SHARING YOUR AIRSPACE


You have learned the correct method for safely entering the traffic pattern at nontowered airports, and you've studied right-of-way rules that keep different categories of aircraft safely separate. (See the May 2, 2003, "Training Tips" on right-of-way rules.) Now you're ready to put these concepts to the test as you endeavor to operate safely in the presence of other airport users.

After you check airport publications for your destinations' radio frequencies, runway lengths and bearings, and facilities, be sure to look up what other kinds of air traffic might be present. "To airplane pilots, the ways of helicopters, gliders, and balloons seem mysterious. Knowing how they come and go helps you to coordinate your departures and arrivals with theirs. Being familiar with their operation is comforting when you scan for traffic because you know where to look for them.

Towplanes and gliders may use only the runway that is closest to the glider operation's base; you may need to use another because of reported surface winds. Large airplanes may use only the longer runways and fly a higher traffic pattern. Parachute jumping could be under way; what frequency is used to advise local aircraft about "jumpers away"? Helicopter pilots are responsible for avoiding the flow of fixed-wing aircraft, but keep an eye out for them in the pattern and while taxiing. Instrument approaches flown for practice by pilots training for the instrument rating could be in progress. These aircraft train with different arrival routes than aircraft making routine arrivals under visual flight rules. Ask your instructor to describe instrument training that could be in progress and what to listen for on the common traffic advisory frequency (CTAF). If there is a floatplane base on an adjacent body of water such as a river or lake, visualize its traffic pattern. Does the seaplane base use the same CTAF as the airport?

Experience will make these other kinds of aviation activity more familiar. Meanwhile, do your research and ask questions to fill in the gaps.
