AeroCalc — Streamline Your Aerodynamics Analysis

AeroCalc Mobile — On-the-Go Aviation CalculationsAeroCalc Mobile brings powerful aviation calculation tools to your phone or tablet, enabling pilots, flight instructors, and aviation enthusiasts to perform accurate, reliable computations anytime and anywhere. Whether you’re preparing for a cross-country flight, quickly checking weight-and-balance before engine start, or comparing climb performance at different temperatures and densities, AeroCalc Mobile packages essential aeronautical calculators into a streamlined, easy-to-use app.

Key features

• Weight & Balance calculator — Quickly compute moment, center of gravity (CG) and CG limits for single- and multi-occupant configurations. Save aircraft profiles (empty weight, arm locations, max ramp/takeoff/landing weights) for fast preflight checks.
• Performance charts & takeoff/landing computations — Use built-in performance models and customizable aircraft profiles to estimate takeoff distance, accelerate-stop distance, landing distance, and required runway length under current conditions.
• Density altitude & pressure altitude tools — Convert between altitudes, calculate density altitude from temperature and pressure, and see performance impacts at different altitudes.
• Fuel planning & endurance/range estimators — Compute fuel required, endurance, and range using planned cruise power settings or fuel consumption rates. Include reserves and alternate planning.
• Weight conversions & unit support — Switch between imperial and metric units (lbs/kg, ft/m, °F/°C, nautical miles/kilometers) with persistent user preferences.
• Environmental inputs — Enter winds aloft, runway slope, temperature deviations, runway surface conditions, and runway elevation to refine performance outputs.
• Custom aircraft library — Add and manage multiple aircraft types with their specific configurations and limitations. Import/export profiles for sharing within flight departments.
• Preflight checklist integration — Link computed values to checklist items so that essential calculations are recorded and visible during the preflight routine.
• Offline capability — Core calculators work without internet access; optional cloud sync keeps profiles and logs updated across devices.
• Safety warnings & limits checks — Built-in alerts for overweight conditions, CG out-of-limits, or other unsafe configurations based on stored aircraft envelope data.

User interface and workflow

AeroCalc Mobile focuses on clarity and speed. The main workflow is organized around three tabs — Profiles, Calculators, and Logs — minimizing steps between data entry and actionable results.

• Profiles: Create aircraft entries with empty weight data, arm measurements, weight limits, and common load stations. Profiles can include manufacturer-provided performance modifiers and optional field notes (e.g., propeller pitch, aircraft modifications).
• Calculators: A grouped list of common tools — Weight & Balance, Takeoff/Landing, Density Altitude, Fuel Planning, and Conversions. Each calculator preloads values from the selected profile to reduce repetitive typing.
• Logs: Save each calculation session with time, location (optional), inputs, and outputs. Export logs as PDF or CSV for flight records or briefings.

The interface uses clear color-coding for status: green for within limits, amber for approach-to-limit, and red for out-of-limit conditions. Quick help icons explain the meaning of each parameter and offer brief examples where common input mistakes occur.

Accuracy, data sources, and customization

AeroCalc Mobile emphasizes both accuracy and transparency. Performance models are based on manufacturer charts and standard aerospace formulas; where possible, the app references the relevant chart or formula used for a calculation. Users can:

• Input manufacturer chart tables for their aircraft, allowing the app to interpolate takeoff/landing distances and performance numbers specific to their model.
• Adjust performance multipliers (e.g., for propeller efficiency, aircraft weight growth, or worn brakes) to reflect real-world operational differences.
• Use advanced interpolation methods (bilinear, spline) for higher-fidelity chart lookups when interpolating between weight, pressure altitude, and temperature cells.

All assumptions and modifiers are shown alongside results so pilots can quickly see which factors influenced a performance estimate.

Safety and regulatory considerations

AeroCalc Mobile is designed as a decision-support tool, not a replacement for official aircraft flight manuals (AFM/POH) or certified performance calculation procedures. The app includes multiple in-app reminders:

• Always cross-check with the aircraft’s POH/AFM.
• Use the app’s manufacturer chart import to mirror official tables when available.
• Maintain conservative safety margins — consider using higher safety factors for critical phases like short-field takeoff or landing over obstacles.

The app can be configured to require a user acknowledgment that they understand the tool’s advisory nature before viewing critical outputs (for use in flight training or airline SOP environments).

Typical use cases

• Private pilot doing a summer mountain departure: compute density altitude, updated takeoff distance with uphill runway slope and headwind, and check CG with full baggage.
• Flight school instructor: store multiple student aircraft profiles, quickly verify student preflight calculations, and export logs for lesson debriefs.
• Charter pilot planning a short-turn at an unfamiliar airport: on-the-spot landing distance check under wet runway conditions and crosswind component calculation.
• Maintenance or operations manager: bulk-import aircraft profiles and distribute standard performance modifiers to fleet pilots.

Technical implementation highlights

• Local database (SQLite) for profiles, logs, and cached chart data.
• Modular calculator engine so new tools and aircraft-specific chart parsers can be added via updates without changing core UI.
• Secure cloud sync (optional) with end-to-end encryption for profile backups and team sharing.
• Accessibility features: large-font mode for sunlight readability, high-contrast themes, and screen-reader support for visually impaired pilots.
• Battery-efficient background processing for long cross-country flights when the device is connected to avionics power.

Pricing model and editions

• Free tier: basic calculators (weight & balance, density altitude, unit conversions), single aircraft profile, offline access.
• Pro subscription: unlimited profiles, chart import, advanced performance calculators, cloud sync, PDF exports, and priority support.
• Team/Enterprise: fleet management features, centralized profile distribution, audit logs, and custom integrations with dispatch systems.

Example workflow: preflight using AeroCalc Mobile

1. Select aircraft profile (preloaded with empty weight and arm values).
2. Enter occupant and baggage weights, fuel load, and planned fuel burn.
3. Run Weight & Balance; verify CG is within limits (green) or adjust seating/fuel accordingly.
4. Enter departure airport, runway, temperature, altimeter, winds, and runway surface condition.
5. Run Takeoff Performance: review takeoff distance with margin and any warnings (e.g., insufficient runway length).
6. Save the session to Logs and export a PDF snapshot for the logbook or flight folder.

Conclusion

AeroCalc Mobile aims to be the pocket-sized copilot for pilots who need fast, transparent, and accurate aviation calculations. By combining manufacturer-accurate performance models, flexible aircraft profiles, and a clean, safety-first interface, the app helps aviators make informed, confidence-inspiring decisions on the ground and in the air.
