ANN's Daily Aero-Term (04.12.21): Instrument Approach Operations [ICAO]

Aero-Terms!

Aero-Terms are designed to be a daily reminder of the terms, names, acronyms and explanations of the unique language that populates the aviation world. Aerospace, sport aviation, fixed wing, helo, you name it... it's all fair game.

Aero-Terms should serve as a quick but intriguing reminder of the terms you may use every day, or an introduction to an aspects of the Aero-World you may not yet be familiar with. ANN also encourages readers to go beyond the FMI link, and further research any intriguing terms.

Suggestions for future Aero-Terms are ALWAYS welcome, as are additions or discussion of the explanations given for each Aero-Term.

Instrument Approach Operations [ICAO]

An approach and landing using instruments for navigation guidance based on an instrument approach procedure. There are two methods for executing instrument approach operations:

  1. A two-dimensional (2D) instrument approach operation, using lateral navigation guidance only; and
  2. A three-dimensional (3D) instrument approach operation, using both lateral and vertical navigation guidance.
