ATC Initial Tower Block 1 Practice Test

Hazardous inflight weather advisories should be broadcast on frequencies upon which event?

Immediately after the ATIS broadcast Upon receipt of hazardous weather information If it impacts operations within 50 NM of the area of jurisdiction On a priority frequency only

Correct Answer:

Upon receipt of hazardous weather information

Explanation:

Hazardous inflight weather advisories must be broadcast as soon as they are received. These warnings (like SIGMETs, AIRMETs, or Convective SIGMETs) are time‑sensitive and vital for flight safety, so they should be disseminated immediately to all appropriate frequencies and users in the area rather than waiting for a routine update or applying arbitrary distance limitations. ATIS provides routine weather information for pilots on the ground and is not the channel for real-time hazard dissemination. Limiting broadcasts to a fixed radius (for example, within 50 NM) or using only a priority frequency would restrict the reach of the warning and could leave some aircraft unaware of dangerous conditions.
