Ground Cue
Overview
The Ground Cue provides specialized motion cueing optimized for ground operations in aircraft simulations. It works in conjunction with the Primary Cue, automatically transitioning between ground-based and airborne motion profiles based on the aircraft's altitude.
Key features:
Dedicated motion profile for ground operations (taxi, takeoff, landing)
Smooth transition between ground and air motion profiles
Configurable altitude-based blending
Aircraft-specific (not active for other vehicle types)
Requires valid altitude telemetry data from simulation

Controls
Altitude Settings
Ground Altitude: Set this to match the reported altitude when aircraft is on the ground
Check "Source Data" display while on runway to determine correct value
Some simulators report non-zero altitudes for ground level
Air Altitude: Defines height at which Primary Cue takes full control
Motion smoothly transitions between Ground/Primary profiles between these altitudes
Axis Controls
Each motion axis has identical controls to the Primary Cue:
Enable/Disable: Toggle individual axis activity
Link to Primary: Inherit settings from Primary Cue profile
Isolate: Temporarily disable all other axes for focused tuning
Smoothness: Filter strength
Washout: Return-to-center speed
Gain: Motion intensity multiplier
Tuning Tips
Initial Setup
Set Ground Altitude first:
Park aircraft on runway
Check Source Data altitude reading
Set Ground Altitude to match
Set Air Altitude:
Recommended 10-50m above Ground Altitude
Larger difference = more gradual transition
Smaller difference = quicker transition
Ground Profile Tuning
Start with Primary Cue settings
Modify for ground operations:
Reduce gains for smoother taxi
Increase smoothness to dampen runway bumps
Adjust washout for better brake/acceleration feel
Testing
Test full takeoff sequence:
Ground handling
Rotation
Initial climb
Verify smooth transition to Primary Cue
Test landing sequence:
Approach
Touchdown
Rollout
Common Adjustments
Rough Ground Handling: Increase smoothness, reduce gains
Weak Brake Feel: Increase surge axis gain
Harsh Touchdown: Adjust heave axis smoothness
Poor Directional Feel: Fine-tune yaw/sway settings
Remember: Changes take effect in real-time, allowing immediate feedback during tuning.
