At last we get there....... the sim is the right tool for the job. No weather delays yet you can dial in any kind of bad weather should you feel the need. You can choose the time and place and monitor the candidate under realistic CRM conditions.
When we get enough simulators (in the right places) there will be no excuse for not doing it properly. By all means check-out the handing skills in the aircraft but any kind of night or IMC training will benefit from this artificial by highly realistic environment.
