All too frequently, I see pilots practice raw data hand flying in the aircraft (and reducing the safety margin) because they have a sim coming up.
Lets put it the other way around. If you never practice raw data flying. Do you think you will be able to manage when you need to fly raw data? Especially when stress levels are already high?
I reckon you never do manual landings either?????
I even practice raw data flying (when circumstances permit) when I have just done my sim.
