Eliminate manual error from your workflow. A comprehensive suite of PANS-OPS and TERPS calculation tools designed for the modern procedure designer. Our aviation calculator software validates your math instantly.
Complex PANS-OPS Mathematics. Simplified.
Forget manual spreadsheets and the risk of human error. Access a comprehensive library of validated PANS-OPS and TERPS algorithms through a streamlined, non-intrusive interface that keeps your CAD workspace clear.
Airspeed & Distance Calculator
Perform critical flight dynamic conversions instantly. Ensure your turn radii and timing calculations are based on precise True Airspeed (TAS) values.
- IAS to TAS Conversion: Calculates True Airspeed based on altitude, temperature (ISA deviation), and compressibility.
- Speed Conversion: Knots to km/h, m/s, and ft/min.
- Distance Logic: Slant range vs ground distance corrections for DME arcs.
Wind Spiral & Turn Calculator
Automate the most complex aspect of turn area construction. Generate precise coordinates for protection areas expanded by wind effect.
- Wind Spiral Calculation: Derives the expansion of the turn area based on omnidirectional wind (ICAO Doc 8168).
- Turn Templates: Standard bank angle and rate-of-turn parameters.
- Drift Calculation: Assessment of wind drift for holding patterns and racetracks.
RNAV & BaroVNAV Calculator
Access the mathematical constants required for Performance Based Navigation (PBN) design without searching through the manuals.
- Segment Tolerances: Instant retrieval of XTT (Cross Track) and ATT (Along Track) values for RNP APCH.
- BaroVNAV: Temperature correction calculations for vertical path angles (VPA).
- Fix Tolerances: GNSS waypoint and fly-by/fly-over turn anticipation distances.
ILS OCH & OAS Calculator
Simplify the complex geometry of Precision Approaches. The calculator handles the heavy lifting for Obstacle Assessment Surfaces.
- OAS Coefficients: Automatically calculates the A, B, and C constants for OAS surface generation.
- OCH Calculation: Determines Obstacle Clearance Height based on the Collision Risk Model (CRM) or OAS penetration.
- Glidepath Height: Checks threshold crossing heights (TCH) and RDH values.
Visibility & Tolerances
Finalise your procedure with operational checks and system error budgets.
- Approach Visibility MOS: Calculates required visibility minima based on lighting facilities (ALS) and OCH.
- DME Tolerance: Computes the total system error budget for DME/DME fixes.
- MOC Calculation: Minimum Obstacle Clearance values for various phases of flight (Initial, Intermediate, Final).
Workflow Integration
Designed to sit alongside your CAD station as a rapid-check utility.
- Clipboard Support: Copy results directly into AutoCAD or MicroStation text fields.
- Report Generation: Export calculation logs for Quality Assurance (QA) documentation.
- Independent Verification: Use the calculator to cross-check automated CAD outputs.
