Falcon 2000LX certified

Dassault Falcon announced the FAA certification of its Falcon 2000LX, a longer-wingspan version of its popular Falcon 2000EX long-range business jet. Read more >>

Emivest restructures, ramps up pilot training

Emivest Aerospace, formerly known as Sino Swearingen, has restructured the company with layoffs at its Martinsburg, W.Va., plant as it matches personnel to current production levels. The SJ30 is a six-seat business jet powered by two Williams FJ44-2A engines and capable of Mach .83 (486 knots) at 49,000 feet with a range of 2,500 nm. It will be built at Martinsburg and San Antonio, Texas. Read more >>

TRAINING TIPs

Minimum float’

There you are, flying final approach after a well-executed traffic pattern, relishing a chance to practice in smooth, calm air. So it’s a bit of a surprise when you level off above the runway and float beyond your intended touchdown point. You make a nice landing when the wheels chirp onto the surface, but you are perplexed that this nice landing had  such a flaw. You must correct it before you demonstrate landings on your checkride. For example, the short-field landing task in the Private Pilot Practical Test Standards requires touchdown “at or within 200 feet (60 meters) beyond a specified point, with no side drift, minimum float and with the airplane's longitudinal axis aligned with and over the runway center/landing path.” Another task, the forward slip to a landing, also stresses minimum float.

 

A familiar dilemma? Think of it as a rite of passage in flight training. “I can land in crosswind conditions but seem to float down the runway in calm weather. My instructor has to take over every time. Any suggestions would be appreciated,” wrote a student pilot in the March 2000 AOPA Flight Training “Since You Asked” column.

 

Here’s a two-step remedy: First, try to visualize what happens when a landing aircraft flying a little too fast encounters the reduced drag of ground effect. “On landing, ground effect can exact penalties for excess airspeed because the same drag reduction may create or prolong ‘floating’ caused by an excessively fast approach,” explains the Jan. 31, 2003, “Training Tip: Ground effect: Playing the float."

 

Combine that insight with a sharpened focus on your own airspeed management. Here’s what flight instructor and aviation humorist Rod Machado specifically advised in response to the student pilot’s question: “Unless the airplane's manual suggests otherwise, try a final approach speed of 1.3 V SO—that's 30 percent above the stall speed for the flap configuration used. Now the airplane is operating close to the bottom of its drag curve. Increasing the angle of attack for the roundout and flare results in an increase in induced drag, which minimizes your chance of floating.”

 

With a little practice, this solution will produce the minimum-float result you want.

Follow 'The Finer Points' on Twitter

The Finer Points flight instruction video and podcast series, hosted by certificated flight instructor Jason Miller, has expanded to Twitter. Just how much flight training wisdom can be dispensed in 140 characters? Plenty, it seems. Here are a couple excerpts: “When landing in a crosswind you sideslip the airplane. This exposes the fuselage to the relative wind and increases drag. Watch your speed.” And, “Using the autopilot can be an AWESOME tool for learning, making it much easier to understand complex operations under IFR in the airplane.”

FINAL EXAM

Question: What is the difference between Part 61 and 141 flight schools?

 

Answer: Part 61 and Part 141 refer to the parts of the federal aviation regulations (FARs) under which the two different types of flight schools operate. The most common distinction between them is the minimum flight time required for the private pilot certificate—40 hours under Part 61 versus 35 hours under Part 141. However, the national average time for earning a private pilot certificate is 60 hours to 75 hours, so this difference isn’t really significant for initial pilot training. It does make a difference for commercial pilot applicants: Part 61 requires 250 hours, whereas Part 141 requires 190. The predominant differences between the two are structure and accountability. Part 141 schools are periodically audited by the FAA and must have detailed, FAA-approved course outlines and meet student pilot performance rates. Part 61 schools don’t have the same paperwork and accountability requirements. Read more about flight schools online, and use these resources for choosing a flight school and a flight instructor.
