What is the interplanar spacing between planes?
What is the interplanar spacing between planes? The interplanar spacing dhkl between adjacent planes having Miller indices (hkl) is defined as the distance between first such plane from a parallel plane passing through the origin.
How close can two planes fly to each other?
What is the distance for flying aircraft set by the regulations? Commercial aircraft flying below 29,000 feet must maintain a vertical separation of 1,000 feet. Any higher and the separation increases to 2,000 feet, except in airspace where Reduced Vertical Separation Minimum (RVSM) applies.
Why do planes avoid flying over oceans?
Since it is preferable to crash land on solid ground, and ideally close to an airport where emergency services are accessible, most airlines prefer to fly over land. Most flights are intended to spend as little time as possible over water, since storms are more common over the ocean than on land.
Do planes fly past each other?
If you are a frequent traveller who enjoys a window seat, you might have noticed other aircraft while in air. Flying in the crowded skies over Europe or North America, it is quite common to see other aircraft whizzing past, either above or below.
