The first GPS I used in the air was a Garmin 95 portable. Brick-shaped and nearly brick-sized, its etch-a-sketch screen was a still a revelation. We could go direct to airway fixes and watch the little black pixels approach just as the CDI needles swung to center. This was back when we taught instrument students how to eyeball a course direct to a fix defined by two VOR radials.

Key Takeaways:

The article outlines a challenging IFR simulator flight from KSHN to KPWT under adverse weather, designed to test pilot skills in complex navigation and decision-making.
It contrasts the distinct challenges and strategies for both traditional VOR and modern GPS users when executing departure procedures, intricate approach transitions, and missed approaches.
The scenario emphasizes the critical importance of situational awareness, proactive planning, and adaptability, particularly when managing strong crosswinds and rapid fix crossings.
A modern "fix crossing discipline" (CAPERS) is introduced, highlighting the need to combine traditional IFR skills with contemporary RNAV flight management.

The first GPS I used in the air was a Garmin 95 portable. Brick-shaped and nearly brick-sized, it’s etch-a-sketch screen was a still a revelation. We could go direct to airway fixes and watch the little black pixels approach just as the CDI needles swung to center. This was back when we taught instrument students how to eyeball a course “direct” to a fix defined by two VOR radials.

That technique has been rendered both unnecessary and verboten by RNAV and regulation respectively, but skills in intercepting fixes and radials are still required for IFR aplomb. Hitting fixes is what this challenge is all about. It’s a twist-fest if you don’t have a GPS. It should keep you moving even if you do. Either way, serious situational awareness is the key, so let’s chair-fly it before powering up the simulator.
