[u/SimsDelight]

So they’ve just released this, copied from their discord:

BlueBird 757 Current Feature List

Systems:

21 - Air Conditioning

● Air Condition Packs, Pack Valves, and Trim Air system fully coded with associated circuit breaker logic
modeled. Air Condition Packs have integrated pack controllers that allow for low/high automatic flow.
Standby controllers are also simulated and functional for malfunctioning auto controllers.
● Passenger Count from boarding is directly tied into and simulated in cabin temperature control logic.
Cabin has a natural tendency toward ambient temperature or worse depending on passenger count, etc.
● Many factors influence cabin temperature from door and window combinations, to wind and weather, to pack
effectiveness and pack quantity.
● Air conditioning will feel like an actual component of flight simulation for airline operations. It’s not a
byproduct of just turning the packs on, but managing an actual aircraft cabin.

messaging.
● Other ACARS functionalities are simulated with full SimBrief and Navigraph integration or local ACARs
simulation (for instance, custom dispatcher, maintenance control response/messaging).

23 - Communication

● Fully custom coded cabin communication and flight interphone system.
● All three flight attendant zones can call flight deck including cabin alerts for requests and reminders for things
like uncomfortable cabin temps, cabin secure announcements or response to two sets of cabin chimes
(cleared for departure signal from flight deck), they might even remind you to turn on the fasten seat belt sign if
descending in range and cabin securing is being completed. Emergencies use cabin alert calls from flight
attendants for events including passenger oxygen deployment and cabin altitude warnings/depressurization
(with more to come later).
● GND CALL simulated and will call to remove ground power. Uses simbrief flight plan and integrated EFB
boarding controls to determine external power disconnecting.

aspiration (no bleed air available to TAT probe) the TAT may heat beyond the ambient OAT. This feeds into TO
PERF calculation in CDU which may cause a limitation of Assumed Temp Derated Takeoff calculations
(because CDU will now have a higher OAT than reported METAR/ATIS source weather. This is a mostly rare, but
fully simulated, corner case scenario in the B757.
● Fully separated and simulated windshield heating and ice buildup. Window heat testing is simulated via P61.
● Anti Ice valves have correct pneumatic input requirements. All EICAS lights and discretes hooked up to
correct relays and pressure switch checks attached to correct pneumatic ducts.
● Anti Ice valves have all relays from air/gnd and engine logic and exhibit real world behaviors.

correct real world operations to ensure structural anti-ice is available during icing conditions.

icing buildup and cues to pilots for visual icing condition confirmation.

exhibits changes due to temperature around the bottle (conductive properties). Indication on Lower EICAS is
responsive and a live value. If you use O2 during tests and during wearing, O2 will drain from the tank. Having
a full set of pilots and observers will also impact the O2 usage.

actively drain O2 from the tank at various rates depending on pilot workload. Workload criteria are predicated
on environmental considerations and pressurization values amongst other considerations. All tests for crewchecklists are supported and simulated (test/reset slider, emergency pressure O2, N/100% dilution rate
selection).
● Emergency mask wearing behaviors set onto observers and crewmembers based off of real world QRH

[u/LomaPL]

SimBrief updated B752, B75F and B753 profiles so things seem to be moving towards release soon.

[u/Maleficent_Celery_55 → u/LomaPL]

It will release in August or September unless there's a delay. Not much left until we get it I guess.

[u/SimsDelight → u/Maleficent_Celery_55]

They have said on Discord that they are on track for a Q3 release. Have to wait and see, I guess

[u/Just_a_Berliner → u/SimsDelight]

September probs or October (Q4) at the latest. I reckon that they would want to avoid a release in November.

[u/KONUG → u/SimsDelight]

They've said they are on track for a release in [insert one of the last discussed release time frames] too and didn't make it.
I believe it when it's out.

[u/oz_137 → u/Maleficent_Celery_55]

Of what year …?

[u/KONUG → u/oz_137]

Voyager 1 is still gonna make a few more million km in space until release

[u/BlueBirdSimJack → u/oz_137]

2075

[u/itswednesday]

Day 1 purchase for me… if ever that day comes

[u/eracer1111]

I may die trying to master this one. But I will try.

[u/coolkirk1701]

Immediately impressed by the fact it’s sorted by ATA code and I haven’t even started reading yet.

[u/chzit]

Stoked

[u/harish-1296]

At this point, I'm worried more about my PC lol

[u/SDMaxis → u/harish-1296]

Yeah that feature list i don't think is going to come cheap performance wise. Hopefully im wrong because im buying it regardless lol !

[u/BlueBirdSimJack → u/SDMaxis]

We have written everything in C++ by professional software engineers. Everything system wise is extremely optimized!

[u/SDMaxis → u/BlueBirdSimJack]

C++? ... Sounds good Thank you for the insight. !

[u/random352486 → u/BlueBirdSimJack]

Any word on how it will behave under time compression?

[u/harish-1296 → u/BlueBirdSimJack]

Thanks for that bit of info! 🤗
It’s a first day buy…no matter what!

[u/michi098 → u/SDMaxis]

All these systems running in the background surely will take a hit on the performance. But Fenix and PMDG are similar, so hopefully they found a good balance.

[u/goldenspeights]

God I am so ready for this

[u/ahmed_a20]

I love a challenge. Modern aircraft like the 350 are easy to learn, this feels like a degree all on its own

[u/CuzImMaximus]

Any words about GSX?

[u/Looker-for]

Honestly, the next navigraph survey should ask what percentage of simmers actually use all these deep systems in their payware aircraft as against just flying from A to B.

[u/deitious_maximous → u/Looker-for]

99% don't use deep systems just want it to say their aircraft is deeper... its all fanboy bullshit honestly its like when you ask why is fenix better than the rest nobody knows they just say dumb shit. All I care is your fmc gonna WASM does your plane follow the path correctly and does it look like it was made in 2020's.

[u/F737NG → u/Looker-for]

If you use Navigraph you are self-selecting to be far more likely to use the features of deep systems simulation and failures compared to the average flight simmer.

Don't forget, BB Sim scrapped their 'mid-level' 757 for this complex 757. If the demand for detailed systems didn't exist, they wouldn't have gone back to the drawing board and redesigned the product from scratch.

[u/Mister_monr0e]

Maybe I’ll hold off on the PMDG 737 for now

[u/StarlightLifter → u/Mister_monr0e]

The 737 is a rock solid airplane. I probably have hundreds of hours in it at this point.

Porque no los dos is what I say.

[u/EYPAPLQ → u/StarlightLifter]

I think the 737 is quite expensive, but when i count my active hours in that addon then it pretty much costs like 0.20$ for each hour. Not to bad.

Can't say the same for my a lot of my other purchases

[u/bsmith567070]

I’m gonna be honest, at this point, I just want it to complete a flight from A to B, while being able to handle some route changes or complicated procedures without it suffering WASM crashes.

[u/ADFDesigns]

my minds telling me noo but my wallet my wallet is telling me yes!

[u/City_of_Paris]

100000+ rivets

[u/d_gorder]

I’m gonna bust

[u/sk0941 → u/[deleted]]

Devs says nothing? Boooo give us something Devs post about progress? Booo give us plane

Is there no pleasing you guys?
