Use "no entry" gates to prevent arriving passengers (from flights) from walking back into the security checkpoint 1.2.1.
A core challenge is that different machines process passengers (PAX) at different speeds. Planning around the slowest unit—the or Body Scanner —is the standard strategy.
: ~20–25 pph (Body scanners are slower and generally not recommended for high-volume lanes unless required). ID Check Stand : ~29–32 pph
Equipment (ID checks, scanners) must face the correct direction, leading passengers toward the gates 1.2.1.
These three devices form the foundation of your checkpoint, and how you arrange them dictates your entire airport's efficiency. However, you can't just plop them down anywhere. Your Security Zone must be indoors and create a true "secure area" behind it.
Be aware that scripts can sometimes fail upon loading a saved game, causing sudden "blobs" at scanners even in verified layouts. Recalculating lanes or restarting the game often fixes this. Building ADVANCED SECURITY — SimAirport (#4)
Do this test:
The game will give you a green check when you place a small fence line with one ID checker and one metal detector. But getting the for high throughput requires you to ignore the minimum and aim for the engineered maximum.
