Reducing airspeed during curved departure with engine failure
The following paragraph in an airline B737NG Operations Manual has me wondering. It refers to an engine failure requiring a curved departure.
"The radius of turn will be based on TAS (IAS V2, corrected for an airport reference temperature and airport elevation +500 ft). In some cases, different temperature and speed may be considered. The flight director pitch bar will command V2 to V2+20 knots depending on what speed the engine failure occurred at. Consequently it may be necessary to look ‘through’ the Flight Director pitch bar to ensure V2 is flown during the turn."
My understanding is that the FD pitch bar commands the speed at which the engine failure occurred; not exceeding V2 plus 20 knots and that you do not deliberately pull the nose up or reduce power in order to reduce the speed back to V2 during the turn - or at any other time with engine failure on take off. You should not have to "look through" a FD since Boeing state if the FD is not giving you the information you want, you should switch it off.
