Last but not least is the practice of ducking under--descending below minimum descent altitude (MDA) or decision altitude (DA)--to pop out the bottom of an uneven cloud deck and continue the approach when the runway environment isn't in sight.

Top five IFR mistakes: once you 're behind the airplane, getting back out in front can be a challenge. Good planning and cockpit management skills can save the day

Descend to your minimum descent altitude." From this point on, ATC will simply call your heading as seen on the scope, and your trend.

Trust, but verify

Pilots must not correct altitudes published on Standard Instrument Departures (SIDs), Obstacle Departure Procedures (ODPs) and Standard Terminal Arrivals (STARs) but they must use the corrected Minimum Descent Altitude (MDA) or Decision Altitude/ Decision Height (DA) as the minimum for an approach.

Certification changes: while the FAA's new part 23 goes into effect August 30, the agency's aircraft certification service gets reorganized

MDA Minimum Descent Altitude: The minimum altitude to which you may descend on a nonprecision approach unless you see the runway environment.

The acronym jungle: technology spawns acronyms. Since aviation gets more technology every day, like it or not, acronyms come along for the ride and there are many we simply need to know

This includes minimum descent altitude and decision altitude.

Impaired flying targeted: the FAA wants to increase pilot awareness of impairment by alcohol, drugs and fatigue

Using the practical definitions, nonprecision minimums are expressed in terms of minimum descent altitude, MDA, and precision approaches have decision altitudes, DAs.

Approach secrets: we've never had so many approach choices to get into an airport. Which one to use? We help you sort out all the factors to find your answer

Minimums are a minimum descent altitude (MDA), as with a VOR or localizer-only procedure.

RNAV approach types: what you can fly depends on how you're equipped, but ILS-like minimums based on GPS are common

Obstacle protection depends on the aircraft crossing the missed approach point at or above the minimum descent altitude, so an early climb is fine, but an early turn is a bad idea.

That placid sensation: considering all the advances in aircraft systems, it's amazing how some of the basic ones haven't changed since aviation's early days. Even in glass houses, some tools are stone age

There's long been an argument about how to execute a non-precision approach (NPA) with a minimum descent altitude (MDA): Use a constant-angle descent or the so-called "dive and drive" method--a steeper descent to the MDA and leveling off, then looking for the airport.

Spin off ATC? New legislation would create an air traffic control system independent from the FAA

When the pilot is established on each required segment of the IAP and the IAP is "flown" to the minimum descent altitude (MDA) or decision altitude/decision height (DA/DH);

Logging approaches: recent FAA guidance clarifies when you can log an approach in IMC for practical tests and proficiency

unless the instrument approach procedure must be abandoned for safety reasons, we believe the pilot must follow the instrument approach procedure to minimum descent altitude or decision height."

How to ace an IPC: if winter meant little flying due to frosty clouds, then it's time to review what the hell you're supposed to be doing up there

The minimum descent altitude for the ILS Runway 2, circle to Runway 20, was 720 feet msl.

Tight circle: when circling to land, it's important to remember stalling speed increases with bank angle
