TAKEOFF
Taxi onto the runway and get lined up. Verify that you’ve got
the flaps set at 15 degrees and that the trim is set for takeoff; if it’s
outside the takeoff range you’ll see the ELEV/AIL TRIM light on the
main annunciator panel. All the annunciators, including those in
the roof, should be off at this time; you’ll probably still have the
main air valves on, so turn them off now.
In the real airplane, you’d grab the nosewheel tiller in your
left hand and use your right to set the power levers near takeoff
power. As you start to roll, the copilot will hold the yoke forward
(for better nosewheel steering). Since the electronic engine com-
puters (EECs) automatically adjust takeoff thrust based on air tem-
perature and altitude, you don’t need to make finicky power adjust-
ments-just move the thrust levers smoothly all the way forward. As
the ASI stirs from its peg, the copilot will call “airspeed alive.” At
some predetermined value - often 80 knots - he’ll verify that both
ASIs are reading the same and say, “80 knots, crosschecked.”
By now, if not before, you’ll have adequate steering through
the rudder pedals. As you let go of the tiller and move your hand
to the yoke, you’ll call “my yoke” and the copilot will let go of the
yoke on his side. At V
1
the copilot will call it out. Since you know
you must continue the takeoff from this point, you may elect to
take your right hand off the power levers. At the “rotate” callout,
raise the nose to about ten degrees.
Typically, it’ll take more of a pull to start the nose up than to
hold it, so be ready to relax back pressure partway as you near
your pitch target. The airplane will trundle along for a couple
more seconds before lifting off. As the altimeter and VSI start to
show a climb, the copilot will call “positive rate;” your response
is “gear up, yaw damper on.” Meanwhile, you’re adjusting the
pitch attitude to accelerate past V
2
. The airplane will gain speed
quickly; you’ll probably need to be pretty active on the trim. As
soon as the gear is up, turn on the #1 and #2 MAIN AIR VLV
switches, one at a time - if you wait, the airplane will already have
climbed a few thousand feet, and there’ll be a real “ear bump” as
the cabin pressurizes.
