• check that the INS is automatically switching to the next waypoint
when passing HELEN
• Brussels control has cleared us up
to FL220; our requested cruising
level. Set ALT window to 22000 and
press Alt ACQ, ALT ACQ green will
engage and the aircraft will make a slow 1000fpm climb up to
FL220, keep SPD mode as the active A/T mode.
• when reaching FL220 engage CR mode (if it wasn’t still selected)
on the N1 computer, we are now 10-12 minutes from
takeoff
Cruise
Monitor fuel is being used inside to outside, and fuel use is as
expected.
Check that the cabin pressurisation system is performing as expected
and monitor the progress through the different waypoints. Set the
radios to COA (110.05MHz) and LAM (115.60MHz) as we will be
passing these waypoints later in the flight. Cross check your position
against these waypoints to detect any navigation errors by the INS!
After we passed COA VOR, Brussels clears us direct to SASKI which is
the boundary of the Belgian airspace.
SASKI is waypoint 4 in the INS, to go direct to SASKI from position:
open the CDU’s, on the left (main) CDU: press <WP CHG> (1), press
<0> (2) then <4> (3), press <INSERT> (4)

DESCENT AND APPROACH PREPARATION
Approach Briefing
This is a really short flight and we have no time to waste. So let’s have
a look at what we can expect during the approach into Heathrow.
We expect to land on RWY 27L and the typical STAR from Brussels is
the LAM3A arrival.
Basically the initial approach phase into Heathrow starts at a point
called LOGAN which is located 54.9NM from LAM VOR on the 085
radial. From there we proceed to TRIPO, SABER, BRASO and LAM, all
on the same radial. We have one important altitude restriction at
SABER (30NM from LAM) which we have to pass at FL140. The
minimum altitude over LAM is FL70 and the transition altitude is
6000feet. The QNH at EGLL is 1013 so the transition level is FL70.
To determine our initial top of descent point (TOD) we use a simple
rule-of-thumb:
TOD = altitude loss in 1000 of feet * 3
As we are cruising at FL220 and need to be at SABER at FL140, we will
start descent 8 x 3 = 24NM miles from SABER which is more or less at
LOGAN. Our descent rate will be equal to:
Descent rate = Ground speed * 5
which will be around 1800-2000fpm.
35
There is another important point on the charts called the “SLP” which
is the speed limit point. The SLP is located at 12NM from LAM and we
have to be at 250kts IAS at this point except when advised otherwise
by ATC.
After we pass LAM we switch to a seconds chart describing the initial
approach phase into London.
First we fly outbound LAM on the 275 radial descending to 6000 feet
QNH. At 11NM from LAM we make a left turn to intercept the
outbound radial 129 from BNN (113.75MHz). We can not descend
below 6000 feet until reaching 15NM DME from BNN. After that point
we descend to 3500 feet QNH while reducing speed to 180kts. At
19NM DME BNN we turn right to intercept the ILS for RWY27L after
we cross the 134 radial BNN we can we can further descend to 3000
feet. At 10NM DME from the ILS 27L we can finally descend to 2500
feet until we are established on the glide slope.

Next we switch to the final approach chart.
This chart gives us some more important information. It shows the ILS
course (272°) and frequency (109.50MHz) as well as the decision
height (200 feet AGL) and the minimum safe altitude in a 25NM range
around the airport which is 2300 feet.
We will make a full flap landing, so we will use the automatically
calculated approach speeds and a final approach speed equal to VAPP
+ 5kts.
37
After landing we have to taxi to the main cargo apron, we will vacate
the runway at the high speed exit S6. We will use MED or HI autobrakes
setting in order to vacate the runway as quickly as possible.
That’s it ! Make sure you are familiar with this procedure so you know
what to do when it gets really busy in the cockpit later on in the flight!
Descent Preparation
• check fuel remaining and cross check against the expected fuel
• press the RECALL button on the MWP and check
• obtain landing info at EGLL: winds calm, QNH 1013, expect
RWY27L
• set NAV1 to LAM on 115.60MHz, set NAV2 to BNN on
113.75MHz. Set CRS to 085 as this is the radial we will be
following into LAM
• press the hidden click zone on the ASI to set the speed bugs
