The pilots had completed the taxi and ready for the aircraft take off.
Even before the departure clearance was obtained from ATC, all the required figures had been calculated and set. In older aircraft, we use to write them down in a preset paper and stick it to the panel. On newer aircrafts, there are provision to set them on the instruments or on the aircraft computer.
Some the required figures and data are:
- stab trim (horizontal STABilizer Trim setting – this depends on the weight and balance of the aircraft.
- flap setting – flap is the extension of the wing, to increase the wing area and change the shape of the wing.
V1 – the decision speed. – changes depending on the weight of the aircraft and external environment, temperature and altitude.
VR – The rotation speed, the pilot will pull the joy stick to take off the aircraft.
V2 – the safe take off climb speed.
Engine power setting – the takeoff power.
The Aircraft Take Off
When the aircraft is lined up for take off and the take off clearance is obtained from ATC ..” malaysia 01 clear for take off runway 33″ . The captain will push the 4 trottles forward to the right power setting, his feet will steer the aeroplane, the left hand on the side stick, set it centered.
The FO will counter check the power setting .. “take off power set 102%” . The captain’s R/H will remain on the throttles, ready to abort the takeoff. As the aircraft accelerate, the FO, will monitor the instrument and at 80 knots, he will announce “80 knots check” the captain will glance at his instrument to confirm ” 80 knot check”.
When the aircraft reach the decision speed, V1, the captain removes his hand from the throttles… he cannot abort the aircraft now. at V1, the FO will announce ‘V1′, the captain will remain looking at the runway, at VR, the FO announce, “rotate”, the captain will pull the side stick slowly at the required angle. Too fast a rotation, the tail will scrap the runway, and the pilot be deal with.
The aircraft will slowly climb and the captain will aim at the speed of V2+10 knots, depending on the situation, this can be 156 knots. On positive climb, the captain will order for gear up, the fo will select the gear lever up and wait for the green light to indicate all gear up..”gear up”. At about 100 feet, the autopilot is switched on and the aircraft will climb floowing the standard instrument departure SID.

The aircraft take off is the most critical phase as the aircraft is at its full thrust and at its maximum weight. A small fault can be fatal
