Abstract
Abstract The invention relates to an interlock between a ground based aircraft performance data storage system and an aircraft based indicator which monitors the performance of the aircraft during take-off and provides an indication of whether a safe take-off can be achieved at any given point in time. The interlock includes a punch-coded data card or the like onto which data determinative of acceptable levels of aircraft performance during take-off may be placed, stored and physically transported to the aircraft. This data is dependent on specific airport conditions, the particular type of aircraft, weather conditions, etc., and is computed by reference to such sources as the aircraft flight manual, a ground-based data bank and computer, meterological reports and data sheets for a specific airport. The aircraft is provided with an apparatus for receiving the record, decoding the data thereon to provide either an electrical or mechanical output and then utilizing this output to set the acceptable levels of performance into the take-off monitor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
In combination with an aircraft take-off safety monitor including means for storing desired values of at least one aircraft performance variable as a function of a different aircraft performance variable, means for comparing the actual said aircraft performance variable with the stored said aircraft performance variable, and means comprising one or more manually adjustable controls for setting into said storage means data at least partially determinative of said desired values of said aircraft performance variable: a. portable record means for storing said data, b. data transfer means responsive to said record means for transferring said data from said record means to said storing means by adjusting said controls to set said data into said storing means, and c. receiver means for receiving said record means and positioning same to permit actuation of said data transfer means.
Claim 2
Dependent Claim
