TAKE-OFF ON RWY 23L
After having received clearance to “Line up and wait”, the last preparations for the take-off need to be made:
• Alert the flight attendants – "Cabin crew prepare for departure"
• Check identical values for HDG-bug and runway direction – should be 232°
• Running “Before Take-off Checklist”
After having received clearance for taking off you switch on the landing lights and by that signals to the tower
that the take-off is imminent. First move the throttles forward to achieve about 70% N
1
and check that both
engines are very close N
1
%. By that you assure that both engines are delivering similar thrust. Only then you
guide the throttles beyond CLB-dent into the TOGA-dent and monitor that the target N
1
% is matched while ITT
temperature limit is not exceeded. Any malfunction leads to immediate take-off abortion by the pilot in
charge.
Background information: Taking off in an aircraft is a relative strict process serving safety of flight and noise
abatement procedures. You may divide into the take-off run up to V
1
, the rotation at V
R
and the initial climb at
minimum V
2
+ 10. All these V-Speeds have been defined during flight preparation as per earlier chapters. See
previous chapter of this tutorial.
Rotation at V
R
shall not exceed 3 degree/second, so that the tail will not touch the ground (tail strike). Pitch
attitude will be set to 15 to 18 ° and the trim may be adjusted to match and the gear will be retracted. By that
an optimal rate of climb with a built-in safety margin in case of engine failure and minimal speed can be
achieved.
At 1’500 ft. above aerodrome level (AAL) engine power is reduced for noise abatement.
At 3’000 ft. above AAL the acceleration towards the maximum allowed speed of 250 kts will be initiated. This is
executed by an aligned process of flaps lift and flaps drag reduction with synchronous reduction of engine
power and climb rate to achieve the desired acceleration. You may control the aircraft manually or let the
autopilot have the controls.
REGULAR TAKE-OFF SEQUENCE (WITHOUT SPEED LIMIT ON DEPARTURE ROUTE) FOR THIS FLIGHT:
1. Positive rate of climb Gear retraction and maintain V
2
+10 as minimum.
2. 400 ft. HDG or NAV to be activated
3. 600 ft. Activate autopilot with active HDG or NAV mode
IAS HOLD mode to be engaged – current speed will be set as target
4. 1’500 ft. Pull back throttles to CLB dent and keep minimum V
2
+ 10
5. 3’000 ft. Target speed set to 210 kts (maximum speed for flaps 8°)
6. > 161 kts Flaps retraction to position 1
7. > 180 kts Flaps retraction to position 0
8. Flaps are 0 Target speed set to 250 kts (maximum speed <FL100)
9. Climb Check “After Take-off Checklist” to be completed
