Anybody know what the flashing I and O is in the glideslop ticker tape area? I had a flashing I (flashing black and white) just after takeof where the green G normally is (green G in screenshot as I wasn’t quick enough to capture the flashin ‘I’). I also had a flashing ‘O’ when I was on approach which I aslo have no idea about?
Can anyone help by letting me know what these are for please?
Thanks
