Re: [PSUBS-MAILIST] Re: metric system

Hi David - the altitude in my former aircraft was in metric and in feet
- but if I remeber we use 
in international radio talk allways feet for the high and metric for
distance - to prevent 
missunderstandigs.. was also a test question during our VHF
certification. 

Clear is: 
Houston from Shuttle : "We are down to 30 feet but 3000 meter behind the
airfield"   

Unclear is: 
Shuttle : "We are d..( krcchhh) to 30 meter but 3000 meter (krchhhh,
knack)..ind the airfield"
Houston : "Please repeat - You are 30 meter behind the field ?.." 

And scuba gauge here are in metric - but scuba divers normally never
talk underwater.. 

For Psubs radio talk it is a interessting question.. 

Carsten !-)

Is that just in the US, or this another of those cases where distinct special-interest communities use their own traditional "standards" regardless of the official system of the country they're in?
