Notes

This function sets up the initial conditions for a vertical climb segment with constant climb rate. The segment handles pure vertical motion with no horizontal velocity components.

Calculation Process

1. Check initial conditions

2. Discretize altitude profile:

   alt = alt0 + (altf - alt0)*t_norm

3. Calculate time required:

   dt = (altf - alt0)/climb_rate

4. Set velocity components:

   • v_x = 0

   • v_z = -climb_rate (z points down)

5. Scale time points: t = t_norm * dt

Major Assumptions

• Constant climb rate

• Pure vertical motion

• No horizontal velocity

• No atmospheric variations

• Quasi-steady climb
