Specification of this question:
It refers to Boeing's FCOM Automatic Flight Chapter 4 System Description Section 20 (4.20.3)Flight Director Display
Turning a F/D switch ON displays command bars on the respective pilot’s attitude indicator if command pitch and roll modes are engaged. If command pitch and roll modes are not engaged, the F/D command bars do not appear. The F/Ds can be operated with or without the A/P and A/T. F/D command modes can be used with an A/P engaged in CWS. F/D commands operate in the same command modes as the A/P except:
• the takeoff mode is a F/D only mode
• dual F/D guidance is available for single engine operation
• the F/D has no landing flare capability. F/D command bars retract from
view at approximately 50 feet RA on an ILS approach. Normally, FCC A drives the captain’s command bars and FCC B drives the first officer’s command bars. With both F/D switches ON, the logic for both pilots’ F/D modes is controlled by the master FCC, and both FMA displays show the same mode status. The master FCC is indicated by illumination of the respective master (MA) F/D indicator light. The master FCC is determined as follows:
• with neither A/P engaged in CMD, the FCC for the first F/D turned on is the master
• with one or both A/Ps engaged in CMD, the FCC for the first A/P in CMD is the master FCC, regardless of which F/D is turned on first.
Does the sequence of activation of CMD A and B comply with the description in this chapter?
