How are corrections for altitude data made on a flight progress strip?

1. By using a double line to cross out

2. By writing the correct information above it

3. By using a single line to delete the wrong information

4. By adding a note for the change

The correct answer is: By using a single line to delete the wrong information

Corrections for altitude data on a flight progress strip are made by using a single line to delete the wrong information. This method clearly indicates that the original altitude has been altered without completely obscuring it, allowing for a traceable record of what the previous information was. This approach maintains the integrity and clarity of the data, ensuring that all parties who review the strip can see both the previous and updated information. The use of a single line essentially strikethroughs the incorrect data, making it obvious that a correction has been made, while still allowing the remaining details on the strip to be readable. While crossing out with a double line or simply writing the correct information above could lead to confusion about which pieces of data are current and which are outdated, the single line method strikes a balance between clarity and legibility, thereby making it a standard practice for altitude corrections in air traffic management. Adding a note for the change, while informative, does not visually indicate the specific data that has been altered, which can create ambiguity in busy operational environments.
