The Impact of Lowering the LDG and Flaps/Slats In Standby???
In the drills regarding the LOSS of hydraulic systems (737-300/500) there is two notes.
-Note: When the gear has been lowered manually, it cannot be retracted. The drag penalty with gear extended may make it impossible to reach an alternate field.(This note is related to the loss of system A)
-Note: The drag penalty with leading edge devices extended may make it impossible to reach an alternate field. (This note is related to the loss of system B and the flaps/slats are extended by standby pressure)
How serious the fact that extending the gears and the leading edges devices will affect the fuel reserve?
Did this problem (fuel depletion) happen before?
Does it mean, it is preferable (may be recommended?) to delay the extention of the gears (manually) and the flaps/slats (standby mode)? How pilots overcome this problem?
Can other aircraft (Boeing & Airbus) encounter this problem?
Thank you. Feedback appreciated
Best regards
