I have a little question regarding flight planning in China. I observed an event at VATPRC (Tour of China leg 14) and saw the following air routes:
Suggested Routes
ZUCK-ZLXY
AIRAC:ALDEL W550 GAO W504 VENON G212 NSH
NAIP:SULEP H4 NSH
FL266(8100m)/FL291(8900m)/FL311(9500m)
Does anyone have an idea what NAIP is? Furthermore, the AIRAC route is far from economic with a lot of extra nautical miles. The ‘NAIP’ route suggests a H4 airway, but on skyvector this doesn’t exist…
On Flightradar24, I saw airplanes from Xi’An to Chongqing coming from a northern direction, instead of the way all around in the direction of Chengdu. Are those ‘hidden’ airways? Or can anyone tell me more about this or is NAIP something special in China?
AIRAC uses the data published on CAIP for China. China has another set of AIP called NAIP, this is strictly controlled inside China as it includes many military information and airways. As an international pilot that flies into China, he/she does not need to know these information, simply fly what was given to them.
Thank you very much for the reply! Now I understand why there are so few airways available in China… Unfortunately the NAIP is not published… But since the assigned route at the event (Airway H24) used those ‘secret’ airways, the information should be available to some people. I guess it is not shown on the internet =D… Is it true only Chinese carriers use them and foreign airlines do not ?
