When you watch the video on youtube.com, I recommend that you have the video and the text side by side on your screen.
You see Lufthansa (LH) 454 approaching SFO (San Francisco). The aircraft is the biggest passenger airliner in the world, the Airbus A380.
Enjoy watching the calm and professional atmosphere in the cockpit and between the pilots and ATC. You will also hear communication between ATC and aircraft other than LH 454.
Please also note that all instructions are read back to avoid misunderstandings.
The video begins during descent from 11,000 ft:
At 1:08: The captain briefs the passengers on what they can see below.
At 1:22: ATC request the pilots to reduce the speed to 230 kts (426kph/265mph/) (Double the speed of 230 kts and deduct 10 % from this figure and you get a good idea of the speed in kph in round figures (2 x 230 = 460 – 10 % = about 410kph). The first officer ─ in the right-hand seat ─ reads the instruction back.
At 1:35: The pilots are asked to reduce the speed again, now to 210 kts (389 kph/242mph) and to descend to 6,000 ft (about 1,800 m) and, when this altitude has been reached, they shall maintain this altitude until further notice. Observe the read-back again.
At 1:43: The pilots are instructed to contact another ATC unit, namely Nor Cal Approach on the frequency 135.65. The first officer reads this instruction back.
At 1:58: You see the speed 210 kts (389 kph/242mph) in the left side of the instrument, a bit to the right the heading 140, and more to the right the altitude at 6,000 ft (about 1,800 m).
At 2:05: You see that the flaps are extended to flaps position 1, and you see the position on the flap indicator in the cockpit.
At 2:17: You hear the instruction “turn left heading 100.” To avoid mistakes ATC instructs the pilots to a) turn left and then b) fly heading 100. ATC could wish to turn the aircraft to heading 100 by performing a right turn. This will take more time and it could for instance be relevant to increase distance to other aircraft ahead.
At 3:58: The pilots receive the clearance/permission to begin the approach for ILS runway 28R (R stands for the right-hand runway). The pilots are not allowed to begin the approach until ATC gives this clearance/permission. However, the pilots have not yet received clearance to land.
At 5:51: The captain asks for gear down and the first officer extends the gear.
At 6:24: If the pilots must perform a missed approach/go-around they will climb directly to 3,000 ft (900 m) in this case, configure the aircraft for a new approach, or divert to another airport, depending on the reason for the go-around. The 3,000 ft is now set in the instrument, and the pilots do not have to deal with this later in case of a go-around.
At 6:45: The pilots go through the landing checklist. The pilots are asked to change frequency from Approach in SFO to Tower in SFO as the aircraft is getting closer to landing. The pilots get the latest weather for the runway in use and receive the clearance for landing.
At 7:28: The pilots are informed by an automatic call-out that they have descended to 1,000 ft (about 300 m). The pilots check the altimeter in the cockpit and confirm that it is also showing 1,000 ft.
At 7:33: Speed is now 142 kts (263kph/163mph), altitude 800 ft (245 m), heading 285 degrees, ground speed GS (speed over the ground) 134 kts (248kph/154mph). As the airspeed is higher than the ground speed there is some headwind.
At 8:25: Minimum or decision altitude has been reached. If runway is not in sight due to weather or there are obstacles on the runway, a go-around is performed. In this video the captain says “continue” and the landing will be carried out.
At 9:01: Note that the spoilers/airbrakes are activated on top of the wings to reduce the speed after the landing.
The fire brigade sprays water over the aircraft as a tribute to Captain Jürgen Raps, who flew his last flight after 41 years as pilot.
