Living in the world of email makes life easier, but can often be exquisitely frustrating. Each day I receive numerous emails, both from people I know, plus, of course, the unwelcome stuff we all get. Most of these emails are requesting a response from me. The frustrating part is when I respond to them, Im too often met by silence. What happened to the sense of urgency? Did they get my response? Did they hear me?When flying with a friend in his ADS-B Out-equipped Mooney, we began to wonder the same thing, but Im getting ahead of myself.

The loss of SpaceShipTwo during a test flight in November wont shut down Virgin Galactics space-tourism project, according to CEO Richard Branson. Branson also said he still plans to be aboard the first commercial passenger flight. NTSB staffers said their investigation wont be complete for about a year, but in the first few days after the accident, they found that the aircrafts feather mechanism — a rotating tail boom intended to slow the aircraft on descent from high altitudes — was prematurely deployed, and initiated the breakup of the aircraft at about 50,000 feet. Pilot Peter Siebold was injured but survived, and co-pilot Michael Alsbury was killed. A second spaceship is already under construction and is expected to launch in 2015.

I have a question that people have been asking me and I dont know the answer.The G1000 has two GPS receivers: GPS 1 is the default choice and automatically switches to GPS 2 if there is a problem. Or you can manually select GPS 2.My question is: Why can only one be used at a time? For example, one GPS could be the primary navigator with the flight plan and the other could indicate final destination or a waypoint on the side of the track or even an alternate.

Many pilots understand that the NEXRAD image they see on datalink weather doesnt exactly show where the rain is falling at that moment because of the delay in broadcasting the information up to the satellites and down to the weather receiver.

I had the pleasure of lunch several years ago with one of the designers of the Boeing 777 cockpit. She said something that has stuck with me for years: Good design obviates the need for training. Held up to this standard, our efforts for GA glass cockpits are a dismal failure. (Perhaps the 777 cockpit is as well; I dont know.)

I understand there are the regulations and then there are the realities of commercial aviation and the pressures GA pilots face when the weather is not cooperating. Like Mr. Smith, I am a professional and I would never tell anyone to be below minimums, in IMC conditions, relying on a VFR chart to avoid obstacles, all while trying to fly a single-engine profile. Encouraging pilots to accept this risk is irresponsible. The chance youll go single-engine at the moment you rotate into IFR conditions is indeed slim, but I can think of few other times when the consequences of poor decision making could be so dire.

Like many of our clinics, this one started with a readers letter. This particular fellow was a flight instructor who had to go old-school with a Private student in a Diamond DA20 equipped with a Garmin GNS 430 GPS. They were following V86-365 from the Bozeman VOR to the Livingston VOR at night through the mountains. Happily motoring along on GPS, they ran into a snag with the bend in the airway.

As pilots or passengers, we fly to go somewhere. That somewhere isnt on an airport ramp, crammed for hours into a stationary airliner. And its not cooling your heels in the runup area with the engine shut down.

Once upon a time it was considered just fine to polish frost smooth rather than scrape the junk off. Now the FAA has changed its mind. The rule is only binding on Parts 125, 135, or 91 subpart F (fractionals), but nine of the 12 frost-related accidents the FAA identified were with non-fractional Part 91 operations, so all of us might take note. Previous FAA guidance recommended removing all wing frost prior to takeoff, but allowed it to be polished smooth if the aircraft manufacturers recommended procedures were followed. But manufacturers never published standards for polished frost, and the FAA said it has no data to determine how to polish frost to satisfactory smoothness.

There arent many legal absolutes about expired data. But will the boxes keep working as expected?Using Garmin as the benchmark, the navigator will continue to work with obsolete data. Flying GPS approaches with an expired navigator database is a legal no-no, but practically speaking, most boxes will let you do it. We wouldnt make a habit of it, but if that LPV is the approach you really need and youre willing to defend your actions under emergency authority, it can be done. Youll want to carefully check every waypoint on the GPS database against a current chart. You may want to double-check with ATC that you have any NOTAMs or changes for that approach as well.
