It seems to me that the real beneficiaries of this are people currently flying on an SI or healthy people that wouldn't have a problem getting a medical. This really does very little to get people who have been sitting on the sidelines back in the cockpit. Truly a disappointing outcome after an exhaustive wait.
Chapter 8 of the AC has requirements for an SI while using BasicMed for 3 medical categories:
8.2 Special Issuance Medical Certificates Required. For certain conditions, a person wishing to exercise BasicMed must complete the process for obtaining an Authorization for special issuance of a medical certificate in accordance with § 68.9. The person is required to obtain only one special issuance medical certificate for each condition, and may subsequently exercise BasicMed. Persons who have, or are newly diagnosed with, a cardiovascular, neurological, or mental health condition described in FESSA, may not use BasicMed until they have been found eligible for special issuance of a medical certificate. Once issued a medical certificate, the person may then use BasicMed if they meet all other requirements of FESSA. These conditions are listed below:
8.2.1 A mental health disorder, limited to an established medical history or clinical diagnosis of any of the following: 1. Personality disorder that is severe enough to have repeatedly manifested itself by overt acts. 2. Psychosis, defined as a case in which an individual: • Has manifested delusions, hallucinations, grossly bizarre or disorganized behavior, or other commonly accepted symptoms of psychosis; or • May reasonably be expected to manifest delusions, hallucinations, grossly bizarre or disorganized behavior, or other commonly accepted symptoms of psychosis. 3. Bipolar disorder. 4. Substance dependence within the previous 2 years, as defined in part 67, § 67.307(a)(4).
8.2.2 A neurological disorder, limited to an established medical history or clinical diagnosis of any of the following: 1. Epilepsy. 2. Disturbance of consciousness without satisfactory medical explanation of the cause. 3. A transient loss of control of nervous system functions without satisfactory medical explanation of the cause.
8.2.3 A cardiovascular condition, limited to a one-time special issuance for each diagnosis of the following: 1. Myocardial infarction. 2. Coronary heart disease that has required treatment.3. Cardiac valve replacement. 4. Heart replacement.
