Coded Departure Routes
Pilots want ways to mitigate bad weather. The Coded Departure Route (CDR) is one of the least-known such tools in GA, although its been available since 2007. The AIM tells us, CDRs provide air traffic control a rapid means to reroute departing aircraft when the filed route is constrained by either weather or congestion. So, if youd rather not wait, a CDR might be for you.
What to Brief
The main article covers a lot of things to consider for your various briefings. Here, though, is a view of the items you might want to brief for each phase of your flight.
Weather Planning
Preflight weather planning has long consisted of calling an FAA Flight Service Station. Years ago, you might have even visited one. But, using the Internet, you can now draw on the same resources that meteorologists use. While the 2000s brought weather data to the cockpit, were now getting some Internet tools to the cockpit via dedicated datalink. Although we cant yet cheaply surf the web at cruise, we connect to the Internet at the FBO, on the ramp and in the plane on the ground, using phones and tablets with WiFi and cellular data.
Tips for Weather Planning
Remember that web sites outside the FAA and NWS domains should be considered supplementary tools to be used in combination with a weather briefing through official sources.
More Required Reports
Last months clinic began a detailed look at the reports we are required to give ATC or FSS during an IFR flight. Specifically, we began looking at the reports other than the position reports required by 14 CFR 91.183(a), which well cover separately. The remaining reports come from three sources: 14 CFR 91.183 (paragraphs b and c), 14 CFR 91.187, and AIM 5-3-3.
Online Tools for Icing
When it comes to avoiding structural icing, the enhanced infrared satellite image (
Holes You Should Know About in Official WX Products
Few pilots know that FAA imposes a hard character limit on text products such as Convective SIGMETs and the Area Forecasts (FA). The Aviation Weather Center (AWC) has a check program for the Area Forecast that counts the number of characters. On busy weather days when these forecasters have a lot to mention in the forecast, they often bust the character count. This forces them to cut from either the text or the synopsis in order to make the size fit through the National Airspace Data Interchange Network (NADIN) hubs. Often the first casualty is the ellipsis (...). Forecasters can use two periods instead of three. Another casualty is the synopsis. Of course, the last resort is to cut from the text of the FA.
Bully for the Kids Up Front
I was having fun despite it being a slog on the airlines. Id spun a cancelation of my flight to La Guardia (due to a tropical storm shutting down the East Coast) into a direct flight home from Toronto to Portland. Circumstance even got me into an airport members-only lounge with cozy couches and free food while I got some work done on the laptop.
Blind to the Ice
It was late afternoon and time to fly home after a productive business meeting. Before heading to the airport, the pilot called Flight Service. Most of the significant weather was along a cold front just to the north of his east-west proposed route. The briefer mentioned some light snow showers were showing up on radar near the front. There were a few pilot reports of light to moderate icing, but all of them were associated with the weather to the north. The briefer alerted the pilot to an AIRMET for IFR conditions and mountain obscuration along a portion of his proposed route, but as of yet no en route advisories for structural icing had been issued.
Talk to me, baby
Ive come to believe that single-pilot IFR in a fully loaded, glass-cockpit-but without using an autopilot-can be the toughest IFR flying you can do. The past month has found me in the clouds with and without students in a couple different airframes that I hadnt recently flown. Thats important because I wasnt in the groove with known power settings and trim. Theres more load on the scan when the plane is less familiar and thats where glass shows its biggest weakness: Visual channel overload.
Readback: December 2010
I thoroughly enjoy your IFR magazine and eagerly look for it every month. I do have a concern about the front-page caption, Bitch-slapped by physics, found on the cover of the October 2010 issue. Come on, Jeff. All of you at IFR magazine are excellent writers who know how to get the information out in a comprehensible form and fashion that is entertaining and useful. Using that description for your article about V-speeds is inappropriate.
Hail in Clear Air
Our flight from Potomac Airfield in Friendly, Md.. to Dublin, Va., (to pick up a new puppy) would take about an hour and a quarter, despite steady headwinds paralleling the Blue Ridge mountains. The only minor wrinkle came from two small cells approximately 10 miles north of our destination. The cells were staggered, traveling west to east across our route at 27 knots, with tops at 43,000 feet and 28,000 feet, respectively.
