Hi all, I've just started flying the Saab and I've hit on a slightly confusing behaviour from the hydraulics, which doesn't seem to have an obvious answer (at least based on my reading of the Systems manual). For my first few flights, the hydraulics pump would activate for a couple of seconds every few minutes and then switch off, this was irrespective of phase of flight or config, as long as I had started up it kept happening. No warning lights were showing, and it didn't seem to have any effect, so I put it down to a quirk of the type (never having flown a real one). On my last flight, it seemed that after startup, the hydraulics pump activated continually, again, irrespective of flap or gear actuation. If I used the Hydraulic Pump switch and moved it to OVRD then back to AUTO, it would turn off, only to re-activate a minute or so later. I was additionally getting Low Hyd Pressure warnings on the panel. The only thing I could see that didn't look like the previous flights was that the Hyd Fluid quantity was slightly lower, but still in the middle of the green arc. From the Systems Manual, the only things simulated that should influence this are wheel brakes, gear & flap actuation and the pump switch, but I've been following the checklists and given for the bulk of the flight the pump was on auto, gear was up, flaps were up and wheel brakes were off, I'm rather stumped as to what could be causing this. Any thoughts? Cheers, Jamie
