Definition
An instructional sequencing approach in which the instructor introduces basic, foundational material first and progressively adds layers of complexity as the learner demonstrates understanding. Each new step builds on what the student has already mastered, so concepts and skills are stacked in a manageable order rather than presented all at once.
Plain English
Start with the easy, basic stuff, then slowly add harder material once the student is ready for it. Build up step by step instead of dumping everything on them at the start.
Context Anchor
Used in flight instruction when an instructor demonstrates or teaches a maneuver, procedure, or cockpit task in stages.
Derivation
Simple comes from a Latin idea meaning “onefold” or not made of many parts. Complex comes from a Latin idea meaning “woven together.” That fits the teaching idea: begin with the one-part version, then add the parts that make the task more involved.
Why Pilots Care
Prevents the student from becoming overwhelmed by keeping each learning step manageable.
Intuition Check
Simple-to-complex does not mean making the lesson childish or less serious. It means teaching the real skill in a careful order, with each added step resting on something the student already understands.
Example Sentence 1
Following a simple-to-complex strategy, the instructor introduced straight-and-level flight before moving on to turns, climbs, and descents.
Example Sentence 2
Using the simple-to-complex strategy, the lesson began with basic power changes on the ground and progressed to full traffic pattern operations.
