Intra-Vehicular Activity

During an Intra-Vehicular Activity (abbr. IVA) the player takes control of a Kerbal within a vehicle's command module. Vehicle handling works the same as if the vehicle were viewed from outside. One enter/leave IVA by either selecting "IVA" when mousing over the passengers of the vehicle, or pressing C to toggle.

Primary advantage of Interior View is the Altimeter within certain command modules. Rather than orbital altitude, it shows the vessels altitude above ground, taking mountains and valleys into account. This information can be especially helpful during landings on uneven terrain.

However, even though Intra-Vehicular Activity is implemented, the player can only interact inside, but cannot move a Kerbal. Squad Team has decided to improve in this a newer version.
