A319 Advanced Beta (PC & Andriod)

After completing a bunch of Ultra Longhauls, I've pretty much added everything I can to the A350, am now waiting for the Beta to be over so I can test it on the live build.

In the meantime, I decided to test how quickly I could apply everything to another aircraft. The result is an A319 Advanced, with a mobile version that will need testing in the next week or so (Android). The stock Aircraft is already quite detailed, so it was much easier than the A350, for example direct law and alternate law is already built in.

Like with the PC version, I'd need just two beta testers for now (preferably older than 18 years old) and with an understanding of Airbus systems. PM if interested.

A319 will be slightly stripped back on mobile since there is no dll or ability to run external programs for RAAS/High level failures/Black Box, ATC, or real-world visibility and runway braking conditions. Full features listed below -

It fixes most of the A3xx bugs in the live and beta builds, but I'll likely have to adjust as the devs fix the issues themselves. This was built using the real-world FCOM/FCTM and QRH.

I'll post features below -

Aerofly FS4 – A319 Advanced Beta

The A319 Advanced project expands the stock Aerofly FS4 A319 with a much deeper systems simulation while retaining the native aircraft, displays, flight model and Airbus A320-family architecture.

Full list and Stock bug fixes in the PDF attached -

Below are the basics..

FUEL SYSTEM

• Physical engine fuel consumption from the aircraft fuel tanks.
• Corrected centre-tank-first fuel feeding when the centre pumps are operating.
• Automatic transition to the wing tanks as centre fuel is depleted.
• Independent left/right engine fuel-feed availability.
• Engine starvation is tied to actual usable fuel/feed availability rather than simply total fuel onboard.
• Engine fuel consumption calibrated from the actual engine fuel-metering demand.
• Physical APU fuel consumption.
• APU draws fuel from the left wing system through its normal fuel pump/LP-valve logic.
• APU fuel consumption stops when a usable fuel supply is no longer available.
• Corrected wing low-level fuel sensing.
• Dual wing low-level condition can produce the appropriate LAND ASAP consequence.
• Improved FUEL ECAM actions where supported by the existing controls.

AUTOMATIC MCDU REFUELLING

The native Airbus INIT B page is used for refuelling.

The normal fields remain:

• TAXI
• ZFW/ZFWCG
• BLOCK
• TRIP/TIME

Entering a BLOCK fuel value greater than the current FOB can physically refuel the aircraft.

Refuelling requires:

• Aircraft on the ground.
• Aircraft stationary.
• Parking brake set.
• Engines shut down.

The APU may remain running.

Features include:

• Approximately 16.35 kg/s total simulated pressure-refuelling flow.
• Symmetrical wing filling for lower fuel targets.
• Centre-tank filling when the required BLOCK exceeds wing capacity.
• Automatic stopping when the selected BLOCK quantity is reached.
• Native REFUELG indication while fuel is physically flowing.
• Ability to enter a higher BLOCK value later to start another refuel cycle.
• Approximately 19 tonnes maximum modelled usable fuel.

The native FMGC TRIP fuel prediction remains untouched in the current beta because experimental modifications caused MCDU prediction regressions.

HYDRAULICS

Expanded Green, Blue and Yellow hydraulic-system consequences.

Hydraulic failures can now affect the systems that actually depend upon them, including:

• Landing gear.
• Slats.
• Flaps.
• Spoilers.
• Reversers.
• Braking.
• Nose-wheel steering.
• Yaw damping.
• Landing-distance procedure/status consequences.

Single hydraulic-system failures now have more realistic ECAM STATUS and INOP consequences rather than simply producing a warning message.

BRAKING SYSTEM

The braking architecture has been substantially rebuilt.

Normal braking

• Uses Green hydraulic pressure.
• Requires the appropriate BSCU/anti-skid architecture.

Alternate braking with anti-skid

• Uses the Yellow hydraulic system.
• Retains full alternate braking authority while Yellow pressure and anti-skid are available.

Alternate braking without anti-skid

• Automatically limited to approximately 1000 PSI.

