🔍 Key Concepts

• International Code of Signals (INTERCO) radiotelephony pronunciation of numerals (e.g., Unaone, Bissotwo, Terrathree, etc.) • How decimal points are spoken in ICS radiotelephony groups • Difference between plain English number words ("one, three") and code numeral words ("Unaone, Terrathree")

💭 Think About

• Look at which choices use the special ICS numeral words and which use normal English words. Which form does the International Code of Signals require for groups? • Consider how the decimal point is pronounced in ICS: is it "point" or "decimal" when reading out a code group like 1.3? • Ask yourself: in an ICS group (not just an ordinary number), do you use the special code words for each digit, or the everyday spoken numbers?

✅ Before You Answer

• Verify the official ICS numeral pronunciation table (Unaone, Bissotwo, Terrathree, etc.) and see which digits appear in the group 1.3 • Confirm from ICS whether the **symbol "." in code groups is spoken as "decimal" or "point" • Check that the option you choose uses both the correct special numeral words and the correct word for the decimal sign.
