PIGPEN FBW

There are many excited changes in this airplane!

NEW TECHNOLOGY:

FAILURE SIMULATION

We have a failure simulation system.
At present, we have nine faults:
Airspeed(SPD) Data Lost
Altitude(ALT) Data Lost
Heading(HDG) Data Lost
Fly Path Vector(VEC) Data Lost
Attitude(ATT) Data Lost
GPWS Fault
Radar Fault
Engine Surge
Engine Fire
They are at the top of the variable list, like this:

If you don't want to trigger the faults, don't enter anything.
If you input an expression in the corresponding fault expression, and this expression is true under certain circumstances, then the fault will be triggered when the expression is true.
Among them, Engine Fire failure is irreversible, which means that once this failure is triggered, it will take effect permanently (because the failure column is only a trigger). However, this situation is an exception:
I have set the engine to surge several times before catching fire, with a default of 5 times. The engine will not catch fire if the number of surges is below the set value when the fault column expression for Engine Fire becomes false.


FLIGHT COMPUTER

The airplane uses a Flight Computer which works by a number of variables.
Features:
- Number input (will introduce later)
- Control the airplane by Auto Control System (or ACS)
- Interaction with the airplane
- Show some status of the airplane


ECAM&WARNING SYSTEM

Under the engine status show, there is a area which shows the airplane's status.
When something abnormal happened, a caution or warning message will show on the ECAM, with light on Reset Warnings' Button, blink on HUD.
There are some screenshots:



NUMBER INPUT

There is a keyboard near the Flight Computer, you can input something there.
To change a modifiable numeric input, press its corresponding button first, and the cursor will start flashing. At this point, all buttons on the flight computer, except for the keyboard, will be disabled.
Then, enter the number you want to set and click confirm. The system will calculate the corresponding number, and the words "Calculating..." will be displayed on the flight computer. After the calculation is completed (usually takes less than 0.1 seconds), the target content will be reset.
Let's watch a GIF.

("Calculating..." shows too shortly for the GIF to catch it)


GPWS

To avoid hitting the ground, we added GPWS System
(Note: it runs by a complex system, not only a timer)

ALTITUDE warning: GPWS detected that the airplane is going to reach the /minimum altitude above the ground of altitude warning/(70m, vertical direction, not straight-up direction, the same applies later) in 19 seconds, but [except the recovery time](the same applies later). Warning starts 2 seconds after meeting the conditions.

PULL UP warning: GPWS detected that the airplane is going to reach the /minimum altitude above the ground of pull up warning/(50m) in 10.5 seconds. Warning starts 2 seconds after meeting the conditions.
Pilots should take actions after triggering PULL UP warning.

CRIT ALT warning: GPWS detected that the airplane is going to reach the /minimum altitude above the ground of critical altitude warning/(5m) in 3 seconds. Warning starts 2 seconds after meeting the conditions.
Pilots should take actions immediately after triggering the CRIT ALT warning.
This warning means that if the recovery starts after 1 second, there is a high probability that it will not be able to be recovered and will hit the ground.

Warning prediction uses pure geometric methods and considers G-force protection mechanism. Without G-force protection, the system will assume that the pitch rate at the time of recovery is 20 degrees per second when ACRO is not activated


CONTROL CHARACTERISTICS & PROTECTIONS:

This airplane is capable of flying at high angles of attack.
Note: Due to aerodynamic layout issues, when the absolute value of the angle of attack is around 90 degrees, it will lose control over pitch.

If this situation occurs, please first pull the joystick to the end (positive angle of attack, the opposite for negative angle of attack). When the absolute value of the angle of attack reaches around 120, push the joystick to the end (positive angle of attack, the opposite for negative angle of attack). The aircraft will, due to inertia, exit the out-of-control zone near the 90-degree angle of attack.

We added AoA Limiter and G-force Limiter in the FBW.

AoA Limiter

Usually, the AoA Limiter triggers at a Angle of Attack of 12 degrees positive, or 10 degrees negative.
When AoA Limiter is activating, it will show "AoA Lim (-)[Pitch rate the AoA Lim inputed]" on HUD.
Like this:

You can disable AoA Limiter by activating ACRO. In this case, when AoA Limiter meets the condition, it will show the same as the above, but it is amber and a horizontal bar will appear in the middle of the text.
Like this:


Now it's for G-force Limiter.

G-force Limiter

The G-Force Limiter triggers at a G-force of 7.9 or -5.0 .
When G-force Limiter is activating, it will show "G Lim [The ratio of the pilot's flight inputs that are reduced]" on HUD.
Like this:

You can't disable G-force Limiter.


SOME FUNCTIONS

To jettison all of your weapon, you need to turn on the "JETTISON ARM" switch, then click "JETTISON" button.
This aircraft is equipped with an engine fire management system.
When the engine works normally, you can't discharge the agent.
If the system detects that the engine is on fire(need to be set in failures), it will arm the agent-discharge button, in this case, you can discharge the agent.
When the agent is discharged, you can't relight the engine.

CONTROLS

Activate Groups:

AG1: Open the canopy.
AG2: Extend refuel probe.
AG4: Open extra lights.


Others

Acro: Use the button in the cockpit, or use the Flight Computer.
Refuel probe: Use the Flight Computer.
Auto throttle: Use the button in the cockpit, por use the Flight Computer.
Autopilot: Use the button in the cockpit, por use the Flight Computer.
ILS (Instrument Landing System) & Airport selection: Use the Flight Computer.
Engine start & shutdown: Use the button in the cockpit.
You need to try them by yourselves. Maybe there're more functions, but I won't list them.

Have a try:)

OK, that's all. Have a great time!

Update log:

v1.4: Added an automatic landing system(In the second page of ACS page). Modified the mechanism by which fault simulation triggers the corresponding automatic system failure, ensuring that only a portion of the automatic modes are disabled by the corresponding fault. Added altitude data to the radar screen.
v1.3: The original fault simulation system has been optimized to make it easier to use.
v1.2: Changed the mechanism of the Semi-FreeCam, to make sure it won't over the maximum distance.
Changed the FBW to make sure it will center the output when it's parking.
v1.1: /Important/ The mechanism of the flight computer has been modified to enhance its detection of incorrect input formats and prevent erroneous formats from being entered into the target modification values