Accumulator-only braking

• Approximately 1000 PSI maximum.
• Real stored-energy accumulator model.
• Brake applications physically consume accumulator energy.
• Holding the toe brakes continues consuming stored pressure.
• Yellow hydraulic pressure recharges the accumulator.
• Brake authority gradually reduces as the accumulator is depleted.
• Accumulator pressure indication follows the actual stored energy.

The model targets at least several full brake applications from a charged accumulator.

Parking-brake pressure is also connected to the Yellow/accumulator architecture.

BSCU / ANTI-SKID

• Independent BSCU channel redundancy.
• A single BSCU-channel failure no longer incorrectly removes anti-skid.
• Both channels must be unavailable before the appropriate total-loss consequences occur.
• Existing anti-skid ECAM logic integrated with the advanced braking architecture.

LIVE RUNWAY BRAKING CONDITIONS

The Advanced braking model can accept an external runway-condition factor.

Current approximate calibration:

• Dry – 1.00
• Wet – 0.81
• Heavy rain – 0.65
• Slush / standing water – 0.42
• Ice / freezing rain – 0.35
• Severe wet ice – 0.20

This is applied at the physical tyre/runway braking stage rather than by faking hydraulic pressure.

BRAKE TEMPERATURE

• Independent brake thermal states.
• Existing physical brake-energy model retained.
• Brake-fan cooling model.
• Brake fans only provide effective cooling with the landing gear in the appropriate configuration.
• BRAKES HOT latches above approximately 300°C.
• Clears again below approximately 290°C.
• Thermal behaviour persists after heavy braking rather than immediately returning to normal.

Nice man! Any plans to do the A320ceo next?

Il’l have a go at this and test it out, I’ll let you know if I find anything (a320 type rated)

Btw, any chance you could look into implement holding in the MCDU? 🤔

The rest of the Airbus fleet is being worked on. I am limited to what I can access inside the MCDU, most of it is compiled. Am sure the Devs plan to add a Hold function at some point. The Direct-TO function is working well in the Beta.

Thanks to everyone who volunteered to test for Mobile. This is a little vid from the PC version. Since the A319 has pretty much all I need (I don't want to make it too complex, until Android testers report back on performance) I decided to work on the A320 NEO, since I enjoy hunting for real-world data. The CEO should be easier, since I have all the real-world data for that aircraft.

Basic video, just demonstrating the ground roll and nose thump sounds. Nose thump was a little tricky, as the sound is normally tied to nose wheel rotation (by default, the nose wheel realistically keeps spinning, even during gear retraction). The thump sound is now correctly tied to the nose wheel actually being on the ground. Little things like that take ages for an amateur like me. All working now, but still needs tweaking.

Importantly, and not shown in the video, I am extremely OCD about sounds; we should barely be able to hear the engines in cruise; it should be 99% wind hitting the windscreen. I've managed to nail it with the A319; I need to apply it to the A350 and A320 NEO/CEO, so you retain the powerful spool-up sounds in takeoff and climb; once reaching cruise, the engines are just a distant hum.

If anyone has access to the A320 NEO, QRH, or any maintenance manuals, please contact me via PM, and we can deal with it off the forum (please don't post a link here)

Full list of Current A320 NEO features below that will hopefully make it to Android. PC version will have full fidelity like the A350.

Bad news - I purchased an Android tablet and investigated the file structure. To cut to the chase, the Fuel system is very different from the PC version; I have nothing to modify. I don't even see a weight and balance menu

Everything else seems to work very well.

I was able to add the following systems to the A319, but I don't think it is worth pursuing until the devs eventually add their own fuel system; they stated they will likely do an overhaul at some point in the future. So we will have to be patient. I will focus on the PC version, but upload this version below to any testers who would like to try it.

