Dark clouds are looming on the horizon of our otherwise exciting GPS future. With increasing frequency, the military is jamming or spoofing GPS over huge swaths of airspace. A typical GPS NOTAM for Albuquerque center covers a radius of 237 NM at 10,000 feet, 207 NM at 400 feet and 165 NM at 50 feet daily for most of a week. Pilots in the Southwest have become accustomed to these NOTAMs, but theyre becoming more frequent and expanding to other areas of the country.

Likely you either practice approaches to non-towered airports or fly into airfields with part-time control towers. Non-towered airports, hotbeds of GA activities, present our greatest risk of a midair collision; a risk mitigated by a disciplined adherence to procedures (proper entry into landing patterns, proper departure patterns) and proper use of the UNICOM frequency at uncontrolled airports. (FAA Aviation News, May/June 2001) Therefore, its important that instrument pilots play nice around the pattern. The updated AC 90-66 covering non-towered airports specifically identifies instrument pilots, maybe because of some past misbehavior.

An approach to safety of dont have an accident and always effectively weight risks doesnt work because we dont take actions we think will cause accidents. Tom Turner recently presented a Wings seminar, Stop Teaching About Safety, covering this. Safetys an integral outcome, not a separate goal. Instead, he suggested approaching flying as its master and commander: The result will be safety. While being master and commander will work for all pilots, the instrument environment presents unique challenges to achieving that goal.

Jeppesen is updating symbology for STARs and SIDs charts. As part of the change, Jepp contracted with an outside firm to conduct an operational risk analysis. After an in-depth evaluation of the mitigation possibilities TRS recommended to Jeppesen to create a training tutorial.

While I was driving to the airport a layer of radiation fog condensed and became a pattern-smashing iron plate by flight time. While waiting for tower to cut the next ATIS, I poked around weather forecasts and noticed that the MOS forecast predicted, correctly, low ceilings for the rest of the morning. Argh!

In 1957 the Soviet Union launched Sputnik, the first man-made satellite. The American psyche was troubled by the potential of this technological second place. This planted the seeds of one of Americas greatest military and technological innovations-GPS.

Shakespeare elegantly downplays the importance of naming in Romeo and Juliet, writing: Whats in a name? That which we call a rose by any other name would smell as sweet. What matters is the subject and not what the subject is called. But this is an over-simplification because changing the subject would make the quote non-sense: That which we call a fish by any other name would smell as sweet. Words have meaning.

Maybe were too busy focusing on the forest and the trees that the dirt making up the foundation of the arbors is ignored. Or perhaps its the elephant in the room no one discusses. Instructors dont teach it because they dont understand the opaque system themselves-cant teach something you dont know. Whatever the cause, many pilots have a poor understanding of how aeronautical information travels through the system and how charts are updated.

Regulations prevent collisions through right-of-way rules. These codified decencies apply to the road, sea and air. For aviation, 14 CFR 91.113 warns that regardless of whether an operation is conducted under instrument flight rules or visual flight rules, vigilance shall be maintained by each person operating an aircraft so as to see and avoid other aircraft. Sage advice, that, especially with our butts in the hot seat.

The old saying tells us you cant be cleared for takeoff until the gross weight of the paperwork exceeds that of the aircraft. That hasnt changed much since Flight Service received reports on Teletypes necessitating cryptic abbreviations to conserve precious bandwidth on 75-baud lines. Calling Flight Service used to be required to file a flight plan and get a weather review from a specialist with information unavailable anywhere else. Technology has changed all that.
