23 Questionnaire COUNTING AND ESTIMATING AIRCRAFT OPERATIONS AT NON-TOWERED AIRPORTS QUESTIONNAIRE 1. What method of estimating aircraft operations at non-towered airports is used in your state or at your airport? (This is the number of operations used in the airport master record form, system planning, master planning, forecasting, and for other managerial uses.) A) Expand a sample count using seasonal or monthly adjustment factors ____ B) Multiply a predetermined number of operations per based aircraft by the number of aircraft based at the airport ____ C) Statistical model ____ D) Other (please specify below): _______________________________________ 2. If you answered statistical model, please indicate the type of statistical model you employ to estimate aircraft operations. ____________________________________________ 3. If you estimate from a sample count, what method do you use to collect the sample data? A) Acoustical counters ____ B) Pneumatic counters ____ C) Visual counts ____ D) Airport guest logs ____ E) Other (please specify the method below): _____________________________ 4. If you estimate from a sample count, how long does the sample count last at an individual airport over a year? A) Week(s) (specify number of below) ____ B) Month (specify number of below) ____ C) Year ____ D) Other (please specify below): ________________________________ 5. Do you sample traffic at an airport in more than one season? A) Yes (please specify which seasons below) ____________________________ B) No ____ 6. If you use equipment to sample data, what is the approximate cost of the equipment per unit? A) Less than $2,000 ____ B) $2,000 up to but not including $4,000 ____ C) $4,000 up to but not including $8,000 ____ D) More that $8,000 ____ Please specify the name and manufacturer of the equipment. _________________ 7. How many runways will one unit cover?

24 A) Less than 1 runway ____ B) 1 runway ____ C) 2 runways ____ D) 3 or more runways ____ E) Other (please specify below): _____________________________________ 8. What is the accuracy of this method? (100% indicates all operations were accounted for, none were omitted, and none were erroneously included.) A) 80%–100% ____ B) 70%–80% ____ C) 60%–70% ____ D) Less than 60% ____ E) Don’t know ____ 9. Did you answer Question 8 based on your opinion/hunch or did you actually perform some type of accuracy tests (either formal or informal)? A) Hunch/opinion ____ B) Formal or informal accuracy tests ____ 10. Approximately how many person-hours does it take to perform a traffic count at an airport using this method (excluding travel time to the airport)? A) Less than 2 hours ____ B) 2 hours up to but not including 4 hours ____ C) 4 hours up to but not including 6 hours ____ D) 6 hours up to but not including 8 hours ____ E) Other (please specify below): _____________________________________ 11.
