Have you ever wondered what the aircraft marshallers’ hand signals mean when you are taxiing up to an FBO? These industry standardized hand signals are used for one-on-one visual communication between your pilots and ground operations personnel. Each one represents a phase in coordinating pre- and post-taxi procedures. You can see from the image below that there are quite a few signals, which cover instructions from starting the engine to moving the wheel chocks. These visual exchanges between cockpit and the ramp supplement radio communication with air traffic control, adding another level of safety and efficiency to each of your PlaneSense® flights.
