There are quite a few airports that we need added, even if just basic airstrips, to permit global exploration in smaller aircraft. This website has a pretty good interactive map showing all 24,000+ airports/airstrips available in FSX. Many of these are in the sim already but some, though existing in the real world, are not yet in MSFS. Would be nice if these two datasets could be compared and those missing, that are in the FSX database (that are at least still in Bing Map imagery (some are only in Google Earth) could be pegged to be added in later updates.
A few of these added will help get you across the seas in smaller aircraft because they make some destinations come into fuel range:
For those trying to explore the South Pacific, more destinations would be ‘reachable’ without role playing turning cargo into fuel tanks:
And flying in the Indian Ocean, you can more easily reach Africa with this many options:
And even some of the extremities of the world can be reached, with a few additions, such as these at the tip of Antarctica and South America:
