General Aviation Aircraft DMMS & VREF Calculation Card, Airspeed Indicator Tape, Placard

Jump on the AQP (Advanced Qualification Program) bandwagon by labeling your Airspeed Indicator (ASI) with your aircraft's DMMS and VREF speeds.

We designed these easy to use cards with your safety in mind. Simply fill the blanks and do the math. Then gently peel off the red and yellow pieces of tape and label your ASI. The remaining plastic credit card sized card, with double sided tape on the back, can then be placed wherever you want. We stuck ours to a blank spot near the ASI.

What's DMMS? Defined Minimum Maneuvering Speed or VDMMS. Dan Gryder has determined that 1.404 x VS1 (stall speed at the bottom of the green arc) is a proven way of avoiding a low-level stall/spin when on climb-out, when in the circuit, when on final approach (until stabilised), when conducting a go-around, or when wanting to achieve best glide speed (in the event of an engine failure in a single-engine aircraft).

What's VREF? It's a calculated reference speed for final approach. Or final approach speed. It's usually 1.3 times VSO or higher. In general aviation aircraft, it's the bottom of the white arc plus 30 percent.

What's AQP? It's a philosophy of flight training adopted by airlines after finding many accidents were due to pilot error. Training is based on specific scenarios a pilot might encounter, rather than teaching maneuvers alone. There's now a big movement to apply this training to the general aviation community. As a student pilot, I fully support this effort. There's a recent upward spike in fatal general aviation accidents, so educate yourself, talk to your instructor, and practice, practice, practice! Don't become a statistic or a "star" in one of Dan Gryder's videos. There's lots of AQP info online. Check out aqpsaves.com. Now get to work!

Note: Tape is removable/reusable blackboard tape and leaves no residue behind when peeled away. It will not damage the glass on your ASI. There's enough tape to label at least two ASIs, maybe three.

Blue skies!
