ClearNav - USER Manual (v5.i2) CONTROLLER ClearNav operation is very intuitive and many pilots start using the system immediately with little or no tutorial. The initial sections of this manual therefore describe system function in abbreviated detail for those who would like to take this 'plug-n-play' approach. Most of the graphics in the manual also display drill-down images or explanations if you mouseover or click. Other following sections will review all system features in more detail to explain complex operations, calculations, and design logic. We will therefore start the manual with a review of hand-controller function as it is your communication interface to all ClearNav features. HAND CONTROLLER The nine-button hand controller buttons perform select, zoom and cursor movement functions like mice or game controllers. MENU and FOCUS support specific ClearNav features. Zoom in (*) Lcfi Arraw Down Arrow-Zoom Out (-) .— Menu ' Up Arrow ’m'~ Right Arrow "'Select ^ FflCUB MENU immediately displays/hides the ribbon menu - which gives the pilot access to all supporting screens and functions. FOCUS immediately returns to the Moving Map when in any other screen ... or highlights the moving map Cursor Box for 5 seconds to allow easy identification on the navigation screen. The Cursor Box can be moved quickly and precisely to any location on or beyond the displayed map - and the list of enclosed Waypoints and SUAs will be displayed in a new window when the pilot hits the SELECT button on the controller. The pilot can scroll down the list and select any turnpoint as an immediate destination - or just review navigation or airport information in the lower window. SUA information is also displayed in a separate tabbed window. The pilot can also mark lift or create a mark point for future reference. The table following summarizes the behavior of the hand controller buttons in the primary screen types that support ClearNav navigation functions.
