Why Advisory Glideslope +V Can Get You in Trouble

On WAAS-equipped GPS units, many non-precision approaches (like LNAV or LP) will display LNAV+V or LP+V. That “+V” indicates advisory vertical guidance—an internally generated glidepath from the final approach fix (FAF) to the runway. It’s designed to help you fly a continuous descent final approach—a safer, more stabilized alternative to the old “dive and drive” technique. That’s the good news.

Try These New FAA Questions

How well do you really know your instrument flying procedures? Here are 5 of the newest FAA-style questions, recently added to Sporty’s comprehensive online Instrument Rating Course. They’re designed to make you think like an IFR pilot—whether you’re prepping for a rating or just keeping your skills sharp.

The Go/No-Go Decision Isn’t Binary

“Do I fly or not?” It’s a question that may seem simple in the comfort of your living room couch, but in truth, it’s rarely a single, definitive moment. Weather changes. Equipment issues appear. Fatigue creeps in. By the time you reach your destination, you’ve already made dozens of go/no-go decisions. Some of those may have been conscious decisions, but some are instinctive.

Webinar Video: Instrument Approach Decision-Making—IFR Mastery

In this live PilotWorkshops IFR Mastery webinar, the PilotWorkshops team will walk pilots through a realistic, thought-provoking scenario from the IFR Mastery series. You’ll be placed in the cockpit of a Beechcraft Bonanza and faced with a critical decision: how to enter and execute an instrument approach into Wichita Falls, Texas, with low ceilings and strong winds complicating the picture.

Approach Lighting Systems: Scenarios for Instrument Pilots

You’ve probably seen runway approach lights at larger airports many times during your training and when flying at night. These systems take on additional importance when flying IFR since they provide the basic means to transition from instrument to visual flight for landing. If an approach lighting system is available for a runway, the symbology will be displayed in both the small airport diagram in line with the runway, and in the briefing strip towards the top of the instrument approach chart.

Ask an IFR Expert: What actually counts towards IFR currency?

IFR currency seems simple on paper—six approaches every six months—but in real flying, what seems black and white can turn gray in a hurry. Do approaches in mostly visual conditions count? What about simulators, vectors to final, or breaking out early? IFR currency isn’t hard to maintain, but it is easy to misunderstand. The biggest […]

Winter IFR: Practical Strategies for Cold-Weather Flying

Winter brings some of the most challenging — and rewarding — IFR flying of the year. Cold, dense air offers excellent aircraft performance and crisp climb rates, and many days feature crystal-clear ceilings above a thin cloud layer. But the season also introduces hazards that demand a more disciplined approach: icing, contaminated runways, sluggish engines, and unpredictable low-level weather.

Ask the IFR Expert: What do I do when the avionics glitch?

Modern IFR panels are incredibly capable, but they’re still computers—and sometimes they glitch at the worst possible moment. When automation stumbles in IMC or during a high-workload phase, I fall back on a simple sequence: stabilize, simplify, and strategize.
