Abstract
Abstract A training aid for simulating the actions of a magnetic compass under various flight conditions, including a pedestal extending upwardly from a base for supporting a compass wheel rotatably mounted thereon. A weight is suspended on a flexible cord from said compass wheel and a guide member extends from the pedestal. The flexible cord passes through an eyelet formed in the end of the guide member, thereby limiting the rotational movement of the compass wheel about the pedestal. A compass window is simulated through the utilization of a rigid sheet of material having an opening therein; the simulated compass window is positionable about the compass wheel by mounting the window frame for pivotal movement about the pedestal. The simulated compass window is provided with a lubber line.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A training aid for simulating the actions of a magnetic compass under various flight conditions comprising: a pedestal; a compass wheel mounted for rotation about an axis on said pedestal; a first weight for imparting rotational force about said axis; support means suspending said first weight from a point on said compass wheel; a stationary guide member positioned between said first weight and said compass wheel; said support means engaging said stationary guide member whereby said rotational force is transmitted to said compass wheel but in an opposite direction; and a second weight secured to said compass wheel and positioned diametrically to the point of suspension of said first weight.
Claim 2
Dependent Claim
110 words
A training aid for simulating the actions of a magnetic compass under various flight conditions comprising: a pedestal; a compass wheel mounted for rotation about an axis on said pedestal; a first weight for imparting rotational force about said axis; support means suspending said first weight from a point on said compass wheel; a stationary guide member positioned between said first weight and said compass wheel; said support means engaging said stationary guide member whereby said rotational force is transmitted to said compass wheel but in an opposite direction; and a second weight secured to said compass wheel and positioned diametrically to the point of suspension of said first weight.
Claim 3
Dependent Claim
23 words
The combination set forth in claim 1, wherein said first weight is suspended by a flexible cord passing through said stationary guide member.
Claim 4
Dependent Claim
35 words
The combination set forth in claim 2, wherein said stationary guide member comprises a rigid rod, nonrotatably secured to said pedestal, having an eyelet formed in an end thereof through which said flexible cord passes.
Claim 5
Dependent Claim
53 words
The combination set forth in claim 2, wherein said stationary guide member compRises a rigid rod nonrotatably secured to said pedestal having an eyelet formed in an end thereof through which flexible cord passes, and including means defining a window, having a lubber line therein, mounted for pivotal movement about said compass wheel.
Claim 6
Dependent Claim
23 words
The combination set forth in claim 1, wherein said stationary guide member is nonrotatably secured to said pedestal and extends radially outwardly therefrom.
Claim 7
Dependent Claim
25 words
The combination set forth in claim 1, including means defining a window, having a lubber line therein, mounted for pivotal movement about said compass wheel.
