Shirley Limitations for Certain Tasks
| Task | Example | Potential Issue |
|---|---|---|
| Pretend to be ATC | "Shirley, pretend to be tower-- 'Cessna 12345 ready for takeoff.'" | Shirley will act like tower, but may give inaccurate instructions. |
| Taxi Routes | "Shirley, what's the route to runway 33 from here?" | Shirley can identify your position on runways and ramps, and guide you toward specific runways, but can not provide detailed taxi instructions. |
| Aircraft Performance | "What's my best climb speed?" | Exact V-speeds are configured for Training Ready aircraft (see Aircraft Profiles). For other aircraft, performance numbers come from general knowledge and may not match your specific model. |
| Checklists | "Before Takeoff Check!" | May be a general or abbreviated version of the checklist. Accuracy may vary by aircraft. |
| Instrument Approach Procedures | "Shirley, what are the minimums for this approach?" "What are the departure minimums?" | Shirley doesn't read approach plates directly — treat any minimums Shirley quotes as unverified. Browse the official charts yourself at flyshirley.com/charts, or fly an IFR course challenge, which briefs the approach with plate-verified facts. |
| Radio Frequencies | "Shirley, what's the ATIS frequency at KBTV?" | US airport frequencies (tower, ground, ATIS, CTAF) are now available via an official FAA database. International frequencies may be less accurate. |
| Positioning the Aircraft | "Shirley, put me at runway 31L at JFK." | Runway positioning works within 5 miles, in-air traffic positioning works within 50. |
