The profit rate assumes 105-130 kills per hour. Your actual profit may be higher or lower depending on your speed, level, gear, etc.
Aviantese drop four noted adamantite bars fairly commonly (about 1 in 4 kills), but players must have completed the hard Fremennik Diary in order to get the bar drops noted. This makes killing them fairly profitable, as each kill will on average give one adamantite bar. They also drop rune daggers and runite limbs, which can be alched, but the bulk of their profit comes from adamantite bars. Because they are noted, it means you can stay indefinitely if you aren't in need of food.
Depending on whether you have Bones to Peaches or not, once you run out of food or you're finished, teleport out and sell your adamant bars and other items on the Grand Exchange.
