For the B787 just follow the pitch targets in the HUD. It will adjust for an engine out situation.
Following the FD, without looking through it. Hence the question, is there a target pitch… |

Unfortunately, no examples provided from manufacturers manuals, other than a standard target pitch that is always the same, not calculated.
Which makes me suspect that this is a company initiated policy. We currently use the Boeing OPT iPad app for our performance figures on the 787-9 and apart from V speeds and flap settings, all engine and engine out target pitch attitudes are calculated. We do rotate TOWARDS 15 degrees, but will end up at the calculated attitude on speed if our rotation rate was correct. |

We also follow the magenta line, after the route is checked, not blindly. |
Interesting. I am maybe forgetting now, but I don't recall this on any conventional type I have flown - even the B737 Classic. It was always a set pitch. Those aircraft were not the size of a B747 though.
Airbus FBW presumably does use the aircraft mass to calculate a pitch angle for the speed bug and the SRS, speed reference system, to achieve V2+10? But it does not display it as an actual figure for the pilots, who rotate to +15° and when airborne they follow the SRS in pitch. |
