Even seasoned IFR pilots can find it difficult to quickly and accurately determine the appropriate entry method for an IFR holding clearance. Fortunately, ASA's Holding Pattern Computer helps take the guesswork out of this puzzling requirement. Simply rotate the card's heading indicator to your aircraft's heading and place the heading bug on the assigned holding radial for an instant, at-a-glance suggestion of the appropriate holding entry (direct, parallel, or teardrop). The double-sided card works for both standard and non-standard holds, and makes a fantastic training tool for instrument students. An compact, colorful, intuitive item that should be a part of every IFR pilot's flight bag.
