A manual parachute release was refused
What ArduPilot says:
- Parachute: Too low
- Parachute: Landed
- ERR PARACHUTES (Subsys 15)
A release asked for by a switch or by the ground station was not carried out. “Parachute: Landed”: the copter is on the ground. “Parachute: Too low”: it is below CHUTE_ALT_MIN metres above home, where the canopy would not open in time. In the log these are “ERR PARACHUTES-3” and “ERR PARACHUTES-2”.
What to do, most likely first
The release switch was moved on the ground or during the landing.
FixNothing was released and nothing is wrong. Put the parachute on a switch you cannot knock by accident.
CHUTE_ALT_MINis higher than the height you fly at, so a release you need would be refused.CheckCompare
CHUTE_ALT_MINwith the height in the log when the release was asked for.FixSet
CHUTE_ALT_MINto the lowest height at which your parachute opens fully, as its maker states, and fly above it.
Parameters to look at
| Parameter | What it is |
|---|---|
CHUTE_ALT_MIN | Parachute min altitude in meters above home |
CHUTE_ENABLED | Parachute release enabled or disabled |
