-Except for the RPM IVA upgrade patch, all of these IVAs require the ASET Props and Avionics packs.

 * Module Manager patches are included that upgrade the basic RPM props to MAS-equivalent props.  This patch allows the RPM IVAs included in RPM to use MAS instead.
 * The stock Mk 1 v2 Command Pod (pictured above) demonstrates a retro-NASA style IVA suitable for suborbital or short orbital flights.  A flight manual is available [on the wiki](https://github.com/MOARdV/AvionicsSystems/wiki/Operations-Manual-Mk1).  This is a fully-featured IVA.
 * The stock Mk 1-3 Command Pod includes a retro-NASA IVA for the center seat. This IVA *is not* complete, but it is a starting point if someone else wants to finish it.
 * The stock Mk1 Lander Can by snakeru, a conversion of the [ASET Mk1 Lander Can](https://forum.kerbalspaceprogram.com/index.php?/topic/156131-mk1-lander-can-iva-replacement-by-aset11/).  Note that if RasterPropMonitor is installed, the MAS version of the IVA is switched off.  You must uninstall the ASET IVA to use the MAS IVA.
 * The MRK DM command pod, previously part of the [Commonwealth Rockets](https://forum.kerbalspaceprogram.com/index.php?/topic/164365-13-commonwealth-rockets-tea-powered-spaceflight-in-development/) mod.
 This command pod demonstrates a modern partial-glass cockpit design good for activity around Kerbin and its moons.  This pod has moved to a different mod, and I have not tested to see if the patch still works.

 For some additional IVAs, the Flapjack cockpit in the [Kerbal Flying Saucer](https://forum.kerbalspaceprogram.com/index.php?/topic/173857-14x-pre-release-live-kerbal-flying-saucers-build-flying-saucers-in-ksp/) mod shows a glass cockpit design.
