Just curious about the P-51 FM

The real problem comes with the 'ground hogs', inability to accurately work out what the pilot is saying.

The biggest obstacle is that the 'groundhog' is just not in the pit when the story happens. The pilot has to deal with many variables 'on the fly', and make decisions based on education and experience. For the 'un-educated' these decisions are almost 'natural' and not worth mentioning ??
