Procedure Turn

Recommended Posts

Hello,

 

while skiping thru the Manual today I found something that caught my attention: Procedure Turns. Especially the symbology on the ND as described on 10.40.19 FCOM 2. Sooo...are they modeled? And if yes at what airport can I find them?

 

Thanks in advance

Frederik

Hi,

 

They're not modelled as far as I'm aware. The MD-11 has the option for pilot-programmed PT but they never implemented it (sadly)

 

I've not seen it in the 777 so far either.

 

Best regards,

Robin.

Try the ILS 27 approach at EHAM/AMS (Amsterdam) that involves a 270 degree teardrop turn but I'm not sure if that is what is defined as a procedure turn.

Not modeled - it would be incredibly rare to be given an approach involving a procedure turn in a 777 in the real world btw. You can always do it in raw data anyway too - a procedure turn is not defined by the FMC/ND, it's defined by the ground navdaid and leg times, similar to a hold.

 

Adding this and a couple other things is going to require a ground-up reworking of our navdata syntax and formatting - it's something that if done is going to add a least a year of development time to the product whose development period it happens in. This is is basically ripping out the core of the FMC and it opens a huge can of worms for potential issues - we're not keen to do it for that reason.
