Weather-wary, and wise

Every experienced pilot can tell a story about encountering surprising weather. But the story is only something to learn from if that pilot did a good job studying the weather before and during the flight.

As summer 2011 approaches after a long, snowy winter, followed by a tornado- and flood-filled spring, pilots have been given more than enough reminders of the importance of weather awareness. Fine-tune your prep by paying special attention to clues that rapid change may be afoot during your expected time aloft.

A high dew point that appears in your departure airport’s or destination’s surface aviation weather observation METAR tells you that the atmosphere could become very active.

“High dew points correlate well with the probability and severity of thunderstorms,” Thomas A. Horne explained in the March 2003 AOPA Pilot Wx Watch column. “Once thermals, fronts, and other lifting forces go to work on air masses with high dew points, towering cumulus or cumulonimbus clouds can soon follow.”

He added this important caution: “Most severe thunderstorms (those with 50-plus-knot surface winds, three-quarter-inch hail, or tornadoes) happen in air masses with dew points above 70 degrees F (21 degrees C).”

Even if your last weather briefing still seems fresh, update it just before departure and check the latest radar imagery for any signs of new activity.

Good to go? Have your list of frequencies for your personal early warning network handy. It should include Flight Watch and navaids that broadcast hazardous inflight weather advisories (HIWAS).

The broadcast of a convective sigmet may be your first alert to weather developments. “When first issued, ATC will broadcast convective sigmets over frequencies used in instrument flight rules operations. VORs with HIWAS capability will broadcast convective sigmets. And, of course, flight service will tell you of any convective sigmets via flight watch (122.0 MHz) or one of its designated flight service frequencies,” Horne wrote in the June 2001 Wx Watch.

Under favorable conditions, no adverse weather comes to life more spontaneously, and can develop more quickly, than a thunderstorm or an area of thunderstorms.

Just as you scan your instruments for proper heading, altitude, and airspeed, keep checking your early-warning system on weather conditions ahead, and be ready with alternate plans of action for every point along your route. The Air Safety Institute’s WeatherWise: Thunderstorms & ATC online course can give you additional insights about safe approaches to convective activity.


No person will be more influential in nurturing your desire to fly than your first flight instructor. A good flight instructor will make the flight training process enjoyable while teaching you the intricacies of flight at a pace that is suitable to your schedule and level of learning. Begin your research by reviewing the Flight Training website for helpful articles on selecting an instructor. To find an instructor in your area, go to our searchable database of flight instructors.


Did you know that student pilots who join AOPA are three times more likely to complete their flight training? Membership includes unlimited access to aviation information by phone (800/USA-AOPA, weekdays from 8:30 a.m. to 6 p.m. Eastern time) or from Flight Training Online or AOPA Online.

Community can help improve flight training

Anyone who has ever taken flying lessons can help improve the training process by sharing his or her input in one of a series of regional meetings. The first one kicked off May 24 in Fairfield, N.J., but more sessions are scheduled. Read more >>

TSA letter to CFIs ‘voluntary’

AOPA is working to help certificated flight instructors in the Baltimore, Md., and Washington, D.C., areas determine how to respond to a “voluntary outreach letter” they may have received from the Transportation Security Administration. The letter reminds active flight instructors of their obligation to comply with training requirements outlined in transportation security regulations. Read more >>

New search function on airport directory

Want to enhance your $100 hamburger? Search destinations, events, and attractions near airports on the advanced search page of AOPA Airports, thanks to a new widget powered by OneTankFlights. The widget will persist for about six months as part of a trial arrangement. Read more >>

Challenge yourself with an IFR chart

Part of the joy of flying is the sense of accomplishment that comes with mastering new skills. For many pilots, the next big challenge beyond the initial checkride is an instrument rating. It’s a different world of flying, one that requires a whole set of new skills—like understanding approach charts (small maps that show the procedures used to land in poor weather). If you’ve ever wondered about life on the other side of the instrument flight rules divide, the Air Safety Institute’s IFR Chart Challenge: ILS Approach is worth checking out. Get started >>

Human-powered helicopter lifts off

Students from the University of Maryland successfully test flew a human-powered helicopter on May 12, and its female pilot hovered the aircraft long enough to file for a world aeronautical record. Read more >>

Why is understanding density altitude important?

We know the textbook definition of density altitude: pressure altitude corrected for nonstandard temperature and pressure. But do you know how that translates into your summer afternoon flights? Learn how density altitude affects your aircraft performance and why you should incorporate it into your preflight planning with the latest safety quiz from the Air Safety Institute, sponsored by the AOPA Insurance Agency. Take the quiz >>

News from the medical front

The FAA appears to be centralizing its medication usage policy for medical certification, making it more difficult to obtain timely information on changes to medications, AOPA Director of Medical Certification Gary Crump reports. Read more >>

The AOPA Credit Card rewards you for summer travel

Nothing shakes off the winter doldrums quite like planning a summer vacation. Deciding where to go is the fun part; figuring out how to pay for it not so much. Lucky for AOPA Credit Card holders, their summer vacation can earn them rewards points all along the way. Every purchase made with the card earns one point for every dollar spent, which can be used toward cash, gift cards, and other rewards. Plan on flying to your destination? You can earn two points for every dollar spent on select AOPA products and services and purchases at more than 4,000 participating FBOs. Each time an AOPA Credit Card is used, vital funding is generated to help support AOPA’s expanding campaign to popularize flying and to grow the number of general aviation pilots. Don’t have an AOPA Credit Card? Apply today.


Universal GPS receiver from Sporty’s

You can turn your smartphone or iPad into a GPS with the right application and a universal GPS receiver. This unit, sold by Sporty’s, communicates via Bluetooth with iPad, iPhone, iPod Touch, and many Android, Windows, and Blackberry smartphones and tablets. Use the receiver with ForeFlight, WingX, or other programs. Its rechargeable battery lasts 8.5 hours, and it comes with both a USB cable for charging and a 12-volt car charger. The receiver sells for $99.

Question: What is the difference between best rate-of-climb speed and best angle-of-climb speed?


Answer: Normally after takeoff a pilot is interested in reaching cruise altitude in the shortest possible time. Only one speed will do that: best rate-of-climb speed, or V Y. This airspeed provides the greatest gain in altitude in the least amount of time. There are other instances, such as obstacles, when a pilot wishes to gain as much altitude as possible in the shortest distance. In this case, a pilot would choose the best angle-of-climb speed, or V X, which provides the greatest gain in altitude in a given distance. The different airspeeds that either limit or result in specific aircraft performance are known as "V" speeds—V for velocity. The different V-speed abbreviations are listed in 14 CFR 1.2. For more information on all the V-speeds and their effect on aircraft safety and performance, read about airspeed on AOPA Online.
