When flying dual, how should the ISS be configured for ejection?

The correct configuration for the ISS (Inter-seat Sequencing System) when flying dual is to set it to BOTH, allowing either pilot to initiate dual ejections. This configuration enables flexibility and quick response in emergency situations, as it allows both pilots to egress the aircraft simultaneously in the event of a critical failure or emergency.

When the ISS is configured to BOTH, it ensures that the ejection seats are connected in such a way that if either pilot pulls their ejection handle, both seats will eject together. This is crucial in maintaining safety and ensuring that both pilots can evacuate safely without waiting for one to be designated as the primary initiator of ejection.

In contrast, other configurations such as SOLO would limit the ejection capability merely to the pilot who is designated as the solo operator, which is not ideal in dual operations. By using the BOTH setting, the T-6B ensures that both crew members can respond to emergencies in the most effective manner.
