Tom,
I’m currently training with American Aviation at Manassas. It’s a good school with good equipment, however, they are short on CFIs. I’d recommend taking the list of questions that Chris posted in the FAQ section and go visit each school: https://airlinepilot.life/t/questions-for-any-prospective-flight-school/117
In addition to the questions about number of students/aircraft/etc., ask them to show you the scheduling system and look at the availability over the next several weeks. American Aviation has four daytime flight blocks per day. The last time block is 15:30-18:00. Therefore, you won’t be able to fly during the week with your current work schedule. I’m looking at their schedule right now and the weekend availability is few and far between. Ask Aviation Adventures the same question and see if the availability is any better.
For what it’s worth, American Aviation has hired multiple CFI’s in the last several weeks and the outlook is improving. However, these are questions you definitely want to ask before buying block time or one of the packages. Like Tory said, it might be better to wait until you can fully invest into an accelerated program which can ultimately save you time and money in the long run.
Good luck to you!
