Final answer:
Wind data for the runway in use can be determined using alternative methods such as weather stations, meteorological forecasts, and real-time updates from other pilots.
Step-by-step explanation:
When wind equipment is inoperative, wind data for the runway in use can be determined by using other methods. One method is to rely on weather stations near the airport to provide wind data for the area. Another method is to use meteorological forecasts to estimate the wind direction and speed.
Pilots can also communicate with air traffic control to get real-time wind updates from other pilots in the area. By combining these different sources of information, pilots can make an informed decision on the wind conditions for the runway in use.
