Yoke operations after loss of all engines
#11
I will chime in on the "everything is aircraft specific" bandwagon.
Some quite large aircraft (such as the DC-8) were designed without hydraulic power to some or all of the flight controls. This can work because control tabs are used to aerodynamically reduce the force required. The DC-8 elevator was strictly muscle powered via a very long and thick cable. The majority of pilots used two hands to flare. The horizontal stabilizer (trim) did use hydraulics, with electric backup trim.
