Elastomeric lines are connected to a model aircraft and swivel or are otherwise swivelably secured to a portion of the navaid pegs, the opposite end of which is secured to the model aircraft above a pair of compass roses, each of which rotatable relative to the point of attachment of the line as well as the model aircraft or selectively may be fixed with regard to the model aircraft. The terrain plate is provided desirably with symbols of navigational aids corresponding to those of published approach plates, high density areas, and in route navigational charts of the character regularly used by airline pilots, and other pilots flying under instrument flight rules, irrespective of whether they have ground contact or must rely totally on the instruments for navigation.
