Weekend Warrior...by not reporting incidents you have already "done something wrong"...pilots (and controllers for that matter) have no discretion as to whether they file an incident report or not - it is mandatory! In fact the rules state that if you even suspect an incident has taken place you are obliged to complete the paperwork. By not filing incidents you are ensuring that the cause (whether your fault or not) may never be known and yet another opportunity to avoid it re-occurring (with you or someone else) has been missed.
Safety is not the sole responsibility of CAA, it is yours AND mine as well.
