10. As the US military primarily flies and trains in US airspace, they use the standard measures associated with the airspace. That is feet (or flight levels), nautical miles and knots, inHg, and °F. Though, using °C is fairly common in the US now since weather reports shifted to the ICAO format. That said, the cockpit systems can be switched ...
Unless Boeing has recently changed to the metric system in their design work, the short answer to the question as to whether Boeing and Airbus use different systems insofar as aircraft manufacture is yes. I'm only familiar with Boeing up through the 747-400. Perhaps others can provide an answer for later models.
14. Europe uses imperial for distance (nm), speed (knots) and altitude (feet). Russia and China are the only major countries that use meters for altitude - and it causes all sorts of confusion. Some aircraft (more in europe) use kilometers and statute miles/hour on the ASI - but the same is true in the US. Share.
Altimeters can be set using hPa (mb) or inHg. In order to calibrate our altimeters for varying atmospheric pressure, we set the current pressure reported by ground stations. Pressure is reported in inches of mercury (inHg), hectopascals (hPa), or millibars (mb). North America and Japan use the inches of mercury measurement.
This in particular occurred after World War Two, and hence mixing them was a bad idea, and the imperial system stuck. Interestingly, the places where the US did not have a lot of influence- the former USSR and China for example- use metric. As for airspeed in Knots and distance in Nautical Miles, this comes from aviation's nautical heritage.
2. All use metric dimensions, only the numbers look sometimes rather odd. This statement is more serious than it might look, in some places you order parts in metric dimensions and they come as 3.175 mm or 12.7 mm. All Russian (and, by extension, all former East Bloc country) engines use metric dimensions. You only see fewer of them.
Use an avoirdupois mass unit, pound-mass (lbm) or long ton, in countries where avoirdupois units are used for business. A320 ECAM, all masses in lbm, source. Use a units of volume, liter (l) or gallon (gal) as suggested in regulations.
Airbus uses metric tools. Hawker uses British Standard Whitworth tools. Dassault Falcon uses (believe it or not) a combination of SAE and metric. Bombardier uses SAE. Share. Improve this answer. edited Mar 25, 2014 at 18:11. answered Mar 22, 2014 at 19:34.
In a nut shell, all measurements are moving to metric so older air craft like the C-130 is all in feet and inches and weights are in kgs. So the trim sheet has to be converted to this. However the newer aircraft like the C-17 and aA-400 are in lbs and meters and again anything loaded has to be converted to the trim sheets.
For me metric or imperial is not the question, from my perspective the key is standardization. Having 2 different unit systems has only got drawbacks: Customers: many airline's customers are living in a metric system, and they do not know what's is a mile or a feet. Is a matter of making flights more comfortable.
