I was giving a stage check to a pilot who had just soloed the day before and I asked him to do the "turn around a point" maneuver. He flew a great maneuver, but he had no idea why it was a good thing to know.
You do not have to be an Instrument Flight Instructor (CFII) to give instrument flight instruction? No, the only time a CFII certificate is required is when a person is training for the instrument rating. Initial instructors give instrument training all the time.
Every flight you will ever take consists of a series of decisions -- it's the quality of those decisions that determine the level of your safety. Unfortunately many pilots take decision making for granted.
The following is an airspeed maneuver example of how the real-world element can be a part of everyday flight training, with the goal being not only to train as a pilot but to train to become Pilot in Command.
Flying away from the friendly confines of your home airport offers another great flying challenge. It also offers an unlimited number of "what if" scenarios. When the airlines use "LOFT" scenarios, they are always playing out a flight going to somewhere (LOFT is Line Oriented Flight Training -- Line, as in flight line or route). Creative instructors and inquisitive students can "war game" cross counties forever. Here is just one and it's a true story.
