Essentially none, in fact. But since we recently confused ourselves a lot over all things ACARS related, here is a refresher summary of what it says&#8230;<\/p>\n<h4>Have a read of the intro first<\/h4>\n<p>Point 2.2 of the introduction says this:<\/p>\n<p><strong><i>&#8220;The ACARS Data link\u00a0oceanic\u00a0clearance service is provided by means of VHF and satellite to ACARS equipped aircraft via\u00a0communications service providers ARINC and SITA.\u00a0<\/i><i>It should not be\u00a0confused\u00a0<\/i><i>with FANS 1\/A CPDLC.&#8221;<\/i><\/strong><\/p>\n<p>(I totally confused these earlier, despite having used both.)<\/p>\n<p><strong><i>&#8220;Operators intending to\u00a0participate in the ACARS data link process are\u00a0required to contact their communications service provider and indicate\u00a0they would like to receive the service.&#8221;<\/i><\/strong><\/p>\n<p>So that means the likes of ARINC and SITA.<\/p>\n<h4>The Procedures (in short)<\/h4>\n<p>1. Put the<strong> ACARS logon<\/strong> in, along with your flight number and the OCA facility.<\/p>\n<p>2. Make sure you request your clearance at the <strong>right time<\/strong> (not too early, not too late). Here is the current table of timings:<\/p>\n<div id=\"attachment_18810\" style=\"width: 891px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-18810\" class=\"wp-image-18810 size-full\" src=\"https:\/\/ops.group\/blog\/wp-content\/uploads\/2022\/06\/IMG_13FD676F1141-1.jpeg\" alt=\"\" width=\"881\" height=\"251\" srcset=\"https:\/\/ops.group\/blog\/wp-content\/uploads\/2022\/06\/IMG_13FD676F1141-1.jpeg 881w, https:\/\/ops.group\/blog\/wp-content\/uploads\/2022\/06\/IMG_13FD676F1141-1-300x85.jpeg 300w, https:\/\/ops.group\/blog\/wp-content\/uploads\/2022\/06\/IMG_13FD676F1141-1-768x219.jpeg 768w\" sizes=\"auto, (max-width: 881px) 100vw, 881px\" \/><p id=\"caption-attachment-18810\" class=\"wp-caption-text\">Not too soon, not too late, or rule of thumb&#8230;<\/p><\/div>\n<p>(This is the only change we spotted from the old one &#8211; Gander used to say 90-30 minutes, now it says<strong> 90-60 minutes.<\/strong>)<\/p>\n<p>3.

Once you get your clearance, <strong>check it well.<\/strong> That means checking the LATs and LONGs in your FMC. If the clearance doesn&#8217;t match your flight plan, then both pilots should independently confirm the coordinates and points. If you don&#8217;t like your clearance then negotiate by voice, otherwise send your CLA (clearance acknowledgement). If you don&#8217;t have that function, do it with your mouth.<\/p>\n<h4><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-18818 size-full\" src=\"https:\/\/ops.group\/blog\/wp-content\/uploads\/2022\/06\/Screenshot-2022-06-16-at-13.26.16.png\" alt=\"\" width=\"742\" height=\"312\" srcset=\"https:\/\/ops.group\/blog\/wp-content\/uploads\/2022\/06\/Screenshot-2022-06-16-at-13.26.16.png 742w, https:\/\/ops.group\/blog\/wp-content\/uploads\/2022\/06\/Screenshot-2022-06-16-at-13.26.16-300x126.png 300w\" sizes=\"auto, (max-width: 742px) 100vw, 742px\" \/><\/h4>\n<h4>Some peculiarities with each of the OCAs<\/h4>\n<p><strong>Gander <\/strong><\/p>\n<ul>\n<li>If you&#8217;re departing somewhere <strong>less than 45 minutes<\/strong> from your Gander OEP, then get your clearance 10 minutes before you depart.<\/li>\n<li>Sometimes you might get an ACARS oceanic clearance before you&#8217;ve even sent the RCL.<\/li>\n<li>If you fly an aircraft that is<strong> not able to send an RCL<\/strong>, then you can set yourself up for Gander&#8217;s special service but need to do it in advance:\n<ul>\n<li>Get in touch with your comms service provider and NavCanada<\/li>\n<li>Put AGCS in item 18 of your flight plan<\/li>\n<li>Expect to receive your clearance automatically once you logon<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>Shanwick<\/strong><\/p>\n<ul>\n<li><strong>You<\/strong><strong> must not enter Shanwick without a clearance.<\/strong><\/li>\n<li>If you&#8217;re flying between and <strong>Irish and a Scottish airport<\/strong>, its not very far, so might want to get your clearance before departure.<\/li>\n<li>You get <strong>2 chances<\/strong> with Shanwick.
