The first thing you need to understand is that it's not a scholarship, it's an avenue to help you secure a loan and a slot in a flight school where you shall study and attain the relevant ratings for you to secure a piloting job in KQ. The loan HAS to be repaid to Co-op Bank once you start working.
As for the application, please visit the Kenya Airways website careers portal, go to new jobs and click on the ab initio link which will take you to the application process. It's pretty straight forward. Please also take some time to read through the previous pages in this conversation (start from around 110), you'll find that most of your questions have already been answered.
