Because you’re on the lookout for an arcade kind of motion, I’ll make simplifications that may fit your use case.
I’ll assume that you just’re aware of the second legislation of Newton, in addition to integration to compute velocity and place primarily based on acceleration.

An airplane within the air have 6 levels of freedom: [X,Y,Z] are the coordinates in house (place) and the pitch, roll and yaw are the orientation across the airplane’s middle of gravity.
Plane axis
(Discover the axis orientation, specifically the Z axis pointing down, they’re normal in aeronautics)

Planes within the air are topic to 4 forces: raise, weight, thrust and friction (airdrag).
The resultant of those forces determines the second and general drive that may speed up and switch the airplane.
Planes forces
(supply: cap-ny153.org)

Weight
The well-known components $W = m.g$

Thrust
In your simplify mannequin, it could possibly be a relentless multiplied by a person enter.

Drag
In actuality: $frac{1}{2}.rho.S.V^2.C_x$
With

  • $rho$ the air density
  • $S$ the equal floor of your airplane (extra wing floor -> extra drag and raise)
  • $V$ the airplane airspeed (velocity relative to the air: a airplane at 100 kts with a entrance wind of 20 kts has an airspeed of 120 kts)
  • $C_x$ the drag coefficient relying on the airplane geometry and the angle of incidence

In your simplified mannequin: $A.V^2$ with A a well-tuned fixed and V the airspeed of your airplane.

Carry
In actuality: $frac{1}{2}.rho.S.V^2.C_y$
In your simplified mannequin : $A.V^2$ with A a well-tuned fixed and V the airspeed of your airplane.
Word that drag and raise are very comparable. The coefficients $C_x$ and $C_y$ are associated and depend upon the airplane geometry in addition to the angle of incidence, however your easy mannequin doesn’t want that.

It is sufficient to compute simply the trajectory of the airplane, however what about orientation? You have to know the purpose of utility of those forces relative to the middle of gravity of your airplane.
Nevertheless, in arcade physics, the angular acceleration could possibly be so simple as a relentless multiplied by a person enter. Built-in twice over time, that might give the angular place. Your job might be to tune the constants to realize a desired habits.
