BUG - Apu continues to operate even after you have finished fuel

[thiengo]

I turned the APU on and consume all the fuel from the aircraft, it remained in operation.

The same occurs when to start them with fuel tank dry.

I would also emphasize the amount of fuel not consumed, it is understood that the operation of engines and the APU should be stopped when the fuel pump is not able to put fuel. operation does not end with zero fuel but with the remaining unused.

is a great pleasure to meeting you again, i am flying the big boy to do then better.

Data to share

Collector Tanks

Two collector tanks are located in the forward section of the center wing tank. Fuel

from each wing tank is fed under pressure to its respective collector tank by scavenge

ejectors. The collector tank capacity is 10 gallons (38 liters) and when the tank is full,

excess fuel is vented back to the respective wing tank. Fuel can also be fed from the

wing tanks to the associated collector tank by gravity. There is no migration of fuel from

the center tank into the collector tanks. A main fuel ejector in each collector tank is

immersed in fuel and is used to ensure a positive supply of fuel to the engines. The

boost pumps normally supply fuel to the engines for start.

During climb, fuel could enter the center tank from the

vent system. This fuel can cause erroneous center

tank quantity indications as high as 300 lbs (135kg).

Fuel tank capacities for pressure fueling operation:

TANK USABLE FUEL UNUSABLE FUEL TOTAL FUEL

Left Wing 4760 lb (2159 kg) 20.4 lb (9.2 kg) 4780.4 lb (2168.2 kg)

Right Wing 4760 lb (2159 kg) 20.4 lb (9.2 kg) 4780.4 lb (2168.2 kg)

Center 4998 lb (2267 kg) 6.8 lb (3 kg) 5004.8 lb (2270 kg)

Total 14518 lb (6585.2 kg) 47.6 lb (21.6 kg) 14565 lb (6606.8 kg)

Fuel tank capacities for gravity fueling operation:

TANK USABLE FUEL UNUSABLE FUEL TOTAL FUEL

Left Wing 4488 lb (2036 kg) 20.4 lb (9.2 kg) 4508.4 lb (2145.2 kg)

Right Wing 4488 lb (2036 kg) 20.4 lb (9.2 kg) 4508.4 lb (2145.2 kg)

Center 4930 lb (2236 kg) 6.8 lb (3 kg) 4936.8 lb (2239 kg)

Total 13906 lb (6308 kg) 47.6 lb (21.6 kg) 13953.6 lb (6329 kg)

The APU doesn't use fuel - is this to prevent the CRJ from breaking the FSEconomy plugin? I don't have either (yet!) but I've heard that tampering with your fuel in-flight, whether that's through the Aircraft/Weights and Fuel menu or directly with a plugin, causes FSE to reject your flight.

[woweezowee]

No. Nothing to do with FSE.

Have to take a look at this one.

How dont APU use fuel? Do you mean that apu dont use fuel in CRJ200 Jrollon projetc?

apu is a engine like other one.

the APU is a fully automated gas turbine power plant

The maximum operating altitude of the APU is 37,000 feet. The maximum altitude for APU

starting is 30,000 feet. The maximum altitude for main engine starting using APU bleed air

is 13,000 feet. ECS operation using APU bleed air is 15,000 feet.

Fuel is supplied to the APU fuel control unit from the left and right wing tanks by the

XFLOW/APU pump (refer to Chapter 13). The fuel shutoff valve is opened by the ECU

at 10% speed. The fuel control unit starts, stops and modulates the flow of fuel to the

APU in response to commands from the ECU.

This information was taken from Flight Operatio Manual, Chapter Systems - Auxiliary Power Unit.

Sorry Thiengo I wasn't clear! My English was bad... When I said "the APU doesn't use fuel" I should have said "If the CRJ's APU isn't using Fuel in X-Plane, then perhaps it's because of...".

No problem, my english is bad too.

i guess the Jrollon will see the problem when possible. Was what i understood.

Realy the plane is burning fuel until zero. at least, the engines are starting up and running only with fuel in tanks... but APU is starting  and running without fuel.

Another point interesting to consider is, the tank right and left with 450lbs of fuel in each continuing burning (And must to do) but the burn in this critical level must operate with restriction in pitch angle, dont exceed 10° of pitch in climb... risk to shutoff the engines.

Is this correct Elber? (If you are reading this post )

in the future, the project could consider this variable to operate, simulating the unusable fuel remaing, and the critical tank level in high pitch angle.

and the fuel port switch action could show the messagens for APU IN BITE diagnostic... and, APU SOV CLSD, APU START, APU LCV OPEN...

Is FSEconomy a addon to simulate a company, like the other in Microsoft Flight Simulator 2004/X?

Hi thiengo,

it is a "economic environment". At first, you are a pilot only. You can rent planes, fly assignments, make money. But you also can join groups, build on airports, buy and sell stuff, your planes will need repairs, and much much more.

you can read more about it in the manual:

Very nice, can this plugin be operated by a remote computer. i am a home builder cockpit and the only interface that i use with x-plane is the hardware that i develop and instructor pc.

I did like  the video, nice scenery, in Brazil dont have scenery lovely constructed pra xplane, i fly default xplane scenery..

[woweezowee]

not sure about that. It is a python plugin and needs that Sandys Python Interface is installed, too - both inside xplanes plugins folder.

Maybe just try if you are interested. It is all free:
