Consider the following statements with respect to Intelligent Flight C...
Statement Analysis:
Let's analyze each statement one by one:

Statement 1: It is developed by NASA.
Statement 2: It is used in NF-15B aircraft.
Statement 3: The IFCS Generation-I flight was first tested in 2003.
Statement 4: An artificial neural network is used in this control system.

Explanation:
Statement 1: It is developed by NASA.
The Intelligent Flight Control System (IFCS) is not specifically developed by NASA. It is a general term used to describe advanced flight control systems that incorporate intelligent algorithms and technologies.
Therefore, statement 1 is incorrect.

Statement 2: It is used in NF-15B aircraft.
The NF-15B aircraft is a modified version of the F-15B Eagle aircraft used for research and development purposes. It has been used by NASA and other organizations for various flight experiments and testing. While it is possible that an Intelligent Flight Control System (IFCS) could be used in the NF-15B aircraft, the statement does not provide enough information to confirm this.
Therefore, statement 2 is ambiguous and cannot be determined as correct or incorrect.

Statement 3: The IFCS Generation-I flight was first tested in 2003.
The statement mentions the testing of the IFCS Generation-I flight in 2003. However, there is no specific information available to confirm or refute this claim. Without any supporting evidence, we cannot determine the accuracy of this statement.
Therefore, statement 3 is ambiguous and cannot be determined as correct or incorrect.

Statement 4: An artificial neural network is used in this control system.
An artificial neural network (ANN) is a type of computational model inspired by the structure and functions of biological neural networks. ANNs have been widely used in various fields, including aerospace engineering, for tasks such as control systems, pattern recognition, and optimization. It is possible that an ANN could be used in an Intelligent Flight Control System (IFCS) to enhance its capabilities and performance.
Therefore, statement 4 is plausible and could be correct.

Conclusion:
Based on the analysis, statement 1 is incorrect, statement 2 and 3 are ambiguous, and statement 4 is plausible. Therefore, the correct answer is option 'C' - 1, 2, 3, and 4.
