Rotatable Layer Navigation Device for Holding Pattern Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
New aircraft pilots face challenges in learning to execute holding patterns during instrument training, particularly when receiving instructions from air traffic control while already flying.
Innovation Solution
A navigation training device comprising multiple layers that can be rotated to visualize holding patterns, including a base layer, a circular layer with degree markings, a second circular layer with markings for right and left turn holding patterns, and a semicircle layer for obscuring unused holding pattern markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple variables and instructions are provided for holding patterns, then the training comprehensiveness is improved, but the learning difficulty increases for new pilots
Solution Approach 1:
The training device segments the holding pattern information into multiple distinct layers: a base layer with degree markings, a holding pattern layer with right and left turn patterns, and a semicircle layer for obscuring. This segmentation allows pilots to study each component separately and understand the variables in manageable portions rather than overwhelming all-at-once complexity.
Solution Approach 2:
The patent transitions from two-dimensional static charts to a three-dimensional multi-layer rotatable device. By adding the vertical dimension through stacked layers that can be rotated independently, the device presents comprehensive holding pattern information in a spatially organized manner that reduces cognitive load and improves understanding.
2Adaptability or versatility
If holding pattern instructions are given while the pilot is already flying, then the realism of training is improved, but the execution accuracy decreases
Solution Approach 1:
The training device incorporates dynamic rotatable layers that can be manipulated during use. The holding pattern layer and semicircle layer can be rotated to different orientations, allowing pilots to practice adjusting to various ATC instructions and wind conditions. This dynamic interaction simulates the real-world scenario of receiving instructions mid-flight while maintaining precision through controlled manipulation.
Solution Approach 2:
The device provides visual feedback through the alignment of markings across layers. When layers are rotated to correct orientations, the degree markings and holding pattern markings align to show the proper configuration, giving pilots immediate feedback on their understanding and execution accuracy.
3Loss of information
If all holding pattern markings are displayed, then the information completeness is improved, but the visual clarity decreases due to distraction from unused patterns
Solution Approach 1:
The semicircle layer acts as a masking element that extracts or removes the visual distraction of unused holding pattern markings. By physically blocking portions of the holding pattern layer with the semicircle overlay, the device presents only the relevant information for the current training scenario, improving visual clarity while maintaining access to complete information when needed.
Solution Approach 2:
The semicircle layer is pre-positioned to obscure specific portions of the holding pattern markings before the pilot begins a training exercise. This preliminary action of masking irrelevant information prepares the visual field for focused study of the applicable holding pattern without the distraction of alternative patterns.

AI summary
In some examples, a navigation training device includes a base having an aperture through a center point of the base. The base includes a plurality of first markings equidistantly spaced along an outer edge of the base. The navigation training device also includes a first layer having an aperture through a center point of the first layer. The first layer includes a plurality of second markings including a directional marking and section markings visually dividing a top surface of the first layer into three sections. The navigation training device also includes a connecting pin passing through the apertures of the base and the first layer.
