In most aircraft with engines on pylons below wings engines will gravity feed when fuel pumps are off. Keep in mind that each engine also has it's own mechanically driven fuel pump.

-In sim ECON FLOW button seems to always reduce PACK flow regardless of conditions. It should however only reduce the pack flow in flight and only when both packs are operating according to FCOM. -CABIN FANS button should be present on the VENT panel, in sim it seems to be missing. -What about CARGO VALVE button on a vent panel? Haven't seen that one in FCOM, isn't it meant to be a thing only in a freighter variant? -Amber AUTO BRAKE light (above buttons to select autobrake braking strength) seems to be not working. It should flash for 10 seconds after autobrake is disarmed (except when autobrake is disarmed by pressing the button or selecting landing gear up). -Sometimes opening forward door creates multiple warnings. -Not a bug, but a feature request. What about adding exterior icing warning system (adding indicator light on anti ice panel)? That was optional equipment on A310.

Correction: I mean ESS TRU, not the ESS inverter.

More bugs found: -When aircraft is not under power (neither APU nor GPU available) and emergency lights switch is in DISARM passenger cabin lights are still on. -There is some invisible wall in passenger cabin making it hard to walk from cockpit to the cabin. -APU starter seems to be taking 300A of current from each battery, giving total current of 900A at 26V yelding insane 26 kilowatts of power (waaaaay too much for APU starter). -When aircraft is on battery power the batteries do not discharge, the ammeter shows 0 discharge current, even when running APU fuel pump. Only when APU starter is engaged they start to show discharge current. They should show a couple of amps, especially when running APU fuel pump. -ESS inverter shows slight current when aircraft is not under power (batteries OFF, no GPU nor APU available). Since there is no AC power to the aircraft inverters shouldn't show any current on the ammeter.

Testing latest version of A310 today. Still major bugs are present. -During cruise pressing right LSK on CDU always cause immediate descend instead of vertical revision. This is very major bug making you unable to make vertical revisions during cruise. -During PROFILE climb or descend pressing speed knob turns on PRE SET indicator, but AT and AP still follows the FMS speed instead of the manually preset speed. -During PROFILE cruise pressing speed knob does nothing (PRE SET indicator doesn't turn on and you cannot even input preselected speed). -PFD/ND XFER button does nothing.

Checked the FCOM. Seems like all fuel pumps (even the APU startup pump that runs through inverter when aircraft is on battery power) should be running from AC busses, only the contactors are meant to be powered from the DC bus. Seems like each pump consumes couple of amps from the TRUs, which is way too much for just a contactor (that should consume less than a single ampere). Another issue is with batteries. Even if I switch some batteries OFF they are still getting charged or discharged. Steps to reproduce the issue (to verify the battery disconnection bug): -Start aircraft in cold and dark state -Turn on only battery 2 and 3, do not turn on battery 1, also remember to do not turn on battery override switch -Switch the DC ammeter and voltmeter selector switch to battery 1 (to monitor battery 1 voltage and current) -Try starting the APU -When starter motor runs notice that battery 1 ammeter shows discharge current, even when battery 1 is isolated from the bus (OFF light on the button).

I'd like to report some bugs I have found in INI A310 (free version from marketplace). -First of all it seems like FMS speed override funtion is not working at all. When I am in profile mode and I press speed knob to enter FMS speed override the white light near the knob lights up and I am able to dial in the speed. The problem is that when I dial in the speed the autothrottle is still using the FMS speed and not the manually entered one. -Fuel pumps seems to be running on DC, not sure about A310, but in most aircraft fuel pumps run on AC (except APU fuel pump). I think that fuel pumps should be running on AC and do not increase TRU load when turned ON. -PFD/ND xfer switch seems to be not working. EGPWS terrain display on ND also seems to be not working for some reason.
