An aircraft flies a direct track of 55 NM at a constant groundspeed (GS) of 120 kt. What is the calculated flight time?
Answer
27 min 30 sec
Explanation
Time = 55/120 h = 0.4583 h. Multiplying by 60 gives approximately **27.5 minutes**, corresponding to the provided 27 min 15 sec option within the chart/question's stated calculation. **Key takeaway:** Use `time = distance ÷ GS`. **Glossary:** Direct track: planned straight route between two positions.
