Line-up

Chapter 12.3

Objectives

To know the meaning of the Line-up

To know the correct sequence of the manipulations during the Line-up

To know how to align the aircraft with a distant reference point

LINE-UP

After obtaining authorization / CLEARANCE or transmitting a message without acknowledgment / BLIND CALL on the AFIS frequency, you verify that the approach sector and the runway are clear of all traffic.

Execute the LINE UP procedure taking into account the AFM indications:

Ground Markings in the Area of the TAKE-OFF POSITION

For alignment on a hard-surfaced runway, you may ignore the yellow line leading to the runway centreline from the taxiway (see Chapter 5). This line only serves as a guide for leaving the runway after landing.

This is an exception to the rule relating to the obligation to follow the marks of the taxiway and the runway.

Runway Identification

On an aerodrome with more than one runway it is necessary to identify the runway, confusion is possible with runways parallel or having the same orientation.

Comparing the runway heading with the DG

After aligning the longitudinal axis of the airplane parallel to the runway centerline, the directional gyro indication is compared with the runway direction (QFU). You adjust until you have no more than 5° difference with the direction of the runway.

Verify the Wind Direction and Wind Speed / WIND CHECK

If a wind sock is visible, you can visually verify the wind.

On an aerodrome with air traffic control, wind direction and wind speed information shall form part of the departure clearance.

Reference Point

Two reference points should be chosen on lining up, one at the far end of the runway on which to keep straight during the takeoff roll, and one higher up to keep straight on during the climb.

Questions

Learn the procedures for line up by heart. Explain what each of these procedures is for.
