The time-to-arm (TA) and time-to-burst (TB) settings on the B83 bomb are located behind the access door on the aft assembly. This location is essential because it allows for safe and controlled access to the bomb’s critical settings without compromising safety or the structural integrity of the bomb. Accessing the settings in this specific area ensures that personnel follow proper protocols while maintaining operational security and safety during arming and detonation preparations.

Other locations mentioned, such as the nose assembly or the external casing, would not be practical for housing these settings due to safety considerations and the need to protect sensitive components from damage or accidental activation. Furthermore, the guidance system, while vital for the bomb's operation, does not directly govern the time-to-arm and time-to-burst functionalities, which are primarily related to the bomb's fuzing systems located in the aft assembly.
