Student pilots hear a lot about coordinated flight at the outset of training. It can’t be emphasized too much to the beginning student pilot that the flight controls, when applied in harmony, produce smooth maneuvers that guarantee safety and meet practical test standards.
“The pilot coordinates rudder pressure with aileron inputs to eliminate the effects of aileron drag (adverse yaw) during turns. And coordination during slow flight ensures that an inadvertent stall will not become a spin,” explained the Oct. 11, 2002, “Training Tip: Coordinated flight.” The lessons are clearly learned when the pilot can feel the slipping or skidding of uncoordinated flight—no longer dependent on instrument indications to sense its presence—and makes instinctive corrections.
For every rule there is an exception, and there are situations where intentionally uncoordinated flight—that is, flight with crossed controls—is needed. After all the necessary emphasis on coordination, learning to break the rule when appropriate can be a challenge.
That learning hurdle is best overcome with lots of practice, resulting in lots of confidence.
Slipping maneuvers are a case in point. Putting the trainer into an aggressive forward slip to lose altitude on a power-off or practice emergency landing is short on smoothness and coordination, but long on results.
“When performing the forward slip to lose altitude on final approach, the pilot lowers a wing with aileron and feeds in opposite rudder to prevent the aircraft from turning away from the approach course. The airplane's longitudinal axis is now positioned at an angle to its flight path, which increases drag and creates a higher descent rate on the approach,” explained the Feb. 24, 2006, “Training Tip: Forward slips, sideslips.”
“‘Sideslipping’ to handle a crosswind on final approach also requires holding a wing low and opposite rudder—but there is an important difference. The aircraft's longitudinal axis is kept aligned with the extended runway centerline.”
There are other situations, as when touching down in rough, gusty air, when you must do what’s necessary with the flight controls to maintain runway alignment (rudder) and avoid drift (aileron), even if the momentary result is flying cross-controlled.
Most of the time, smooth, coordinated control inputs exemplify correct technique and showcase your knowledge. Demonstrating how to break the rule correctly is another step along the road to your pilot certificate.

Question: I rent an airplane from my local FBO for my private pilot flight training. Is it necessary for me to have renters insurance?
Answer: While your FBO may not require it, having your own insurance coverage is strongly recommended. Here’s why: An FBO’s insurance policy is designed to protect the FBO, not the renter. You can be held liable for injuries to passengers, damage to property, and even damage to the aircraft itself. Also, if you damage the aircraft and the FBO turns in a claim for damage beyond its deductible to its insurance company, the insurance company can pay the FBO for the damage, and then take action against you to collect the amount it paid to the FBO. This is called “subrogation.” You also could be liable for the FBO’s deductible, which could potentially cost you thousands of dollars. With renters insurance available for less than the cost of a few hours of flight time, it only makes sense to get covered. The AOPA Insurance Agency provides renters insurance.

The Aircraft Owners and Pilots Association (AOPA) welcomed a Sept. 18 Federal Aviation Administration (FAA) announcement that it would host a “call to action summit” to address the barriers and potential challenges associated with equipping tens of thousands of aircraft for Automatic Dependent Surveillance-Broadcast (ADS-B) by the Jan. 1, 2020 deadline. ADS-B is a critical component of the NextGen air traffic modernization program.
