Common-mistake trap: during the drill, the GNSS display shows a position timestamp 45 minutes old. The student transmits the DSC alert anyway without correction. Critique:
A
Acceptable since DSC is automatic
B
Critical fail — stale GNSS feeds a misleading…
C
Acceptable if within 50 NM of shore
D
Only a minor issue
