NLT stands for

• A. No More Than
• B. No Less Than
• C. Not Less Than
• D. Not More Than

Answer: (B)

NLT signals a lower bound for a value. It means the quantity cannot be smaller than the stated amount; you must meet or exceed it. The expansion is "No Less Than." In practice, if a rule says NLT 5 knots, you must be moving at least 5 knots. This sets a minimum requirement for safety or performance. This is different from an upper bound, which would be expressed as Not More Than, limiting you to at most a certain value. Some texts use the phrase Not Less Than to convey the same minimum bound, but here the form given is No Less Than, which communicates the same idea: the value cannot be less than the specified amount.
