Good to know. EX-RAN A4G, then modified to EX-RNZAF A-4Kahus still fly today with DRAKEN USA. I'd be very happy to keep the thread on the F-35C topic however as you can see - if you read the posts - many others comment about 'other things'. That is the way of pPRUNe. Please DISTRACT ME with your insights into your experience with NavAv. TIA. AS I started this thread and have gleaned a lot of info on the F-35C over the years; I would like to see pilot comments about it for sure. Some here question my NavAv experience; as I question some others. Again 'the way of the pruners'. I'm always glad to get back on topic.
