Why would I be a librarian Problemchild? You obviously have little experience in the training and testing of fellow aircrew. While a bad speller may have good hand/eye co-ordination and be able to pole well his lack of pride in his written work is an indication that he may not cope when the chips are down. My old RAF instructor said he could teach anybody to fly but not everybody to operate. My course started with 16 (all with previous Chipmunk flying at UAS) but 8 were chopped for not having that extra capacity required to operate the a/c. In 30yrs of flying both fixed wing and rotary I have witnessed pilots who could fly the a/c perfectly well when things were going well but whose standard of accuracy fell sharply when faced with out of the ordinary conditions, because they became overloaded . So while there may not be a direct link between bad spelling and lack of capacity I would be reluctant to invest in an applicant who sent a badly spelled CV as it shows a lack of pride and also laziness in not using spell checker.
