What you will be able to do

  • ✓ Distinguish SVS, SVGS, EVS, EFVS and CVS, and state which can earn operational credit
  • ✓ Explain terrain and obstacle data quality under DO-200B, infrared and millimetre-wave sensors, and head-up versus head-down presentation
  • ✓ Apply 14 CFR 91.176 and 61.66, and explain the roles of AC 20-167B, AC 20-185 and AC 90-106B
  • ✓ Apply ICAO Doc 9365 concepts and the EU rules on EFVS 200 and SPA.LVO, and describe certification under CS-AWO and CS-25
  • ✓ Manage human factors, failures, maintenance and database updates, and assess suppliers and emerging trends
