(singular) of “unexplained” (it’s explainable lol, just not in the physician notes) syncope in my medical history.
Sounds like you've already read the waiver guide:
p119.
"10.9 SYNCOPE;AEROMEDICAL CONCERNS: Loss of consciousness in flight. WAIVER: A waiver is not required for simple episodes of vasovagal syncope, with known precipitating causes such as pain or the sight of blood.... A waiver is necessary for unexplained syncope, recurrent syncope, syncope associated with pathology (e.g. cardiac conduction or valvular defect), syncope with LOC > 1 minute, delay in recovery of normal function > 5 minutes, or G-LOC > 18 seconds, or syncope associated with convulsions lasting over 6 seconds. Non-waiverable situational syncope includes cough-, postural-, Valsalva-, and exertion-induced syncope. Other types of syncope with be considered for waiver on a case-by-case basis"
Waiver chances are based on individual conditions, not a blanket term.
I've touched on it a couple of times on the forum:
1. MEPS docs are not NAMI docs. They generally cannot speak on the medical requirements for a flight physical.
2. The NAMI physical is incredibly daunting and it's easy to spook yourself reading anecdotal experiences on the forum. Its a lot of uncertainty and a big barrier to entry into something you want to do.
3. A vast majority of NAMI Whammies are related to eyes. Most other conditions are waiverable.
4. Agreed with the comment above. Bring multiple copies of your medical records with you. They will lose them and ask for them again.
Good luck.
