Regarding looking after your hydraulics, if you do so, they may look after you. Years ago, when I was flying the Boeing 737 Classic 300 series, we had hydraulic system “A” fail (the contents emptied somewhere over Lyon). That resulted in Autopilot A failed, Thrust reverser Eng 1 failed, Gear: Emergency (Gravity) lowering, “A” system Spoilers failed, NWS failed.
We continued to Nice, in accordance with the QRH you can do so. On final approach to 04L we experienced what I presume was asymmetric up float of the failed Spoiler(s), because when speed reduced the control yoke needed to be moved further and further to the right. We touched down on 04R (having been refused 04L by the Tower) with the control yoke at an angle of 90 degrees i.e. 6 o’clock position. Aileron trimming made no difference.
So, look after the strain on your hydraulics and they may look after you!
