reported Brake Accumulator won't be recharged with Emergency Landing Gear Extension selected and Hydraulic Isolation Override switch in ORIDE.

It's just a minor problem.

According to NFM-000 (2.7.3 Valves, 2.7.4 Accumulators,Figure 2-11. Hydraulic System)

If the APU Arming Valve is opened together with the Hydraulic Isolation Override switch in ORIDE,the Brake Accumulator should be charged by HYD 2B circuit.

And the APU Arming Valve will open when either:

(1).Emergency Landing Gear Extension is selected

(2)Emergency IFR Probe Extension is selected

(3)Weight on Wheel is sensed.

Hence,the brake accumulator can be charged in flight by circuit 2B if the HYD ISO switch is in ORIDE and either Emergency Landing Gear or Emergency IFR Probe extension is selected.

 

In the sim now,it seems that the APU Arming Valve will only open when :

(2)Emergency IFR Probe Extension is selected

(3)WOW

But won't open when :

(1)Emergency Landing Gear Extension is selected.

 

As a result,the brake accumulator won't be recharged in the sim with Emergency Landing Gear Extension selected and Hydraulic Isolation Override switch in ORIDE.

 

Here is the track:

Brake Accumulator won't be recharged with Emergency Landing Gear Extension selected and Hydraulic Isolation Override switch in ORIDE. .trk

 

Thank you for your hard work.
