You are flying in an area where Controller-Pilot Data Link Communications (CPDLC) are being used and you send the following message:
‘‘REQUEST WEATHER DEVIATION UP TO 15 NM LEFT OF ROUTE’’
Which of these options is the most probable initial CPDLC response from ATC?
Following the request of a weather deviation, let's look at the ATC answer options:
"ROGER" --> INCORRECT. This means only that the information has been received. This is an inadequate response from ATC for a deviation request. ATC will need to either deny, allow or modify the request.
"STANDBY" --> CORRECT. Ultimately ATC will need to either deny, allow or modify the deviation request but could use 'standby' in the meantime as they consider the overall situation.
"WILCO" --> INCORRECT. Wilco is a mash up of 'will' and 'comply' and does not make any sense as a response from ATC.
"AFFIRM" --> INCORRECT. Affirm just means 'yes' and again, does not make any sense as a response from ATC. They would be responding to a deviation request by just saying ‘yes’, whereas ATC need to give proper approval.
