Abstract
Abstract A portable pilot aid device has a frame formed by two confronting members hinged together along one side thereof and resiliently urged together to form a clamplike structure adapted to receive a folded navigation map in any selected orientation so a particular selected flight path which the pilot is to fly is conveniently positioned be viewed by the pilot. The selected flight path on the map is positioned parallel to the path of movement of a power driven visible marker which represents the aircraft and moves parallel to the selected flight path on the map. Means are provided to adjust the speed of movement of the marker so its movement relative to the parallel flight path on the map corresponds to the movement of the aircraft over the ground. The marker is at a zero mileage point on a continuously moving endless belt which has mile markers formed thereon indicating the distance from the marker in miles to any point along the path of movement of the marker relative to the scale of the map involved. The pilot aid device is strapped to the pilots knee when in use to hold the chart in a convenient location in front of the pilot.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
195 words
A pilot aid device for receiving aeronautical maps to indicate to a pilot the approximate position of his aircraft along a given flight path represented on a particular map, comprising: a frame; visible marker means representing the aircraft supported on said frame for movement along a given path which simulates the flight path of the aircraft in which the device is used; manually controlled means for adjusting the position of said marker means to any position along said path; holding means for receiving and holding a selected aeronautical map in any one of a number of orientations where any one of a number of flight routes thereon to be flown between two points is clearly visible by the pilot and extends along said path of movement of said marker means; drive means connected to said marker means for moving said marker means along said selected flight route on the map at a rate relative to the map corresponding to a given ground speed of the aircraft; and means connected to said drive means selectively to adjust the rate of movement of said marker means so it corresponds to the actual ground speed of the aircraft.
Claim 2
Dependent Claim
195 words
A pilot aid device for receiving aeronautical maps to indicate to a pilot the approximate position of his aircraft along a given flight path represented on a particular map, comprising: a frame; visible marker means representing the aircraft supported on said frame for movement along a given path which simulates the flight path of the aircraft in which the device is used; manually controlled means for adjusting the position of said marker means to any position along said path; holding means for receiving and holding a selected aeronautical map in any one of a number of orientations where any one of a number of flight routes thereon to be flown between two points is clearly visible by the pilot and extends along said path of movement of said marker means; drive means connected to said marker means for moving said marker means along said selected flight route on the map at a rate relative to the map corresponding to a given ground speed of the aircraft; and means connected to said drive means selectively to adjust the rate of movement of said marker means so it corresponds to the actual ground speed of the aircraft.
Claim 3
Dependent Claim
58 words
The pilot aid device of claim 1 wherein there is associated and movable with said marker means a mileage scale with mileage indicating indicia increasing from zero in opposite directions from said marker means to indicate on the map the relative distances along the flight path from the aircraft to points both behind and ahead of the aircraft.
Claim 4
Dependent Claim
24 words
The pilot aid device of claim 1 wherein said marker means is a visible zero mileage reference point on a continuously moving endless belt.
Claim 5
Dependent Claim
49 words
The pilot aid device of claim 1 wherein said frame includes apaced apart members forming separable clamping jaws to receive an aeronautical map therebetween, said holding means including a portion of said spaced apart members which grippingly resiliently engage and holds the map inserted between said spaced apart member.
Claim 6
Dependent Claim
24 words
The pilot aid device of claim 4 wherein said frame members are platelike with the gripping portions thereof formed by mating edge portions thereof.
Claim 7
Dependent Claim
41 words
The pilot aid device of claim 1 wherein said frame includes a transparent platelike member forming the side of device which faces the pilot thereby allowing the pilot to see that portions of the map which is inserted into the frame.
Claim 8
Dependent Claim
51 words
The pilot aid device of claim 1 wherein said frame includes a writing surface thereon extending in the direction of movement of said marker means and adjacent thereto upon which the pilot can make notations of information to be used when the marker means moves in position next to the notations.
Claim 9
Dependent Claim
46 words
The pilot aid device of claim 7 wherein said writing surface is fastened to said frame by hinge means to allow the pilot to lift the writing surface out of the way to view a portion of the map which is located beneath said writing surface.
Claim 10
Dependent Claim
121 words
The pilot aid device of claim 1 wherein said frame includes a transparent platelike member forming the side of device which faces the pilot thereby allowing the pilot to see that portion of the map which is inserted into the frame and a spring clip mechanism secured to said platelike member to hold a sheet of paper to said platelike member which can be lifted out of the way without removing it from the spring clip mechanism to expose to the pilot the portion of the map which is otherwise covered by the sheet of paper. 10 The pilot aid device of claim 1 wherein said frame includes a storage compartment formed therein opposite the side thereof supporting the marker means.
Claim 11
Dependent Claim
27 words
The pilot aid device of claim 1 further including a calculator secured to said frame to assist the pilot in calculating the ground speed of the aircraft.
Claim 12
Dependent Claim
53 words
The pilot aid device of claim 1 further including a housing formed on said frame along the edge thereoF adjacent the selected flight route on the map, said housing having a transparent portion, and said marker means is positioned within said housing to be visible to the pilot through the transparent portion thereof.
Claim 13
Dependent Claim
60 words
The pilot aid device of claim 1 wherein said frame includes contoured means shaped to fit partially about the upper portion of a leg of the pilot and a strap and strap lock means fastened to said frame securely but removable to hold the pilot aid device to the pilot''s leg in front of him when in a sitting position.
Claim 14
Dependent Claim
