## Example Workflow

1. Get access token
2. Create PPR entry (status: NEW) → Shows on arrivals board
3. Update status to LANDED → Shows on departures board
4. Update status to DEPARTED → Removes from departures board

## Testing Commands

```bash
# Store token
TOKEN=$(curl -s -X POST "http://localhost:8001/api/v1/auth/login" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "username=admin&password=admin123" | jq -r '.access_token')

# Create PPR
curl -X POST "http://localhost:8001/api/v1/pprs/" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"ac_reg":"G-TEST","ac_type":"C172","captain":"Test Pilot","in_from":"EGKB","eta":"2025-10-21T14:30:00","pob_in":2}'

# Check arrivals
curl -s "http://localhost:8001/api/v1/public/arrivals" | jq .

# Update status to LANDED
curl -X PATCH "http://localhost:8001/api/v1/pprs/1/status" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"status":"LANDED"}'
