During orientation flights the bees will begin by just walking over the front of the hive, they might even walk all the way around it. A few days later they begin to make flights, a few inches, a few more inches, a foot, another foot, until they are 50 feet or more from the entrance before returning to the hive.
In a bee yard with a dozen hives, between 2-4 pm on a warm summers afternoon, the sun can appear to be blocked by the cloud of bees. Between the returning foragers and the orientation flights it can appear as if a swarm were taking flight from each hive.
In a hive, as the population increases, the graduating class gets bigger and bigger until the queen reaches here maximum ability to produce brood, then the orientation flights will remain relatively constant. But a hive with 2 full brood boxes and 3-4 supers can put a lot of bees into the air at one time.
