Dutch driver Joey Alders won the Asian F3 title for 18 super-licence points, with Red Bull junior driver Jack Doohan, son of five-times 500cc motorcycle champion Mick, runner-up and Russian Nikita Mazepin third.
No woman has competed in Formula One since 1976, but Chadwick, a development driver for the Williams team, is raising hopes that she could be the one to end that long absence.
She will also drive an all-electric Jaguar Formula E car at a rookie test in Marrakesh, Morocco, on March 1.
Separately, the W Series announced on Sunday that its 2020 drivers will undergo a training programme with the help of experts, including retired Olympic heptathlon gold medallist Jessica Ennis-Hill and snooker champion Jimmy White.
White, the current snooker world seniors champion, will “demonstrate the art of concentration and precision", series organisers said.
The first race of the W Series season is in St Petersburg, Russia, in May.
