SIM_Parachute deploys as soon as the PWM on SIM_PARA_PIN reads 1250 or more, and it starts watching that pin the moment the pin number is set. The parachute tests set the pin in the same set_parameters() call as the release servo's function, which races the servo output: assigning SERVO9_FUNCTION=27 leaves the channel at its previous value until AP_Parachute drives it to CHUTE_SERVO_OFF (1100 by default, below the trigger), and anything at or above 1250 in that window fires the chute during setup. The test then fails in a way which does not look like a setup problem at all: "BANG! Parachute deployed" arrives before the test starts waiting for it, and the real release later in the mission is silent because the chute has already gone, so the wait times out with "Failed to receive text: bang". Seen overnight in Parachute and in GCSFailsafe's parachute subtest, one run in 26 each. Configure the vehicle first, wait for the release channel to reach its off position, and only then let the simulation watch the pin. Done in one helper, as four tests set this up the same way.

ArduPilot Project
ArduPilot is the most advanced, full-featured, and reliable open source autopilot software available. It has been under development since 2010 by a diverse team of professional engineers, computer scientists, and community contributors. Our autopilot software is capable of controlling almost any vehicle system imaginable, from conventional airplanes, quad planes, multi-rotors, and helicopters to rovers, boats, balance bots, and even submarines. It is continually being expanded to provide support for new emerging vehicle types.
The ArduPilot project is made up of
