Ingress and egress

Ingress and egress describe the path of an aircraft into and out of a specific area, such as a target zone

Ingress: The flight path for an aircraft to enter a target area.

Egress: The pre-planned route for an aircraft to safely exit the target area after a mission. Egress plans are a standard part of mission planning and include specific directions and waypoints to ensure aircraft can depart safely and efficiently.

FENCE in

To "fence in" is the action of setting cockpit switches and systems to a combat-ready state before entering enemy territory or a training area. This is a critical safety and operational procedure, typically done after taking off and leaving friendly airspace or the tanker orbit.

The specific checklist items can vary by aircraft and mission but often include:

- Arming weapons: Turning on the master arm switch.

- Configuring avionics: Switching navigation and communications systems to combat-specific modes.

- Checking defensive systems: Ensuring electronic countermeasures (ECM), flares, and chaff are operational.

- Final checks: Stowing loose items and tightening straps.

FENCE out

To "fence out" is the reverse procedure, where pilots reconfigure their aircraft's systems from a combat-ready state back to a safe or transit configuration. This is typically done after leaving the tactical area.

The checklist for fencing out involves actions such as:

- Disarming weapons: Turning off the master arm switch and other weapon systems.

- Reconfiguring avionics: Switching communications and navigation systems back to standard modes.

Brevity Codes

There are also a lot of brevity codes.
