CHUTE_ parameters¶

8 parameters in the CHUTE_ family. ArduCopter 4.7 only — other vehicles share many of these names but not always the same ranges or meanings.

CHUTE_ALT_MIN¶

Parachute min altitude in meters above home

Parachute min altitude above home. Parachute will not be released below this altitude. 0 to disable alt check.

Units	`m`
Range	`0` to `32000`
Increment	`1`
User level	Standard

CHUTE_CRT_SINK¶

Critical sink speed rate in m/s to trigger emergency parachute

Release parachute when critical sink rate is reached

Units	`m/s`
Range	`0` to `15`
Increment	`1`
User level	Standard

CHUTE_DELAY_MS¶

Parachute release delay

Delay in millseconds between motor stop and chute release

Units	`ms`
Range	`0` to `5000`
Increment	`1`
User level	Standard

CHUTE_ENABLED¶

Parachute release enabled or disabled

Parachute release enabled or disabled

User level

Standard

Values¶

Value	Meaning
`0`	Disabled
`1`	Enabled

CHUTE_OPTIONS¶

User level

Standard

Bitmask¶

Value	Meaning
`0`	hold open forever after release
`1`	skip disarm before parachute release

CHUTE_SERVO_OFF¶

Servo OFF PWM value

Parachute Servo PWM value in microseconds when parachute is not released

Units	`PWM`

Increment	`1`
User level	Standard

CHUTE_TYPE¶

Parachute release mechanism type (relay or servo)

Parachute release mechanism type (relay number in versions prior to 4.5, or servo). Values 0-3 all are relay. Relay number used for release is set by RELAYx_FUNCTION in 4.5 or later.

Values¶

Value	Meaning
`0`	Relay
