ICAO DRILL Codes: Immediate access to Dangerous Goods emergency response procedures—vital for safety briefings. Hypoxia & TUC Reference: Essential physiological tables for Time of Useful Consciousness and hypoxia symptoms. NAVIGATION & WIND SOLUTIONS Heading / Track / WCA: Solve the wind triangle instantly. Get True Heading (TH) and Ground Speed (GS) to maintain your desired course. In-Flight Wind: Determine actual wind speed and direction aloft by inputting your current flight parameters. Distance & Track Calculator: Calculate Great Circle distance and initial/return headings between any two global coordinates. Crosswind Calculator: Visualize Headwind and Crosswind components with customizable limits for safe takeoff and landing. PERFORMANCE & SPEED TAS / Mach / Sound Speed: Master high-altitude performance. Calculate True Airspeed, Mach Number, and Local Speed of Sound (LSS) with precision. Density & Pressure Altitude: The key to performance planning. Accurately determine PA and DA based on field elevation and temperature. GS to IAS/TAS Conversion: Convert Ground Speed back to Indicated or True Airspeed for accurate timing and logbook entries. FUEL & EFFICIENCY (NEW) JET A-1 Volume to Weight: Essential for dispatchers and pilots. Convert fuel volume to weight (Liters to KG/LBS) accounting for real-time fuel density and temperature. Unit Converter Pro: The ultimate "Swiss Army Knife" for aviation. Convert Mass, Distance, Pressure, Speed, and Temperature between Metric and Imperial standards effortlessly. GRADIENTS & PROFILES (NEW) Runway & Approach Gradients: Calculate required climb gradients (ft/nm, %) for instrument departures and missed approach procedures to ensure obstacle clearance. Convert between percentages, degrees, and ft/nm to ensure compliance with ICAO/FAA chart requirements and safe obstacle clearance. DME / Altitude Check: Verify your vertical profile. Determine the exact height or descent rate required at specific DME distances. TIME & SCHEDULING Sunrise / Sunset (UTC): Get precise Civil Dawn, Dusk, and Solar timings for any location to determine legal night flight periods. Flight Time & Crew Rest: Manage your logbook and duty periods. Calculate total flight times and generate FDP-compliant crew rest schedules instantly. KEY BENEFITS Unrivaled Accuracy: Built on ICAO/FAA standard atmosphere formulas. All-in-One Workflow: No internet connection required for calculations. Access 20+ powerful tools from a single menu. Download Flight Computer today and experience the new standard in digital flight planning.

Crabwise is an offline E6B flight computer built for student and private pilots: the six calculations you learn on paper, with type large enough to read at a glance. WIND & GROUND SPEED Solve the wind triangle both directions: find your heading and ground speed, or work backward from heading, track, and ground speed to find the wind. PRESSURE & DENSITY ALTITUDE See the classroom rule of thumb and the exact ICAO Doc 7488 answer side by side, so you know how much margin you actually have. TRUE AIRSPEED & MACH The quick 2%-per-1000-ft approximation and the exact compressible calculation, together. FUEL / TIME / DISTANCE Solve for any one of the three from the other two. CROSSWIND Headwind and crosswind components for any runway and wind. CONVERSIONS Seven unit families: distance, speed, altitude, temperature, pressure, weight, volume. CRABWISE PRO, ONE-TIME PURCHASE ($9.99) - Aircraft profiles: save cruise speed, fuel burn, usable fuel, empty weight and arm, and limits for every aircraft you fly. - Leg planner: chain legs from true course to compass heading, with running totals for time and fuel. - Weight & balance: plot your loading against your aircraft's envelope, checked live as you type. - History & export: save any result and export it as text or CSV.
