PHX Software for Aeronautical Charting and IFR Procedure Design

PHX IFR Procedure Design Package
- Design all types of IFR procedures
- Document the complete procedure design process in real time by using the built-in Quality Assurance Assistant that can record the following:
- all entered parameters
- results of obstacle analysis
- screen shots
- custom commentary
- Calculate and draw the minimum stabilisation distance between two RNAV waypoints
- Calculate and draw the cross-track tolerance (XTT), along-track tolerance (ATT) and half the area width (1/2 A/W) for an RNAV waypoint using the VOR-DME or DME-DME criteria
- Draw the theoretical DME coverage for DME-DME based RNAV procedure
- Draw and analyse precision approaches:
- ILS basic surfaces
- ILS OAS surfaces including automatic OAS constants calculation and allow for steep angle approaches
- Collision risk model (CRM) analysis
- Draw and analyse various holding patterns:
- Race-track holding pattern
- Base turn holding pattern
- Procedure turn holding pattern
- VOR/DME race-track holding pattern
- Holding pattern overhead a VOR or NDB
- Draw and analyse departures:
- Standard departure
- RNAV departure
- Departure nominal track
- Draw and analyse en-route straight and turn segments
- Draw and analyse obstacle limitation surfaces defined by ICAO Annex 14 or UK CAP 168 criteria featuring:
- Runway organisation
- Custom parameters
- Draw and analyse the theoretical safeguarding area and surfaces of navigational aids
- Draw and analyse GPS/GNSS procedures:
- Basic GPS obstacle analyser
- Terminal arrival altitudes (TAA) construction and analysis
- Use various independent tools to design complex procedures:
- Nominal turn construction
- Turn protection area construction
- VOR and NDB radial construction
- Over-head tolerance of a VOR or NDB construction
- Visual circling construction
- Fix area construction using a combination of different types of navigational aids (VOR, NDB, DME)
- Non-precision final approach alignment calculation
- DME tolerance and slant range calculation and construction
- Indicated air speed (IAS) to true air speed (TAS) conversion
- Secondary MOC calculation
- Nominal approach altitudes calculation and construction taking into account the curvature of the earth
- Minimum sector altitude (MSA) construction and analysis
