For your consideration ...
Initial rotary wing flight training in the Army, while either a warrant officer or commissioned officer, is broken into four phases that total 32 weeks with 179 hours of flight instruction. 60 of those hours of flight time are a training helicopter, the TH-67 Creek. 30 hours are in a flight simulator. Training is completed in the OH-58. After this training, graduates move on the Advanced Graduate Flight Training to become specialized in the AH-64A, AH-64D, CH-47D, or UH-60A. All training, basic and advanced, adds up to about 55 weeks of total training before gradating and then going off to a regular assignment.
So say she's flying for 4 years total after graduating. She served about 5 years, after joining in 2019. With about 450 total flight hours, that leaves about 271 of total flight hours in the Blackhawk, or about flight 68 hours per year. Which is abysmal.
In the Army, for standard training & garrison operations, the typical yearly flight time is around 150–200 flight hours per year for active-duty pilots. For those 4 years post training, she should have accumulated at least 600 hours of flight time. So she was behind on her flight time, because of doing other things at the White House not related to flying. Also, there is absolutely no way she was a PIC, Pilot-In-Command, with those low flight hours. If she was in the left seat, as the majority of pictures show, she was the co-pilot. Pilot and co-pilot seats are reversed in helicopters. She was possibly getting a nighttime check flight.
Also, Army officers are eligible for promotion to captain 4 years after commissioning, perhaps she was promoted to captain possibly due to DIE factors?
