To fly accurately, pilots need to perform instrument scans before, during, and after maneuvers. This involves interpreting the heading indicator, artificial horizon, and other instruments to make precise adjustments to stay on course. It's important to check both primary and secondary instruments and cross-check data to ensure accuracy. Unit 11. Instrument Scan. Exercise 5, page 25. Wing Tip of the Week. Know your instruments. Any experienced pilot will tell you that you can't fly until you can scan. To stay on course, you must perform accurate instrument scans before, during, and after every maneuver. If you are banking, for example, your heading indicator and artificial horizon tell you your heading and bank angle. As you change course, you must precisely adjust the trim of your rudder and ailerons. If you don't properly interpret your instruments as measurements, these adjustments could be inaccurate. You might bank too much or too little and struggle to stay on course. During a maneuver, one or two factors typically remain constant. Read your primary instruments carefully to ensure these factors don't change during the maneuver. But don't forget to check your secondary instruments, too. These will give you an indication of how your maneuver is progressing. Finally, remember not to rely too much on any one instrument. Cross-check your data with other instruments to make sure you have accurate information.
