Your Family tree is wrong. Aegon the 5th is the Mad king's grandfather, not his father.
- Bother to read articles before commenting on them: see "Aerys II Targaryen#In the books": "In a minor change from the books, Aerys II is said to be the son of King Aegon V Targaryen, rather than his grandson. His father, Jaehaerys II, appears to have been eliminated from the roll of kings. The reason for this appears to be to simplify the relationship between Maester Aemon - Aegon V's older brother - and the other Targaryens (by making Aemon Daenerys' grand-uncle, rather than great-grand-uncle).
