Problem with CH47 Flight altitude during delivery

We would like to have the Bradley helicopter delivered via the CH-47.

Unfortunately, this is still very often prone to errors.

The CH-47's altitude is not always determined correctly. Often, the CH-47 gets stuck on trees during approach, loses the Bradley and sometimes even damages itself.

Use these settings to help maintain minimum altitude:

 

  "CH47 Chinook Delivery Options": {
    "Map Scale Distance Away to Spawn CH47 (eg: 1.0 = 1 x Map Size Distance)": 0.01,
    "Height of CH47 When it Spawns (Increase if it Spawns in Terrain)": 50.0,
    "Minimum Height of CH47 as it Approaches Landing Zone (Increase if it Hits Terrain)": 40.0
  },
