RTL dives to RTL_ALT, does not descend linearly as documentation says

ArduPlane VTOL Plane
1

Hello,

My VTOL T1 Ranger (arduplane firmware 4.5.7) dives at pitch limit to RTL_ALT if above RTL_ALT when QRTL activated. The documentation says it should linearly descend to RTL_ALT if above RTL_ ALT.

Is there a parameter to determine if plane should go straight to RTL_ALT or linearly descend to it based on distance from RTL?

Thanks in advance.
