TM-078 | King Air Pro Line 21 Navigation Architecture & Maintenance Evidence

Map navigation functions

Connect NAV and DME receivers, GPS, IAPS/FMC computation, CDU control, cockpit presentation and database-loading functions.

Separate availability from selected use

Interpret the named GPS data page and FMS control record together. Compare DME distance with the correct station and reference.

Interpret the named load record

Keep the target computer, compatible file, transfer stage and media condition together. Distinguish database loading from log writing.
Understand how the identified King Air B300/B300C Pro Line 21 NAV, DME, GPS, FMC/CDU and database-loading systems work together. The course combines an illustrated 48-page handbook, a source-qualified evidence explorer, coached investigations, fixed job records and a fresh independent review. Learn to distinguish a received signal from its displayed or audible output, available GPS data from selected FMC use, DME range from a different reference, and a completed file transfer from another computer’s status or a log-writing operation.

What's included?

  • 8 focused lessons
  • Completion certificate
  • 32-question final
  • 8 two-stage diagnostic cases
  • 48-page illustrated handbook

Understand how the systems connect

Trace GPS receiver data through the IAPS concentrators to FMC computation. Distinguish CDU panels from installed FMCs and optional provisions. Use the identified NAV, DME, GPS and DBU source tasks to explain the relationships.

Practice interpreting real maintenance evidence

Complete eight lessons, six prediction-and-Apply exercises, eight two-stage cases and six fixed records with 18 evidence classifications. The 12-decision independent review requires at least 80% and all eight critical decisions correct in one attempt. Pass the separate 32-question final with at least 26 correct answers. Complete the handbook, mastered lab and final to claim the certificate. Detailed supplier RF tests and practical qualification remain separate.
