And to clarify another; the data we are talking about is from the flight data monitoring system. In the most modern systems, this data is transmitted by mobile phone to the collection centre, generally a company not directly connected to the airline but an independent body employed by the airline. They then analyse the data and report any exceedances, deviations etc that fall outside the designated parameters to the moderator within the company.
Flight data recording is stored on the hard memory within the 'black box' in the aircraft. This data will is accessed directly after each flight or when the aircraft transits through a base where engineers have the equipment to retrieve and transmit the data.
Both EZY and RYR have the data transmitted automatically after every landing so walking away after your arrival and hoping the company will not find out about your +30kts at 100' or the two dots low at 800' is a false expectation.
If a particular pilot has more than his fare share of Class 1 incidents and a regular smattering of Class 2 then he will surely be invited for further training, interviews, warning letters and ultimately dismissal.
You cannot escape the long arm of FLIDRAS (or whatever your system is called) and nor should you be able to!
