A senior official of the Board said Chappell, who is due to reach Lahore next month, would be helping out the Board in many ways.
"His role will not be restricted to the National Cricket Academy. He will be having a look at the Pakistan senior and 'A' team players in the camps and will then prepare suggestion papers for their team management," he was quoted as saying by local daily The News.
Clarifying that Chappell would not be infringing on the authority or domain of the team management, the official said his role would be advisory in nature.
"He will give his suggestions and advice to the Board which will decide how to act upon those in the best possible manner," the official added.
The PCB has signed Chappell on a contract that entails that the former Australian captain would have to devote 30 days in a year to his assignment and it is up to the Board how they utilise his services.
The official, however, dismissed reports that Chappell was being paid around $ 5,000 per day for his contractual period. "The amount being quoted is rubbish. It is much lower than that I can assure you that. In fact I think we have got his services for a very reasonable amount given what others charge for coaching assignments these days," he said.
The official also said Australian bowling coach Daryl Foster, slated to reach Lahore on June 24 for a 16-day assignment, would similarly be helping out in various ways without interfering with the Pakistan management.
