How to enter theese kind of waypoints?

Recommended Posts

I found these waypoints in a flightplan out of EKCH - Kastrup, but I don't know exactly what they mean and how to enter them into the route ? Hope someone can help! :)

 

 

- N0450F340

- N0450F220

You don't have to enter them. They usually written in this format KIRAX/N0450F340. It means that you will change your FL at this waypoint.

N0450 means your true airspeed will be 450kt (in Russia you can find K0840 - 840 kph).

F340 means your FL at this point.

 

On airbus there is a dedicated MCDU page called STEP ALTS, where you can enter this.

I see that the full reference for N0450F340 is actually:

 

EKERN / N0450F340 Fix via UM852

 

so I was wondering if 450 was the speed and 340 was the flight level. So rsvit confirms that.

 

Will the steps be indicated beside the fixes on the ND?

Actually I've got an question aswell about these kind of waypoints.

 

- 5230N11000W

- 6213N01500W

 

Is there any way to put this in the FMC?

Yes, from memory this should be correct:

 

N5230.0 W11000.0

N6213.0 W01500.0

I just checked myself and don't use the space, so:

 

N5230.0W11000.0

N6213.0W01500.0

No, it won't.

 

Also, it's just to inform ATC that you put it in the flight plan. You still have to request FL change when you actually want to change FL from your initial cruise level.

- N0450F220

These are not waypoitns. The NO450 is your airspeed in TAS. The FL220 is the altitude you fly at. A real flightplan looks a bit like this:

 

+N0477F330 UA603 TURUT/N0472F350 UA603 GAO UG859 GHA UB726 BSA/N0468F340 UB734 DOLIS/N0471F340 UB734 BALEN/N0468F360 UN854 MRM UM976 BRY UM733 KOPOR UT426 DIMAL UT420 ALESO

 

Lots of NXXXandFXXXs. They are to let you and ATC know when to change altitude for step climbs etc.

They not always step climbs for performance, if you look at the example plan, it's actually a a climb from 330 to 350 which are east bound levels then a descent to 340 a west bound level and finally a performance climb to 360. Sometimes they are included in the flight plans for as direction of flight changes, or certain states have different rules for levels on directions, as in they use north south instead. And finally sometimes they are to get around flow restrictions, you may find a sector as every man and his dog going at f360 at the same time, so a flow restriction will be put on, which would result in a delay to departure, changing the level at this point of the flight will stop the restriction, so putting that into the flight plan, the network computer system picks this up and could mean stopping the restriction.

 

Other times it's quite simply just for performance, as you burn fuel and become lighter you able to climb to a more efficient cruise, but again if this likely this is put in the flights plan so atc are aware for planning and in case results in any flow restrictions.

 

Network management is a very intricate science, and becoming more so, as airlines slowly start to catch up with their operations and understand that better flight planning and keeping up to date with their eobts results in less flow restrictions for them.
