5: Turn in, intercept the ILS & touch down

Using the default Flight Simulator scenery, when the NAV2 DME reads around 16.5 turn left with a bank of 20 degrees, again using the A/P Manual turn knob.
Note - If we are using Nick Black's scenery we would be looking for 9.0 on the NAV1 DME instead.

Keep a speed of 160 kt during the turn.  We will need around 82% RPM for this.
Select gear down.

During this turn we need to lose 500ft, descending from 2500ft to 2000ft.
To do this click the 'DATUM ADJUST' knob on the auto pilot until we get a 300 ft/min descent rate.

  Click on the Speed Reference Chart.
This will automatically set the bugs on your air speed indicator for landing.
These bugs show the minimum speed with Approach flaps (35 degrees), minimum speed with Landing flaps (45 degrees) and the Threshold speed (VAT).
VAT is the target speed to be at when you cross the runway threshold.

We are aiming to stop the turn at a heading of 300 degrees.
So as the heading passes 290 degrees, click the Manual Turn knob back to the central position & we will level out at 300 degrees ready to intercept the ILS.
Once we are level, turn off the auto pilot & click the auto pilot toggle switch to close the A/P window.

As we intercept the ILS beam, the ILS indicator will start to move on the Horizontal Situation Indicator.
We are now flying manually, so turn the aircraft so that the ILS beam line is kept central under the aircraft symbol.
The horizontal glide slope line is showing that we are well under the glide slope beam, so we need to keep the altitude at 2000 ft until we intercept the glideslope beam.
Since we are no longer descending, we will need some more power to keep the speed between 150 & 160 kt.  About 83 % RPM.

As we intercept the glide slope beam, the horizontal GS line starts to move down the Horizontal Situation Indicator.
As the line passes the nose of the aircraft symbol, select Approach flaps (35 degrees).
Let the speed bleed off, but up the power slightly (to 84%) so that the speed is kept above the first marker bug on the air speed indicator (at 143 kt).
Keep the two ILS indicator lines central under the aircraft symbol.  To keep the horizontal GS line central, we will need to be descending at around 700 ft/min.
You will need to keep the aircraft trimmed by putting in some nose up trim.

As the altitude reading passes 1500 ft, select Landing flaps (45 degrees), allow the speed to drop, but keep it above the next marker bug on the air speed indicator (134 kt).
You will need some more nose up trim.

When we are happy that we are going to land, lower the power down to around 82% RPM and let the speed drop off to the Threshold speed (VAT).  This is marked by the next bug on the air speed indicator.

Before touchdown, set power to idle & flare by reducing vertical speed to under 300 ft/min.
We are going to perform a touch & go, so keep the nose up, raise flaps two notches to take off setting (20 degrees), adjust trim to around 3.5 and apply take off power of 93 % RPM.
