Safety Notice
Essential safety information for all users
🚨 EMERGENCY PROCEDURES
IN CASE OF IN-FLIGHT EMERGENCY
FLY THE AIRCRAFT
Maintain aircraft control at all times. Aviate first.
NAVIGATE
Ensure safe flight path and terrain clearance.
COMMUNICATE
Contact ATC when workload permits. Squawk 7700 if necessary.
USE OFFICIAL PROCEDURES
Reference aircraft manufacturer's emergency procedures, not custom checklists.
Aviation Safety Fundamentals
Official Documentation First
Always verify custom checklists against the official Pilot's Operating Handbook (POH) or Aircraft Flight Manual (AFM). Manufacturer documentation supersedes all custom checklists.
Verification Required
Before first use, verify every item in your custom checklist with a certified flight instructor or authorized maintenance personnel familiar with your specific aircraft.
Regular Updates
Review and update checklists whenever aircraft modifications occur, new service bulletins are issued, or regulatory requirements change.
Crew Coordination
Ensure all crew members are familiar with custom checklists. Brief any differences from standard procedures during pre-flight briefings.
Regulatory Compliance
Legal Requirements
Custom checklists do not replace regulatory requirements. You must comply with all applicable regulations from:
- Federal Aviation Administration (FAA)
- European Union Aviation Safety Agency (EASA)
- Transport Canada Civil Aviation (TCCA)
- Civil Aviation Safety Authority (CASA)
- Your local aviation authority
The pilot-in-command is ultimately responsible for the safe operation of the aircraft and regulatory compliance.
Checklist Best Practices
Double Verification
Critical items (fuel, weight & balance, weather minimums) should be verified by two independent sources.
Time-Critical Items
Memory items for emergencies should be practiced regularly and never rely solely on electronic checklists.
Backup Systems
Always carry paper backup checklists. Electronic devices can fail at critical moments.
Environmental Factors
Consider density altitude, runway conditions, and weather when using performance checklists.
Flow Patterns
Use checklists to verify flow patterns, not replace them. Maintain situational awareness.
Human Factors
Design checklists considering fatigue, stress, and workload. Keep critical items clear and concise.
Known Limitations
Not for Primary Navigation
This app is not certified for primary navigation or instrument flight procedures.
No Performance Calculations
The app does not calculate weight & balance, fuel burn, or performance data.
Device Limitations
Screen visibility in bright sunlight, battery life, and device reliability are user responsibilities.
No Real-Time Updates
The app does not provide real-time weather, NOTAMS, or TFR information.
Simulator Use Guidelines
🕹️ Flight Simulation
When using ACE Checklist Editor with flight simulators:
- Ideal for practicing checklist flows and procedures
- Helps build muscle memory for real operations
- Test custom checklists before real-world use
- Remember: simulator procedures may differ from real aircraft

Final Safety Reminder
Snow Tree is a tool designed to assist pilots in creating and managing checklists. It is not a substitute for proper training, sound judgment, or official documentation.
Always prioritize safety over convenience. When in doubt, consult official sources, seek guidance from qualified instructors, and follow established procedures.
