Notes

This function sets up the initial conditions for a hover segment with fixed altitude and duration. The segment represents stationary flight with no translational velocity components.

Calculation Process

1. Check initial altitude

2. Scale time points over hover duration:

   t = t_norm * duration + t_initial

3. Set velocity components to zero:

   • v_x = 0

   • v_y = 0

   • v_z = 0

4. Set position at hover altitude

Major Assumptions

• Perfect hover (no drift)

• Fixed altitude

• No translational velocity

• No atmospheric variations

• Quasi-steady state
