Everything You Need in the Cockpit

From pre-flight to touchdown, Sims Checklist covers every phase of your virtual flight.

✈️

Checklists for 3 Aircraft

Complete pre-flight, before-taxi, before-takeoff, and in-flight checklists for Cessna 172 Skyhawk, Cirrus SR-22, and Citation X.

⛽

Fuel Calculator

Plan your fuel for the trip considering distance, wind, and alternate airport using predefined aircraft performance data.

🌤️

METAR/TAF Weather

Visualize wind direction, select preferred runway for headwind, and save your top airports for quick access.

🗺️

85,000+ Airports Database

Full offline database from OurAirports. Explore airports, runways, frequencies, and search by ICAO or name.

🎛️

QFE Helper

Convert QFE to QNH and meters AGL to feet ASL. Essential for modern aircraft that don't support QFE.

❄️

Cold Temp Corrector

FAA segment-based altitude correction for cold weather approaches. Auto-loads airport elevation and METAR temperature.

How It Works

Four Steps to a Safe Flight

From aircraft selection to final approach, every step covered.

1

Select Your Aircraft

Choose from Cessna 172, Cirrus SR-22, or Citation X with pre-loaded checklists.

2

Load Checklist & Calculate Fuel

Proceed through checklists and calculate fuel for your route with wind and alternate data.

3

Check METAR & Runway Wind

Review weather conditions and visualize headwind/crosswind components on your destination runway.

4

QFE & Temp Correction

Apply QFE-to-QNH conversion and cold temperature altitude correction during final approach.

FAQ

Common Questions

Everything you need to know before your first flight.

Does it work without internet?

Yes. All checklists and the airport database work offline. METAR/TAF weather data requires an internet connection to fetch from CheckWX API.

Which aircraft are supported?

Currently three aircraft: Cessna 172 Skyhawk (the classic trainer), Cirrus SR-22 (modern GA with glass cockpit), and Cessna Citation X (X-Plane 12 default, business jet). More aircraft may be added in future updates.

Will there be an iOS version?

Currently available on Android and Desktop (Windows, Linux, macOS). Follow the GitHub repository for updates on platform expansion.

Where does the airport data come from?

The airport database is sourced from OurAirports, a community-driven project with 85,000+ airports worldwide. Data is fetched from CSV files and stored in a local SQLite database for incredibly fast performance.

Why are runway headings in true courses, not magnetic?

METAR wind reports reference true north, not magnetic. To accurately visualize headwind and crosswind components relative to your aircraft's track, we use true course runway headings. This ensures correct wind component calculation for your flight planning.
