Uncoordinated Flight

Gemini Sparkle

Key Takeaways:

  • Slips are intentional maneuvers, such as forward slips to lose altitude or sideslips for crosswind landings, which increase drag by flying with the aircraft's longitudinal axis unaligned with the direction of flight, and are generally safe when properly executed.
  • Skids are unintentional and dangerous flight conditions where the bank angle is too shallow for the turn, making a stall in a skid significantly more hazardous as it can rapidly progress into a spin.
  • Maintaining coordinated flight ("keeping the ball centered") is crucial to avoid unintentional slips and skids, which are primary contributors to stall/spin accidents, especially at low altitudes where recovery time is limited.

Has this ever happened to you? You’re in the traffic pattern and trending high on final. The throttle is at idle and the airplane is fully configured to land. Initially there may be a temptation to push the nose down, but the extra airspeed will probably lead to significant float. Staying on the current approach path will lead to a landing farther down the runway than we would prefer. Going around is always an option, until it isn’t.

If you are already one step ahead of me, give yourself a gold star; yes, we’re talking about slips. The first time I attempted a forward slip, I had to fight the voice in my head that was upset the ball was not centered. When I was first practicing the steps of a crosswind landing, I knew that aileron needed to be into the wind and opposite rudder was required to align with the runway. It took a bit of ground instruction to make the connection that this was also a slip. Let’s hop into a quick refresher on slips and their much less useful friend, the skid.
