V Formation
This formation, by far, is one of the most used. Of course, as with any formation, it comes with advantages and disadvantages though the former outweigh the latter by volumes. Advantages of this wing formation are:
1. The Wingleader is able to see and follow the line of Thread
2. The larger dragons are able take down brunt of Thread, leaving the smaller and more agile dragons to char any clumps missed that may be blown out of the main path.
3. The formation itself is easily stackable and varied, making it the second most desired formation to use.
Disadvantages:
1. The Wingleader and Wingseconds can't see what's going on behind them without taking their eye off the leading edge (though with an experienced group, this is not a problem, per se.)
2. Verbal communication is next to impossible, though draconic communication and hand signals are not hindered. This formation works well for any group with a Wingleader that is comfortable with working with remote signals. It also works well with weyrling wings, as judging the space between positions is easily done. The formation goes as follows:
The Reversed or Inverted V Formation
This formation is the complete opposite of the V formation. The disadvantages for the V formation are mostly eliminated. The Wingleader is able to see his riders, though draconic communication still is the best means and hand signals as well as verbal communication are close to nil as the wingriders can not see their Wingleader. All the advantages of the V formation are still in use, as the Wingleader and his Wingseconds are able to see the line of Thread, the larger dragons meet Thread first, letting the more agile dragons maneuver in between, and weyrlings are still able to judge the space between themselves and their wingmates easily.
