Emergency drills

Each drill puts you in trouble and checks what you do. Read the handset and the HUD, then act with the controls under it.

Cell 3 cannot read above 1.0

The loop leaks (it fails both leak tests)

A CO₂ sensor is fitted

In the 3D window: drag to turn the unit, scroll to zoom, click a part to read about it. Coloured dots show the gas: CO₂-laden, scrubbed, O₂ added, diluent.

No-stop time while you have one; once in deco the handset shows TTS (ascent at your ascent rate plus every stop) and the first stop, like the AP. Planned on your setpoint (following the auto switch) and the loop's current N₂/He mix. GF 85 reproduces the ceilings and TTS in real AP logs to within a metre and a few minutes.

Buoyancy

Net lift: 0.0 kg
Vertical speed: 0 m/min
Gas in wing: 0.0 L
Finning: 0 %

On a CCR, breathing doesn't change buoyancy: gas just moves between your lungs and the counterlungs. What changes it is the amount of gas in the loop and the wing, and both expand as you go up.

Gas supply

O₂ (3 L, in the case)200 bar

Diluent (3 L, in the case)200 bar

Offboard bailout (S80, 11.1 L)200 bar

Temp-Stik sensor

Axial flow: gas goes down the centre tube and back up through the bed, so the used band climbs from the bottom. The reaction is hot, which is what the Temp-Stik follows.
