Flight Cancellation compensation
More confused nonsense from Jet2 attached.
Their previous correspondence had blamed the delay on a fault with the No.1 VHF control panel - this particular piece of equipment turns out to be secondhand ('overhauled' as the letter states, whatever that means).
They also quoted previously that this equipment would have been replaced after 48,000 hours use (so called 'soft life'), but it failed after only 2,880 flight hours - the actual 'soft life' for this equipment has reduced to 3,300 hours, which is quite a drop (a clerical error!).
I was slightly wrong when reading this the first time - turns out the 3,300 flight hours referred to is actually what they call 'Mean Time Between Failure' (or MTBF) - however, because Jet2 operate (apparently) something called a proactive reliability programme, the 'soft life' for this particular piece of kit would be around 2,500 flight hours - I interpret this as meaning that it failed 380 hours after it would normally have been replaced under this programme (Jet2 will no doubt put me right on this, as they have with everything else!).
The other confusing element concerns times - our flight was due to depart at 7.30am, but in fact didn't leave until around 10.40am, hence the eventual arrival at 2.02pm (3 hours 12 minutes after the scheduled arrival time). I'm not clear why it took from 8.30am (when Jet2 declared the faulty part in question 'serviceable') until 10.40am to get us all on board and ultimately take-off. I'll have to ask the question I suppose.
Again, reading this for a second time, it looks like Jet2 (and other airlines) use something called Co-ordinated Universal Time (or UTC) - this is effectively the same as GMT, so in my particular case, because our flight was in August (BST), when they quote UTC, I have had to add an hour on to get it match up with the actual boarding/departure times - another thing they try to use to confuse ordinary folk like me.
