(Airbus) In my company we have to call "Flare" at 30', if there is no flare !!!
How confusing is that ??? Completely bonkers. It gives the Captain about 0.0001 second to react, and then he has to process the call, process what it means and process a response.
For a start, as has been pointed out; 'Flare' should appear at 40', so that would give a fraction of a second longer for Cap to react. Secondly, the call should not be "Flare" it should be "Go Around". There is not enough time for a human to process the implications of a "Flare" call, but on hearing "Go Around" the response is automatic and virtually instantaneous.
