bmibaby & Cork

Ryan, I think you will find Cork Cat II RW17 is a problem for baby for a number of reasons. Operationally, baby treat a Cat II the same as a Cat III and autoland but to Cat II minima. They have found the 73 Classic doesn't like the combination of the undulating terrain in the undershoot of 17 and then the initial slope of the runway resulting in the aircraft landing half way down the runway.

They trialled disconnecting the autopilot at DH but as it's already trimmed significantly nose up [dual channel] the results in the sim weren't pretty.

From recollection there is an additional limitation [AFM] on UK registered Classics that prevents descent below 200ft AAL without visual reference combined with an unltimate min disconnect height of 140ft so a single channel approach wasn't going to work either [below 200ft] IFR.

All in all the airline chose not to pursue different SOPs for one runway in it's route network [as the alternative was considered unsafe] and has to accept the commercial disadvantage to other operators with different types or working to diifferent regulations in this one case.

As for the majority of its destinations it's quite happily a Cat III operator [50ft/200m] in BHX/EMA/MAN/GLA/EDI/BFS[25]/CDG/AMS etc etc.

Hope that explains?
