PilotsEYE.tv – SEA777F – C1 Customer first test flight – Appetizer 5min


We have to make sure… that the alerts
the pilots are trained on… actually work. So we fly at maximum speed. Auto-Thrust off
-Okay. We’ll continue
in a second. Warning lights illuminate?
-Check. Siren sounds?
-Siren sounds, is killed. Overspeed warning displayed?
-Yes. Nose down trim inhibited.
-Okay. Test successful. Then we fly a more than
30 degrees angle. You know what happens. I need to make sure. Then this triangle turns yellow… followed by an aural
warning: “Bank angle”.Then, let me think.
What’s next… Start the APU
(Aux Power Unit)… without air pressure
just electric power… in 39000 ft. The toughest challenge
for this turbine. Bleed Air will be shut off
to bypass the air-starter. turn on the electric starter… she doesn’t like it,
but it’s mandatory. APU selector:
start and release. All the way.
It’s okay… since we’ve just checked
the inlets. There’s the rpm. Exhaust temp. rising,
we had ignition. Getting warmer,
750°C. And she’s out of the woods. Almost 100 percent, 330°C.
APU running. 45 seconds. Success.
Great. Next up: a nice pattern. We’ve just checked… the high-speed stick shaker, the high speed protection. Now, we check on
the low speed protection. Meaning, we lower
speed until the stall warning. We’ll try flaps up/20/30
until their respective stall zones. Going by gross weight… and flight level… we’ll check
the list… at which speeds
the warning… the stick shaker,
should trigger. And dropping close
to that speed range… the alert
must trigger. If you’re too slow. Airspeed low,
correct.133 mph.
Perfect. Next test at
117 mph. Descending to 15000 ft.Looking good.
117 mph. Set flaps: 20. Later, during regular service
all that has to work. We could trust it will. But that’s not enough.
We need to know. -True.
-And on the test flight… we also check if… engines, shut off
in flight… will relight again. The procedure for this:
first, “idle thrust”. Then wait for
5 minutes. Then the fuel switch –
you know this – …will be cut off. With no fuel,
the engine spins down. Testing in level flight. Set this one to idle. Switching off
auto-thrust. Lever to zero. So the engine…
-Cools down. Cools down, right. We’re flying
“asymmetrical”, now. The plane would
normally fly a left turn. But the “thrust asymmetry computer”
(TAC)… counteracts the left turn… by trimming the rudder… on its own by 6 units. Okay. Shut down
and relight left engine. Fuel control switch: off.
Left side confirmed. Left side cut off. Engine spools down. Left side, fuel control switch.
Left side confirmed. Run! Engine start parameters
are normal. 21… 22… 23…
Crazy. Exactly like on the plane. If all that worked… final test, we fly
on the RAM air turbine. Solely on this generator… and this one
hydraulic pump. Flies perfectly fine. Then we switch
all systems back on… land at home… and call it a day.

    +PilotsEYE.tv Ein ganzer Film über den Arbeitstag eines Piloten wäre doch interessant!
    Vom Briefing bis zur Shutdown Checklist. Kurz-/Mittelstrecke mit der LH A320
    Nur ein Vorschlag 🙂

    Very amazing. Love it. I worked for American Airlines for 21 years on the ramp. Trying to get on with Delta as Flight Attendant. {cabin crew}. I miss working for an airline. it is all I know.

    Wow, I've only seen 3 minutes of this video, but this must be the best channel on youtube?!  Great stuff!

    maybe the bank angle alarms at 35 degree instead of 30 degree and angle pointer is not yellow should be amber…

    I case that airplane is in flight that we need to start an engine is only fuel and spark with out use APU?
