Abstract
Abstract An aircraft banking angle indicator which includes a banking angle sensing arrangement for generating an actual banking angle signal, a maximum banking angle input device for manually entering a selected maximum banking angle, a signal processing arrangement having respective inputs connected to the banking angle sensing arrangement and to the maximum banking angle input devices for generating an excessive banking output signal indicative of a banking angle exceeding the maximum banking angle, and an indicating arrangement having a signal input connected to the banking angle output signal for indicating the excessive banking angle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
94 words
A banking angle indicator for an aircraft comprising banking angle sensing means for generating an actual banking angle signal, maximum banking angle input means for manually entering a selected maximum banking angle, signal processing means having respective inputs connected to said banking angle sensing means and to said maximum banking angle input means for generating an excessive banking angle signal indicative of an actual banking angle exceeding said selected maximum banking angle, and visual indicating means having an input connected to said excessive banking angle signal for visually indicating presence of excessive banking angle.
Claim 2
Dependent Claim
94 words
A banking angle indicator for an aircraft comprising banking angle sensing means for generating an actual banking angle signal, maximum banking angle input means for manually entering a selected maximum banking angle, signal processing means having respective inputs connected to said banking angle sensing means and to said maximum banking angle input means for generating an excessive banking angle signal indicative of an actual banking angle exceeding said selected maximum banking angle, and visual indicating means having an input connected to said excessive banking angle signal for visually indicating presence of excessive banking angle.
Claim 3
Dependent Claim
43 words
A banking angle indicator according to claim 1 including aircraft attitude control means in said aircraft having an input connected to said excessive banking angle signal for automatically restoring the aircraft banking angle to a value no greater than the maximum banking angle.
Claim 4
Dependent Claim
49 words
A banking angle indicator according to claim 2, including a gyro with an axis disposed substantially in a plane perpendicular to the axis of the aircraft in said banking angle sensing means, and electronic reading means coupled to said gyro for reading said banking angle signal from said gyro.
Claim 5
Dependent Claim
19 words
A banking angle indicator according to claim 3 wherein said gyro is a part of an aircraft turn coordinator.
Claim 6
Dependent Claim
20 words
A banking angle indicator according to claim 3 wherein said gyro is a part of an aircraft flight director system.
Claim 7
Dependent Claim
50 words
A banking angle indicator according to claim 3 wherein said actual banking angle signal is an analog signal analogous to the actual banking angle including an analog-to-digital converter in said signal processing means for converting said actual banking angle signal to a digital signal indicative of said actual banking angle.
Claim 8
Dependent Claim
37 words
A banking angle indicator according to claim 6 including an analog-to-digital converter in said maximum banking angle input means for converting said selected maximum banking angle to a digital signal indicative of said selected maximum banking angle.
