It may be a little early to answer this question as the QOS is not yet ready for FSX but i was wondering if the shared cockpit/aircraft feature will be possible with the 747 QOS and future PMDG aircraft with full functionality available to the 2nd pilot? or possible at all?If so it will certainly enhance the whole experience in its realism,thanksFynn

There's is absolutely no documentation available on this feature in the FSX SDK. If/when MS provides such documentation, we'll evaluate the feasibility of implementing it...
