XGS
XGS (Landing Speed Plugin Reloaded) is a standalone plugin by hotbso that displays detailed landing quality data — from sink rate and G-forces to touchdown distance and centerline deviation.
Background
- Developer: hotbso (Holger Teutsch)
- Repository: github.com/hotbso/xgs (open source, GPL-2.0)
- Platforms: Windows, macOS, Linux (native binaries)
- Compatibility: X-Plane 12
XGS is an evolution of the original Landing Speed Plugin and is actively maintained.
Features
- Sink rate & G-forces: Maximum sink rate (fpm) and maximum G-force on landing
- Quality rating: Textual landing quality assessment from a configurable file (e.g., "Smooth landing", "Hard landing, requires inspection")
- Speed & pitch: Ground speed and pitch angle at touchdown
- Bank angle: Lateral bank angle at touchdown
- Touchdown distance: Distance from threshold crossing to touchdown
- Centerline deviation: Lateral and angular deviation from runway centerline
- ToLiss detection: For ToLiss models, XGS detects ground contact via main landing gear strut compression and additionally reports nosewheel touchdown distance
Configurable Rating Scales
XGS ships with a default rating scale and an aircraft-specific scale for Airbus types (based on real-world inspection thresholds). Custom scales can be placed as text files in the aircraft directory.
Value in Flight Simulation
The built-in X-Plane instruments show no detailed landing quality data after touchdown. XGS fills this gap with immediate feedback — useful for training consistent landings. The ToLiss-specific gear detection provides more precise data than the generic method.
