During an Intra-Vehicular Activity (abbr. IVA) the player takes control of a Kerbal within a craft's command pod.

To start an IVA, go to the exterior (default) view of a manned spacecraft, then mouse over the images in the lower right corner and press the IVA button, or press C to toggle between exterior view and IVA. The primary advantage of IVA is the radar altimeter within certain command modules. Rather than altitude above sea level, it shows the craft's altitude above ground level (abbr. AGL), taking mountains and valleys into account. This information can be especially helpful during landings on uneven terrain.

However, Intra-Vehicular Activities are only partially implemented, meaning that there are few possibilities to actually interact with the interior. So far it is possible to:

• look around and read the instruments (right and middle mouse button),
• look through the windows (double-click on window),
• control throttle level by moving the throttle lever up and down (click and drag it with the mouse cursor),
• switch the reference of the speed indicator (click on green button next to indicator),
• control the craft using the key bindings of the exterior third-person view.

Monitor with only staging enabled

The example above shows an altitude of 2000 meters.

When going into the IVA mode, most of the HUD will disappear and the control panel inside the cockpit will be visible instead. Most of the instruments on this new control panel are easy to understand. While the instruments are having the same appearance in all available IVAs, the layout differs.

• Roll, Pitch and Yaw: The roll, pitch and yaw indicators look similar to and work just like the ones in the normal game HUD.

• Monitor: The monitor shows things that can be difficult or impossible to see from inside the vehicle, such as the state of SAS or RCS, or the ability to separate a stage. Green lights indicate the corresponding system is currently activated.

• Speed: This indicator displays the speed in meters per second (m/s), and can be switched between orbital speed, speed relative to the surface or relative to the target.

• Navball: The navball looks and works exactly as the normal navball. However, in IVA mode you can zoom in on the navball, allowing precision alignment difficult to accomplish with the third person interface.

• Atmosphere: This gauge displays the atmospheric density. It is identical to the corresponding display in the third person interface.

• Height: The Altitude (or Height Monitor) shows the craft's current height above sea level. This information is displayed in analog form familiar to airplane pilots. However, unlike airplane altimeters which work on air pressure, this one works even the cold dark hard vacuum of space. How does it do this? The magic of electronics!

• Radar Altimeter: While normal altitude indicators display altitude above (mean) sea level (abbr. ASL or AMSL), the radar altimeter displays the craft's height above the ground. This information is not displayed on the third person interface, which means that IVA landings have a unique advantage. The advantage is offset by the fact that the third person view can swivel freely, affording a more comprehensive view of the surface than the IVA perspective.

• Vertical speed: The vertical speed is shown in meters per second (m/s) on a gauge similar to the one on the HUD.

• Angle: This gauge displays the craft's heading.
