Target Data

Target Altitude [Meters]

Altitude+(TargetDistance*sin(TargetElevation))

.
Target Longitude [Meters]

Longitude+((TargetDistance*cos(TargetElevation))*sin(TargetHeading))

.
Target Latitude [Meters]

Latitude+((TargetDistance*cos(TargetElevation))*cos(TargetHeading))

.
Target Speed [Meter/s] (Written by ChatGPT 3.5)

sqrt(pow(rate(TargetDistance*cos(TargetElevation)*sin(TargetHeading)+Longitude),2)+pow(rate(TargetDistance*cos(TargetElevation)*cos(TargetHeading)+Latitude),2))

Generates a velocity output in meters per second of a target by calculating it's longitude, latitude and altitude and using the rate of those to calculate for a hypotenuse between all 3.

.
Target Velocity Heading [Degrees]

atan2(rate(TargetDistance*cos(TargetElevation)*sin(TargetHeading)+Longitude),rate(TargetDistance*cos(TargetElevation)*cos(TargetHeading)+Latitude))

Provides an approximation for the heading of a target by calculating the heading of it's vector.
Thanks to @DarDragon for this code!

More Flight Data

3D Tachometer [Meters]

sum(GS)

Provides a scalar quantity for the distance your craft has travelled in 3D space.

.
Horizontal Component of Forward/Aft Velocity Vector [Meter/s]

(rate(Latitude)*cos(Heading)+rate(Longitude)*sin(Heading))

Gives the horizontal component of your craft's velocity but strictly in the forward/aft direction as a vector constraint.
Thanks to @KSB24 for this code!

.
Velocity-Based Heading [Degrees]

atan2(rate(Longitude),rate(Latitude))

Gives a heading output based off of your plane's trajectory rather than the direction its actually facing. Operates like AngleOfSlip if it were a global function.
Thanks to @KSB24 for this code!

.
Non-Quaternion Heading Output [Degrees]

Heading+(Heading<0?360:0)

Translates the typical output of the Heading variable from a quaternion output [-180,180] to a more understandable [0,360] degree range.

.
Forward/Reverse Differentiation [Boolean]

abs(AngleOfAttack)<90

This nifty bit of code gives a Boolean output depending on whether your craft is moving forward or not by determining if the angle of attack is less than 90°.
True = Forwards (1)
False = Backwards (-1)

.
Angle Of Descent [Degrees]

atan2(rate(Altitude),sqrt(pow(rate(Longitude),2)+pow(rate(Latitude),2)))

Provides an angle relative to the horizon based on the angle theta of your plane's current horizontal and vertical velocity.

.
Turn Radius [Meters]

abs(pow(GS,2)/((GForce-1)*9.81))

Provides a radius to an imaginary circle formed when your plane is changing, heading, pitch angle, or anything between.

.
Mach number [Mach]

TAS/(340-clamp((Altitude*0.003937),0,43))

Generates an accurate mach reading that adjusts based on altitude.

Ammo

Absolute ammo depletion [Boolean]

clamp01(sum((BOOLEAN?clamp01(ammo("WEAPON NAME")=0):0)))

This code gives a permanent output of 1 when a certain ammo type is depleted. Ignores inaccurate depletion reading caused by deactivation of a given weapon's Boolean operator(s).
Ex weapon is activated by action group 1, the code would look like

clamp01(sum((Activate1?clamp01(ammo("WEAPON NAME")=0):0)))

Thanks to @DarDragon for helping tremendously with writing this code!

Comment below ideas for generally useful functions and I'll add them to this forum post.
(Disclaimer I'm not gonna code super specific stuff like engine PID controllers, gear shifting, etc. but stuff that can be reused on many different planes such as target info and flight info I will definitely do)
