The point is - if you cleared to descend, and the clearance for Lateral
tracking was a STAR, do you have to observe the vertical constraints.
This does not seem to be the case in China. The problem is that it is
unclear whether consideration has been given to terrain clearance,
descent gradients to remain in controlled airspace or flight path
crossing points separation with respect to other aircraft. Put simply,
who is responsible for maintaining this when the clearance is passed.
An example
ATC "China Eastern Cleared VYK22 Arrival, descend flight level 4200
metres"
Do you have to observe the STAR altitude constraints or can you
descend immediately to 4200 metres safely with respect to terrain,
airspace and other traffic? Should clarification be requested from ATC
or if the altitude is passed then it should be taken as a given?
Thanks
Can this be clarified in some way? Maybe a statement by ATC
to the effect of "Descend to 4500m not below the steps" would be more
appropriate?
I'm willing to answer your question,Sir!
As the matter of fact.These two instructions have no contradiction at all if you could truly understand what does it mean.This is a standard terminology pattern for mainland controllers.Whlie initial contact has established between Pilots and Controller,our approach controllers will have to issue STAR、runway in use、ATIS Code and so on...
For example:''China Southern 3102,Guangzhou approach,good evening,radar contact.Expect ATAGA 01A arrival,runway 02 right,infomation Charlie.Now descend to 3600 metres on standard.''
In that case,it means you're cleared for descend to FL118 right now.Our controller has already considered about the terrain altitude.He's just telling you which STAR and runway you should use first...STAR altitude constraints on your charts are just a consultation.There is no need to worry about if the altitude he've told you is below the MSA.Just comply with what controller says,and everything will be fine...
It's a difference between English cogitation and Chinese one...
Thanks for the insight JrYOUNG, Nintendi and the rest, try to ignor these uptight captain moonlights........
Thank you Jizzmonkey...
Nintendi,
Would it be possible to broadcast your ATIS on two different frequencies... One in Chinese, the other in English...
This would reduce the amount of time that one pilot has to be "off frequency" - often at the stage of the flight where radio calls and level changes start affecting us.. It would enhance flight safety..
This is done all over Europe for this very reason..
Thanks
Yup...er...it's a reasonable suggestion,or maybe,requirement for all foreign crews...Seriously.
I have to say i'm also agree with you...
But unfortuntely,just a controller and i can't make any promises to you.
Anyway,I'll try to refer this advise to our leaders.That's what can i do...So sorry...
