Let's take a reality check here! No matter how good a Tornado Nav might be at the old EW stuff the front seater on an Apache is a PILOT and a HELICOPTER PILOT to boot! No matter how many spare Tornado Navs are loafing about in crewrooms there are not enough to weather the attrition rate that would be required to put more than a couple of them into the front - PILOTS - seat of an attack helicopter. Now, Harrier pilots - thats another story!
