Not so fast FNG. Just wait until the hazing starts!

Don't haze me bro!

Scotty how many hours you fly in the last six months?

Probably close to 500. I work as a CFI at one of those 141 schools with nothing but foreign students. I have about 8 students now who all want to fly every day so if the weather is good I usually get 7 hours of flight time a day.

In training at Mesa- great instructors and atmosphere. I've passed all tests and orals so far.
However now I'm in cockpit procedures training in prep for sim training. However I cannot memorize and "get" flows and callouts. I've always been a single pilot so I've never had to deal with the crew concept.
I don't know if I should proceed into sim and risk flunking and hurting my career... or quit one and go back to single pilot ops.

If you want to advance your career, even in single pilot ops, you better get used to memorizing flows and callouts. You'll have to do this getting type ratings and other stuff, even if it's for single-pilot ops. Although you might be aided by a checklist in some cases, you have to know what you are doing and the flow, otherwise you spend too much time hunting and trying to figure stuff out. This is one of the benefits of the more structured 141 schools, but you can do this on your own as well. Practice, practice, practice. Visualize, practice. Are you writing these flows down? How much time is spent doing it? It may seem insurmountable, but I guarantee the next ones you learn will be much easier and you'll see that it IS possible to learn flows.

Is that you, JB? It'll come with time and repetitions. Many, many repetitions. I can already tell you're not practicing with your sim partner enough, but you already knew that.

I can guarantee you had your own flows flying single pilot, even in a 172 or an Aztec with holes in the bottom and sides. ;-) This is just a different set of flows. It'll come, but you gotta put in the effort and I guarantee no one in your class is practicing them enough.

#1 pro tip- flows are basically your required actions on the following checklist.

#2 pro tip- don't memorize each profile as individual events. Memorize normal takeoff/arrival/approach then memorize only what's different about the emergency ones.

Just a friendly piece of advice: Quitting your job may not hurt you, but it also doesn't help. If you intend on continuing on with 121 somewhere down the line, you will have to explain why you didn't complete training - what will you say? Think about it.

Far better to give your current situation 150% and pass, rather than resign just because you aren't "getting it". Flows and such can be challenging for someone who is used to single pilot, however if you practice, just like everything else, it becomes like second nature.

Better to try for something and get part of it than to try for nothing and get all of it. I would suggest that you ask yourself if you have truly done everything you can to succeed before resigning. If the answer is "yes" and you still don't feel you're going to make it and you resign, at least you did so with a clear conscience
