Aircraft Type Question

Sat May 08, 2010 10:13 am

Hi guys,

I was wondering about the difference of the aircraft types on flightaware. It either says eg. 77W/Q or 77W/W. They are both 777-300s right? But where is the difference between Q and W?

Thanks for your help
Julian

Thanks.

But why would one aircraft have Reduced Vertical Separation Minimum and an other one wouldn´t?

/Q and /W both indicate RVSM capable according to the list.

Another thread with same question:

The /Q is RNP capable with RVSM and the /W is not RNP capable with RVSM.

RVSM requires special paperwork and maintenance procedures. Two physically identical aircraft may have different RVSM status (and may flip back and forth over time).

Ahh ok thanks.

But why would an airline for example AC order 2 different types of aircraft.

Do they need one special type for a mission?
On the YYZ-FRA route, AC872/873, both types get used.


Sorry for not understanding

You don't need RNP for everything; lots of aircraft don't have some of the higher levels. There are additional costs and training involved.

That's an indication that that route doesn't need whatever level of RNP they're talking about, so either aircraft can do it.
