new DEMO Mode: AFF Alti Simulation

23
Mar

AFF-DEMO is an Free Fall training simulator that demonstrates the altitude progression during an AFF (Accelerated Free Fall) student jump. The mode simulates a realistic descent profile with two phases and provides audio/visual feedback throughout the descent.

 

Descent Profile

Phase 1: Fast Descent (50 m/s)
Starts at 4,115 meters / 13500 ft
Descends at 50 m/s (freefall)
Audio alerts at:
1,700m / 5600 ft: single beep
1,550m / 5100 ft: double beep
transition to slow descent at 1,500m / 4900 ft: long beep
 
Phase 2: Slow Descent (5 m/s)
Begins at 1,500 meters 4900 ft
Descends at 5 m/s (simulating canopy deployment/descent)
Continues until reaching ground level (0m)

 

Button Controls

Button Action Behavior
SetDZ (Right Button) Short Press (150ms – 2s) Start + Pause/Resume descent timer
Set0 (Middle Button) Long Press (2+ seconds) Reset to IDLE state
Mode Button (Left Button) Press Cycle through device modes
 

Visual Feedback

LED Pixel Colors

State Color Meaning
IDLE Red Waiting to start descent
Fast Descent Green Descending at 50 m/s
Slow Descent Blue Descending at 5 m/s
Paused Red Descent paused

Note: Models without WS2812 LED (e.g., airlogoneMiniV31) will not display colors but all other features work normally.

Audio Feedback

Event Sound
Start descent Single beep
Altitude 1,700m Single beep
Altitude 1,550m Double beep
Transition to slow descent Triple beep
Pause/Resume Click
Reset to IDLE Double beep

Usage Example

  1. Enter AFF-DEMO Mode: Press Mode button to cycle to “AFF-DEMO”
  2. Start Descent: Short press SetDZ button (right) → descent begins (green pixel, single beep)
  3. Pause Descent: Short press SetDZ button again → descent pauses (red pixel, click sound)
  4. Resume Descent: Press SetDZ button again → descent resumes (green/blue pixel, click sound)
  5. Reset to Start: Press Set0 button (left) for 2+ seconds → returns to IDLE (red pixel, double beep)
  6. Auto-completion: Descent automatically completes when reaching 0m, returns to IDLE after 10 seconds
