I believe it is very unfortunate that Asperger syndrome has been included on the autism spectrum even if labeled "High Functioning…. "
I have personally worked with numerous Aspergers clients. They are capable of doing anything anyone else can do. Their weakness in understanding nuanced speech patterns, and weakness in understanding people's true intent, Etc can easily be overcome by spending time with a professional in a certain area who can teach them the typical words and phrases that are used in that field and what they really mean.
When people with Asperger syndrome do inappropriate things or say inappropriate things, they are not trying to be inappropriate. They will listen with very wide open ears to people who will actually teach them what the appropriate expectations are in different situations. I also happen to be a pilot, and my son is an airline captain. I have no doubt in my mind. A person with Asperger syndrome can become an excellent pilot. Before you go for your FAA physical, sit down with someone who can help you practice for the physical. Practicing means hearing the doctor's questions, following through with the tasks he requests, and not saying inappropriate things. There is absolutely no reason to tell the FAA doctor anything about your Asperger diagnosis.
Just like if you have a problem, where you got only A's in Calculus, but have a mental block against differential equations. You may think that that is a math disability, but it is irrelevant for most jobs. Therefore it would be foolish to write on your resume, or tell an interviewer anything about your math disability, especially when the job does not require differential equations.
"Disclosing" your "math disability" will make the interviewer think you can't do basic math. He will not understand that you completed at least 3 semesters of Calculus in university, and only tripped on a higher-level calculus!
The problem with their throwing out Asperger's as a separate diagnosis and putting everyone into the "Autism Spectrum" is that Aspys are not autistic in the sense that most understand the word.
It is a very limited syndrome. Basically Aspys understand perfectly well everything said that is clearly expressed. They only miss situations where they need to "hear" the emphasis the speaker places on a word or phrase to understand the speaker's intent.
That is much less common in flying, since most of our communications are with short words or phrases that you will be clearly taught in flight school.
This is done so the foreign airline pilot whose "American English" is likely not their first language, can understand without confusion.
Sadly, the new inclusion of Aspys onto the Autism Spectrum causes many well-meaning people to assume people with Asperger's have some of the other autism weaknesses. Even many Aspys have read up on "the spectrum" and assume incorrectly that they have some of those characteristics.
So, absolutely first get your Class 3 medical, and get, in this order:
Get some good hours, maybe 200, really master the special language of Aviation, then make up your mind.
Get your CFI maybe, so you can earn some money instructing, while building hours instead of paying for every damn hour
Go get your Class 1 medical.
Then, GO FOR IT
