LANDING GEAR

HUD REFLECTOR GLASS

Visual approach

Flight should be planned with at least a 10% remaining on touchdown. A normal landing pattern uses about 8% fuel.

Reduce airspeed

550 km/h during approach.

LANDING GEAR

DOWN

Check landing gear indicator (3 green fields)

Landing light

ON (LANDNING)

Preselect thrust reversal

if desired.

Set HUD reflector

lower setting (landing mode)

Set master mode

LANDN PAR/ OPT

Do not fly below an airspeed corresponding to 12° α (AoA).

Turn final during descent with a minimum airspeed of 12° α (AoA)

Check indicated airspeed at 1 G that a reasonable value for current weight.

Aim for a 3° angle of descent and reduce airspeed to correspond to 12° α (AoA). The line in the HUD during LANDN P/O corresponds to 2.86°.

Place the descent line on the runway threshold and centre the sight dot on the centreline, steer the flight path indicator onto the line. Maintain attitude. Strive for a touchdown at about 100-200 metres in on the runway

At 15 metres altitude above the runway (30 if not using the radar altimeter), the HUD will change to the descent rate mode. The previous 2.86° line represents the maximum vertical velocity (2.96 m/s).

Thrust reversal (if preselected) will activate once nose wheel is depressed.

to use thrust reversal go full throttle

TILS landing

Set landing base as destination

Press L MÅL

Set QFE pressure on altimeter

Select runway heading

cycle runway heading, BANA/ UT (OUT) and press LS

Set master mode LANDN NAV about 30 km away from the destination

Set Autothrottle ON if desired. Autopilot mode SPAK ON.

Follow steering commands on the HUD or ADI

If using TILS to land, check that TILS is locked (TILS light lit) and used after the LB turn is complete. If using a short approach set master mode to LANDN P/O and then return the master mode selector to LANDN NAV in order to select the touchdown point LF as destination.

Check backup artificial horizon

TILS landing

Lower the landing gear about 15 km out from the runway

Set HUD reflector glass to landing mode about 14 km out.

. Check that the TILS is locked (TILS light solid)

Follow steering commands on HUD or ADI. Maintain altitude and airspeed. The glideslope should be intercepted about 10 km from the runway.

On the descent command follow the glide path steering commands in the HUD and ADI.

If desired set AFK mode 3 (α 15.5)

On touchdown follow normal landing procedures.

Alternate Runway heading selection.

Data selector in mode AKT POS / OUT.

Confirm landing base on the destination indicator.

Data selector in mode BANA/GRÄNS.

Runway heading is displayed on the data indicator.

Cycle runway headings by pressing once or multiple times until the desired runway heading is displayed.

Select AKT POS / OUT.

Flip-flop (shorten approach length)

. Master mode NAV or LANDN NAV (or P/O)

Confirm selected landing base

Select master mode P/O, and then select LANDN NAV

LF should be displayed on the destination indicator.

There are two main styles of braking during landing.

Aerobraking

After touchdown gently pull back the stick to AoA (α) 16°.

Lower the nose at around 160 km/h.

Steer with the rudder.

Apply brakes evenly.

If needed, engage thrust reversal.

Normal braking (with or without thrust reversal)

Lower nose immediately after touch-down

Engage thrust reversal if needed.

Apply wheel brakes evenly.

Steer with the rudder.
