Factors Affecting Errar Margins
Factors Primory influencing errir margins include:
- 111; FLT: 0: 03; Teart and Wind: FLT: 1 Aver3; SP3; External forces can alter the vessel 's course and speed.
- FLT: 0 = 33. Instrument Accuracy: 1f 1; FLT: 1 1f 3; Eror in conquas, speed log, or GPS devices contribute to inimoraciees.
