I have not checked if Leonardo modeled this, but running L and R systems off just the AUX pump will result in sluggish performance from the user systems. And if you try to run 2 things at once... like gear and flaps... they will run very slowly. This is because the aux pump cannot supply the GPM demand at sufficient pressure.
Hi Michael, interesting. So dven with the same hydraulic pressure on both sides (3000 psi) the response becomes sluggish? Can you throw more light on why that happens? What is gpm demand? Thanks a lot for commenting and giving your insights :)
@@AirborneGeek pump pressure is a function of flow rate. As flow rate increases, pressure decreases. At lower pressures, hydraulic actuators lose performance and become slow. The AUX pump can supply 8gpm @ 2200psi or 6gpm @ 2750psi. The flaps require about 10gpm and the gear is probably about the same (I cannot find any documentation on that). So if you ran both at the same time, the AUX pump will have fallen way down the pump curve. Here's a generic example of a centrifugal hyd pump curve. Google hydraulic pump curve to see an example.

Makes perfect sense. Thanks!!
These videos are amazing. Would love to see more of them on the Maddog!
Thanks a lot Sandro 😊 Really hard to find an audience on these but I'm glad you enjoy these 😃
The link to Discord doesnt work. Can you give me another link?

When should high or low mode on eng hyd pumps?
I have completely forgotten how to use this airplane 😅
