see. off-topic at the bottom of the desc.

Please watch this tutorial
IMPORTANT NOTES:

1.) Erratic manual flying might lead to bugs in the fly by wire. This plane was intended for typical airliner flights.

2.) The "Flight Augmentation Computers" switch needs to be turned on to operate in normal law, I forgot to put this in the instructions.

3.) For more stable flying, avoid deploying flaps or spoilers while the autopilot controls the ALTITUDE, particularly when it is CLIMBING. (Spoilers will deploy automatically under the right conditions)

4.) Each engine takes 1 minute to idle/self sustain (If the corresponding fuel pumps are active), unlike the NJ-100 which took 30 seconds. Please be patient. You may also look at the N1 indicators, they usually Idle at just below 25% N1 (Again, it is important to have the fuel pumps on to reach idle or you'll just Motor/Spin at 14% N1)
BTW: The N2 indicators are just below the N1 indicators. If you know what they do in real life, it shouldn't be hard spotting them.

Anyways, just follow the checklist (In the Instructions) and watch the tutorial, then it should be fine! :D

Overview

The NAA NJ-150 (Originally the NJ-120) is a next-generation narrow-body airliner developed by Noble Aerospace Agency’s commercial branch, with advanced modern efficiency and automation. Drawing direct inspiration from the Airbus A321XLR and Boeing 737NG. the NJ-150 represents NAA’s bold vision of integrating cutting-edge materials and avionics.

Design

The NJ-150’s design was guided by three principles:
Simplicity in Maintenance– echoing the A321’s reputation for easy servicing.
Efficiency in Operation– matching the 737’s balance of performance and economy.
Automation– Advanced fly by wire technology, makes flying 10x safer and easier

History

The NJ-150 first entered service with British Airways in October of 2028 on routes between Krakabloa, Xinshan Island, and Wright. Early operators praised its short-field performance and surprisingly low maintenance turnaround.

Public Reception

The NJ-150’s blend of classic and modern aesthetics sparked massive interest at the 2027 Paris Air Show, where it was nicknamed the “Sleek Eagle.” Pilots transitioning from older fleets, like the NJ-100, praised its automatic handling, while passengers admired its aesthetic cabin and panoramic side windows.

Off topic:
As some of you already know by now, I recently started Engineering courses at my university and turns out It's a lot harder than High school (shocker), which is to be expected, honestly. I initially thought I'd be able to juggle everything and still have time to build cool stuff in SimplePlanes but unfortunately, that doesn't seem to be the case. I've already had close calls with some of my grades (and that's a lot scarier than you think, in my case atleast) so I've made the decision to take a small break from SP and a lot of other apps as they're pretty distracting. I wouldn't want to screw over all it took to get here. Like I said, school isn't really as easy anymore and I need to turn off a lot of things to maintain a good GPA while touching grass and meeting new people.

Anyways, making the NJ-100 and NJ-150 was an absolute blast, I'll tell you that. I never thought I'd do full on startup sequences and fly by wire systems but here we are, I've learned so much in FT. I'm happy I've gotten to this point in SP, really.

Thanks to all of you lovelies, we will meet again, in SimplePlanes 2.
okthxbye!
