Problem with flaps in the landing tutorial

[jfri]

The flaps fail to extend sometimes before landing and sometimes after. I could solve this by applying the manual hydraulic pump but I don't understand why I should have to. The hydraulic meter always shows the pressure in the green area.

You have a track?

Not yet but I do have information. This is a tutorial and I don't make any changes in the plane except when I am told to. Gear always extends. Then when I move my assigned switch for the flaps I see the flap handle move as intended in the cockpit. Also see hydraulic pressure in the green. In both cases it helped with the hydraulic hand pump for some times.

Make sure that you dont deploy flaps and landing gear at the same time, also after you lower flaps put handle in neutral, if not when you pull landing gear handle flaps will retract due to pressure loss. I didn't encounter any problems with flaps when operated properly
