After many lessons learned from building the RA80 MAX Cargo, this next airliner will feature an older design concept, similar to a B727 or Fokker F21. This time, the systems are far more detailed, and the cockpit is entirely original. This will be mod-free, and able to run smoothly on a Meta Quest 2 with a part count between 1,000 and 1,100.

This design is named the RA40 Excelsior, a 70,000 LBS, short-haul turboprop. Equipped with a set of airstairs, she is ideal for island hopping and can service any of the airports in SimplePlanes. There will also be a rudimentary landing assist for Wright Airport, based off a simple longitude and latitude coordination. This will enable a pretty precise approach and stabilized landing using various cockpit instruments.

Electrics
The electrics of this craft is powered from three 110 K VA IDGs (Integrated Drive Generators) and one exterior power connector. These energize the left and right AC systems, which further (thru rectifiers) energize two respective 28 V DC systems. The biggest issue I ran into was making circuit breakers: that being I have not been able to get the buttons or switches to physically toggle without being pressed. So I cheated and made sure was impossible to overdraw the system thru various means.

Fuel
Only two tanks for this craft. I made this system capable of fuel transfer as well. I determined the mass of SimplePlanes jet fuel as 6.685 LBS per gallon, so the fuel reads in tons and the fuel flow in tons per hour.

Hydraulic
A left and a right system at 1,500 - 3,000 PSI, each powered from a respective engine drive pump and AC motor pump. This is based closely off a Dash-8.

Pneumatic
This one is quite simple. The two engines and APU bleed into the ducts, powering two fuel pumps, the engine starters and PACKs. Cabin pressurization has hit a road block for the moment.

Miscellaneous
The thrust/propulsion isn't exactly powered from the props. To make the blade pitch management be not such a chore, I had to make their actual power quite weak. The useful thrust is from the turbojets (used for exhaust and noise effects).

Not too sure how much longer this one will take to be complete, but hopefully won't be too far into the future.
