The helicopter crew are assisting Police Scotland Mountain Rescue Team at Stob a’ Choire Odhai, The Black Mount, north of Bridge of Orchy, where the rucksack was found.
Officers are appealing for information to help trace the owner.
The rucksack is a black Lowepro (30L capacity) and contains items of clothing, food and water. Other items found suggest it was being used by a photographer.
Sergeant Nigel McDonald said: "The bag has been at the summit since Saturday, 24 April. Police Scotland's Mountain Rescue Team together with support from the search helicopter and other specialist resources have been conducting searches of the area but have not yet traced the owner.
"We have not received any reports of missing people in the area however we are keen to trace the owner to ensure they are safe and well. If you are the owner of the rucksack, could you please contact police on 101, quoting incident number 1315 of 26 April."
