HEY!
I was wondering how you service the flight control actuators. As I understand they are electricly powered, but have an internal hydraulic system. How often do you check for leaks and oil level?

| Just a guess here but hydraulics are something you check before and after each flight on the 16, so it would be the same on the 35. And you would service them when the need it. |

Well, the F-35's flight control (like the Boeing 787's) is localized. That is there is no central hydraulic reservoir and pump with fluids carried in lines. Instead, each actuator has an electric pump and its own tiny reservoir. The only connections are electrical. This has a few advantages. The first being that it is a lot easier to provide multiple pathways and redundancy for electrics than it is to run multiple redundant fluid lines with complex valving to localize failures or damage. The second is that during servicing, everything is localized and can hence be replaced or worked on without affecting or involving everything else. The F-35 is the most "self-diagnostic" aircraft ever, so I presume that each actuator has sensors to tell the ground crew and the pilot if pressure is good and fluid levels are right. |

| They hook a computer(s) up to the F-35s computer(s) so the F-35 can tell them where maintenance is required... cool! It's like KITT from knightrider! |

Failed/degraded flight control surface indicators are displayed on the instrument panel/screen in real time during flight. |
