL change is a pitch mode that according to the MCP speed will pitch up ( or down) if the target speed is not on schedule, no acceleration is provided without increasing MCP speed and pitch can be erratic. If the autopilot is engaged with no auto thrust additional issues could occur. As observed, at 1000 AGL with APP engaged a de tune of the ILS is required to come out of APP and allow LVL Change to engage, track will be HDG selected at the time.On balance, the workload required is higher when using non-standard go-around procedures. Without APP engaged LVL change of VS with auto throttle can be a smoother event.
