Overview

The DELAY parameter group appears to be a legacy or miscategorized entry in the documentation structure.

In modern ArduPilot, delays are almost always associated with the specific system they affect, to correct for sensor lag or actuation timing.

Common Delays found elsewhere

• VISO_DELAY_MS: Visual Odometry latency.
• CHUTE_DELAY_MS: Parachute release delay.
• GPS_DELAY_MS: GPS measurement lag.
• FLOW_DELAY_MS: Optical Flow sensor lag.

Developer Notes

• Status: Likely deprecated or an extraction artifact.
