Airport infrastructure
The home airport: It's the corner of the aviation universe that a student pilot knows best. Runway bearings, lengths, and widths; radio frequencies, traffic pattern altitudes, and directions—even airport quirks—are home-field facts that most pilots can recite by heart. If you're getting to know your home airport, get started by taking the interactive tour of a typical general aviation community airport on the AOPA Flight Training Web site.
Not all information is available at a glance. What kind of fuel does your airport offer? When is it available? Are there runway lights? What type and intensity? Knowing the layout of your home airport and those you visit is responsible piloting, and it is fodder for questions on your private pilot practical and knowledge tests. Knowing how to research an airport's infrastructure and interpret what you find out is also on the tests.
Sometimes you may have to do some digging. For instance, VFR aeronautical charts give an airport's common traffic advisory frequency (CTAF). But is that the correct frequency for activating pilot-controlled lighting? This topic was discussed in the June 20, 2003, "Training Tip."
The answer: Usually, but not always. Chapter 2 of the Aeronautical Information Manual reviews airport lighting systems and explains: "Although the CTAF is used to activate the lights at many airports, other frequencies may also be used. The appropriate frequency for activating the lights on the airport is provided in the Airport/Facility Directory and the standard instrument approach procedures publications. It is not identified on the sectional charts."
The airport rotating beacon is another important airport fixture. And you may have learned that daylight operation of a rotating beacon often proclaims weather conditions below basic VFR. But again, not always. Says the AIM: "At many airports the airport beacon is turned on by a photoelectric cell or time clocks and ATC personnel cannot control them. There is no regulatory requirement for daylight operation and it is the pilot's responsibility to comply with proper preflight planning as required by 14 CFR Section 91.103."
Airport infrastructure is the focus of numerous questions on pilot knowledge tests. Check your knowledge by reviewing some sample questions. Once you know the airport layout, always check notices to airmen to verify that components are working before you fly.
