| What determines the time used in the METAR report? |

The actual time of a METAR report is the time the last
element of the observation was observed.

What are the designators used on coded aviation weather observations for the following types of

Term
| What time format is used in column 2 of the form? |
|
Definition
A check mark must also be placed in one of the time standard boxes in column 2. The block to be checked depends on the observing
program. An A-PAID is required to check the LST block, while a SAWRS will check the UTC block. Time of the observation in the
transmitted report will always be in UTC (Z).

|
Term
If you discover an error in column 9 after you have given the observation to the tower, you should correct the error by:
a. erasing the erroneous entry and enter the correct data in red,
b. erasing the erroneous entry and enter the correct data in black,
c. drawing a line through the erroneous entry and enter the correct data in red, or
d. drawing a line through the erroneous entry and enter the correct data in black |
|
Definition
Whether the error was discovered before or after the dissemination of the observation, correct
the erroneous data by clearly drawing a single line through the error.