Added and working

• Dynamic N1/N2 engine vibration — vibration now changes with engine speed rather than staying fixed.
• ELAC / SEC / FAC architecture retained and expanded.
• SEC spoiler ownership
  • SEC 3 → spoiler 2
  • SEC 1 → spoilers 3 and 4
  • SEC 2 → spoiler 5
• SEC pitch/THS backup — SEC 1 or SEC 2 can provide the standby pitch-trim path.
• FAC wiring corrections — fixed stock FAC1/FAC2 cross-wiring issues.
• Normal braking using the Green hydraulic system.
• Alternate braking using Yellow hydraulics when normal braking is unavailable.
• Alternate braking with anti-skid retains full braking authority.
• Alternate braking without anti-skid limited to about 1000 psi.
• Yellow brake accumulator now has usable stored pressure rather than effectively being unlimited.
• Accumulator-only emergency braking when Green and live Yellow pressure are unavailable.
• Accumulator depletion from repeated brake applications.
• About 7 full brake applications available from a fully charged accumulator.
• Braking gets weaker as accumulator pressure falls.
• Accumulator recharge when Yellow hydraulic pressure is restored.
• Parking brake uses Yellow/accumulator pressure and slowly drains the accumulator if no live Yellow pressure is available.
• Live ACCU pressure gauge rather than the original fixed Android indication.
• BSCU redundancy layer added; both channels currently healthy by default.
• Autobrake now depends on SEC availability — at least two SECs are required.
• If SEC availability is insufficient, autobrake drops out but manual braking remains available.
• All of this is using the Android-native A319 hydraulic/brake architecture

Could be added next

• Runway condition/braking effects — dry, wet, heavy rain, standing water/slush, ice etc.
• BSCU 1 / BSCU 2 failure faults and corresponding brake consequences.
• ELAC / SEC reboot timing — ELAC ~8 sec, SEC ~2 sec after switching back on.
• More detailed ELAC/SEC failure combinations and flight-control consequences.
• Engine oil temperature and more realistic oil behaviour.
• EGT reacting to pack/bleed load.
• Dynamic cockpit/cabin temperatures.
• Pack and bleed system faults.
• Crossbleed logic.
• Ground HP air cart feeding the actual pneumatic system.
• More realistic APU battery start and battery drain.
• Electrical/generator failures.
• GPS 1 / GPS 2 failures.
• GPS PRIMARY / GPS PRIMARY LOST.
• IRS drift and navigation accuracy degradation.
• DME/DME and VOR/DME position updating.
• ECAM/FWC messages for brakes, hydraulics, FCTL, engine, packs, nav, electrical etc.
• Fault overlays for training — hydraulics, brakes, FCTL, engines, electrical, navigation

Pleass where can i download the mod

This will only work for the A319 on Android. Check your PM in 30mins

Waiting for the current testers to report back, before I send to anyone else to test. The mod works on my Andriod device, but I need confirmation from them. If I get a green light, I'll add the sound mods and any extra advanced features from the PC version.

Something to point out, this doesn't touch any of the default aircraft files, it adds an overlay, I only own the A319 and A350, I dont plan on purchasing or modding any other aircraft for Andriod (unless I start charging for it) this cost me a few hundred pounds to buy a tablet and test this, and a good few days of man hours getting it to work. My Focus is PC going forward, since that is the platform I use.

Thanks

It will include all of the PC mods, so that will include the sound enhancements. Currently the only road block i encountered was the fuel system on android

Still waiting for Leroy999 to test I can't stress enough that I only want testers over 18 years old and those who are familiar with the A319. It wastes both our time if you only want a beta test copy for early access to play around..

Some good news this time. I added a lot of new functionality and fixed system logic in the A319 PC version. I also completed the sound pack. It all transferred to the Android version with no issues.

I will likely keep building the A319 on Android, just for academic purposes.

Included -

Sounds -

Ground roll and nose wheel thump

Electrical system sounds, and lowered HYD elec sound.

Engine sounds now react correctly to atmospheric density.

Many other small ambient additions

Numerous small fixes and typos in the current ELEC/Flight control and fuel system. I also managed to resolve a strange HYD blue overpressure issue that has been present on the stock A3xx

Still not as advanced as the current PC version, but I'll keep updating as time permits (in other words: I plan to work very slowly on Android)

Current working Android build: Electrical Stage 3A + GPU + Ground Air Cart

• FAC 1/2 reboot delay: 3 s

  
  

New in 12D:

• 1 Hz / 50% duty FAULT-light flashing
• ELAC FAULT should flash for about 8 s after switching back ON
• SEC FAULT should flash for about 2 s
• FAC FAULT should flash for about 3 s

• Then clear when the computer becomes available again

  
  

  Now that the nose wheel sound is confirmed working, I have blended the thumps into the overall mix.

