Whilst there is information in the manual that describes how and when to execute a Missed approach it doesn't actually talk you through step by step from a go around to diverting or landing at the same airport.

 

I would like to invite posters to describe in detail how they would execute a published missed approach from both

A. Manual approach

B .using the A/P

C. Interaction with ATC

A. It would be a F/D go-around. FCOM 4.20.27, FCTM 5.85.

B. If you were using single autopilot channel, then it will disconnect and you'll execute F/D go-around.

With both channels active an automatic GA is possible FCOM 4.20.25, 4.20.30.

ATC will give you another approach, you enter it in FMC and fly.

 

C. Do you mean that ATC will vector you? Then this's not a published missed approach.

 

diverting

 

FCOM SP.11.7. This manuals are the best step-by-step guide.

rsvit, what is the expected interaction with ATC? lets say ATC tell you to fly a published missed

You should have the missed altitude already set in the window. I do not know the published procedure but here what I would do is assuming hand flying;

 

1. Hit the Go around button

2. Takeoff power

3. Flaps 15

4. Gear up at positive rate (communicate)

5. Flight Level Change

6. Set speed flaps up MMO

7. Retract flaps on schedule

8. Lateral mode, LNAV or heading select based on missed procedure or instructions

9. AP

 

Maybe a real NG driver can chime in.

rsvit, what is the expected interaction with ATC? lets say ATC tell you to fly a published missed

 

If ATC tells you to fly a published missed approach, read back this instruction and proceed accordingly. No big deal in the real world.

A published missed approach almost always ends in a holding. ATC might assign you an altitude/level different from the charted one if there are other aircraft in the hold already. You enter the hold and stay there until told to do something else or decide to divert to an alternate or you declare an emergency because you're running out of fuel.

To me it sounds like you're confusing two things.

 

1. How to fly the aircraft in the event of a missed approach, which has been covered above and is extensively docuemnted in the manuals.

 

2. What a charted missed approach procedure is and how to exectue it.

 

For 2 there is for almost every instrument approach a missed approach procedure, found on the approach plate.

 

http://www.ead.eurocontrol.int/pamslight/pdf/4e415453/EG/C/EN/Charts/AD/EG_AD_2_EGLL_8-1_en

 

For EGLL 09L ILS (linked above) the procedure can be found in a box to the right of the vertical profile.

 

Climb to 3000 - straight ahead until

passing 1580 or I-AA DME zero

inbound whichever is later, then left

onto track 038°. Continue as directed.

 

In other words, in case of a go around, if you are not instructed otherwise by ATC. Climb to 3000 feet tracking teh runway track, until you pass either the 0 DME on the ILS or 1580 feet MSL, whichever is later(!). So if you go around from 2000 feet you continue until the 0 DME reading (the threshold), if you get the go around in the flare (past 0 DME) you climb straight ahead until 1580 feet.

 

Then you turn left onto track(!) 038, not heading 038 but track 038 (so you have to correct for wind). Then continue on that track until ATC tells you otherwise.

 

The above is a fairly simple procedure, many airports have more complex ones, however often ATC will break you out of those before you end up in a hold or fly them for very long.

This video uses the Wilco Airbus, but it's a nice demonstration of missed approach procedures:

As RSVIT suggested - FCTM tells all regarding the HOW. Do it by the book.

 

Interaction - if you're talking with ATC, they'll tell you what to do. Usually they simply issue a heading and an altitude. The might simply say fly the published missed. If you're not talking to ATC, then when you go missed, you'll fly the published miss and talk to ATC when you can.

 

From that point, it's a matter of telling them you want another approach, a hold, or if you'd like to divert.

Okay I can now refocus on the FCTM with a better understanding of what to expect, and a top notch video that one , the guy really explains the approach and missed very well.

 

Lastly when flying Vatism, what instructions are they likely to issue ? by that I mean are they likely to vector or are we expected to be able to fly a published missed

Same as real world, you're expected to be able to fly a published missed approach, if required ATC will vector you.

 

But yes you should definitly know how to fly it, also don't be afraid to ask for one. Might not be the best if you're flying into EGLl being covered top down by area during a busy evening, but if you want to try one send a PM to ATC and ask if they're fine with it, 95% of time we will be fine with it since it's good practice for us too.

You can expect both published and vectors.

 

If you receive vectors and when it's possible, nice ATC will let you fly runway heading, give an altitude and ask you to contact them for further instructions when the workload in your cockpit has dropped a bit.
