Final answer:

The standard time to wait before re-engaging a system after resetting a push button in the flight deck varies based on the aircraft's design, the system in question, and the manufacturer's guidelines, typically provided in the Flight Manual or QRH. Generally, 30 seconds to 1 minute is common for non-critical systems, while critical systems have specific procedures that must be strictly followed.

Step-by-step explanation:

The question of the standard time to wait before re-engaging a system after resetting a push button in the flight deck does not have a one-size-fits-all answer. The appropriate waiting time can vary based on the specific aircraft's design, the system in question, and the guidelines laid out by the aircraft manufacturer. The aircraft's Flight Manual or Quick Reference Handbook (QRH) typically contains the standard procedures and timings for resetting systems. A general rule of thumb, often employed for non-critical systems, involves waiting for about 30 seconds to 1 minute before re-engaging the system. This allows for any transient conditions that could have caused the issue to dissipate.

For critical systems, such as those related to the aircraft's control systems, engines, or flight instruments, there are often specific procedures that dictate not only the time to wait but also the steps to be taken before and after re-engagement. In these cases, adherence to the manufacturer's procedures is paramount for safety and regulatory compliance. Following an anomalous event or system fault, pilots are trained to consult the relevant manuals and follow the steps outlined, which include waiting times.

In some instances, there may be a built-in delay within the aircraft's systems to prevent immediate re-engagement. This is to ensure that any system protection logic has time to reset, or for the system to cool down or to complete self-tests before it is powered up again. Maintenance personnel and pilots alike are trained to understand the importance of these waiting periods, as premature re-engagement could lead to further issues or system damage.

In conclusion, the standard time to wait before re-engaging a system on the flight deck after resetting a push button depends greatly on the aircraft manufacturer's guidelines and the nature of the system itself. Always refer to the safety protocols and documentation specific to the aircraft in question.