I should also point out that the computing power is obviously not the same as a PC running an i9 and 5080, so I can't add the same amount of depth as the PC version.

Test flight - A319 Adv Emergency electrical config, power drops out once speed is no longer sufficient for the RAT.

DU corrected; EMER config should result in loss of lower ECAM, not the Captain's ND, as demonstrated in the vid. Use the switching panel to view the lower ECAM

Two days' work completed before I go on holiday (away for a week, then away for 7 weeks in October. This is PC only. I have someone testing the Android version tomorrow. This was built using Qatar's A319 maintenance manuals

• Pneumatics / Bleed
  • PACK 1 and PACK 2 overheat failures.
  • ENG 1 / ENG 2 bleed overpressure and overtemperature protection.
  • Engine pylon and bleed-air leak scenarios. (I've included a real-world bleed glitch in hot weather; hopefully the devs will add temps outside of ISA) Currently, the bleed glitch is dormant in the sim; in the real world, flaps should be left down when parked at (1+F) in very hot weather
  • Associated valve behaviour, ECAM cautions and STATUS consequences.
  • APU/engine bleed interactions retained rather than simply switching everything off when a fault appears.
• Cabin Pressurisation
  • CPC 1 or CPC 2 failure with automatic takeover by the remaining controller.
  • Dual CPC failure with genuine MAN mode operation.
  • Manual cabin vertical-speed control now physically drives the outflow valve.
  • Outflow valve stuck closed / not open failure.
  • Rapid-depressurisation scenario with realistic cabin-altitude rise.
  • Existing EXCESS CAB ALT and passenger-oxygen logic is exercised by the failure rather than being artificially triggered.
• Ground Handling
  • Reworked nose-wheel tiller response.
  • Much softer centre response for precise taxiing while retaining the full steering range at larger tiller inputs.
  • Pedal steering and high-speed steering reduction remain intact.

• Wing Fuel Pump Failures

  Various types of leaks are simulated: engine pylon, fuel tank

  • Individual left/right wing pump failures.
  • Dual pump failures on one wing.
  • Correct overhead FAULT indications, FUEL SD indications and ECAM procedures.
  • Remaining pumps continue to provide fuel where applicable.
  • Dual wing-pump failures now interact with crossfeed and gravity/suction feed, rather than being display-only failures.
• Centre Tank Pump Failures
  • Individual CTR TK PUMP 1 and PUMP 2 failures.
  • Corrected Pump 1 / Pump 2 cockpit and FUEL SD mapping.
  • A surviving centre pump can supply both engine feed rails when the crossfeed valve is opened.
  • Dual centre-pump failure now makes the centre-tank fuel genuinely unusable, as it cannot gravity-feed the engines.
  • Correct dual-pump ECAM logic without an inappropriate X FEED instruction.
• Fuel Crossfeed Valve
  • X FEED valve stuck open failure.
  • X FEED valve stuck closed failure.
  • Commanded and actual valve positions are monitored independently.
  • A failed valve now leaves the fuel system in its real physical configuration rather than simply changing an indication.
  • FUEL X FEED is correctly carried into STATUS when unavailable.
• Fuel Imbalance
  • Physical wing-tank imbalance modelling has now been added and is under test.
  • The ECAM procedure leads through the normal balance process: crossfeed open, centre pumps off where required, and pumps on the lighter side switched off.
  • With the crossfeed open, the heavier tank can then physically feed both engines, allowing the imbalance to be corrected rather than just displaying an advisory.
  • Dynamic fuel temps and realistic JetA1 Freeze temp (Fuel trends towards TAT)

TANK LEAK

PYLON LEAK

A350 is completed, I have enough testers now. I will release when the devs end the beta

Thanks
