Can I be a pilot with light form asthma?
All medical issues must be cleared by an AME (aviation medical examiner). If you have questions about potential problems it’s best you consult one near you. That said I know a number of pilots with asthma so it is possible.
Honestly, I am not sure. Schedule an appointment with a FAA Medical Examiner for a first class medical. They will be able to answer your questions.
It’s not impossible but it will take some time and frustration. Depends on your situation.
Make sure you have a good AME and understand the process.
