What are you
going to fly?
The Piaggio P-166 is a light, small twin. The first P-166A flew in 1957
and today the P-166DP-1 is the latest turboprop evolution. What made
the P-166 popular since it’s first days was it’s
amazing comfort. The interior cabin lets you just stay in feet inside it. This
feature appeared later only in the ‘80s with the concept known as
“Wide-bodies”. It was a great performer too: a nice great MAX speed for its
kind at it’s time: It almost reached 190 KIAS. The P-166 is a derivative of the
amphibian P-136, so it’s well fitted to resist corrosion and hard stress. The
P-166 made it well even in the hard weather of
Piaggio P-166
Main Characteristics (common to all versions):
Take Off:
After you’re lined up with the runway, check space around the plane is
free of eventual obstacles. Apply 10° flaps, push the throttles to 100%, and
wait for the plane to reach at least 80 KIAS. Gently pull back the stick and
wait for the wheels to leave the ground. The aircraft will lift off at around
85 KIAS. Check you’re clear, and retract flaps and landing gear. Climb at the
ideal speed, 80% throttle at least.
You’re done! Good flight.
Landing:
The first thing to keep in mind here is your airspeed. Slow down by decreasing
the throttle, and at around 150 KIAS lower 10° flaps. This will slow you down a
little more, correct your descent rate (due to the flaps lift) and lower the
flaps as you loose speed, until they are fully deployed. Now
when your flaps are fully down give a little of power to maintain a speed
between 85 and 95 KIAS. Lower the gear and check all the wheels are down
and locked. If you’re landing following an ILS this attitude is the best for a
correct glideslope. When you’re at about 10 feet
above the ground, power back to idle and pitch the nose up. The aircraft will
touch the ground at around 65-75 KIAS. Avoid the speed going below 60 KIAS, or
the consequent stall will be fatal. If you are attempting to land in a very
short space, cut the throttle back at 0% at about 20 ft from ground. The plane
will speed down at almost 60 KIAS, and touch down at 55 KIAS. Be Careful: if
not done well, this manoeuvre can easily turn you into a stall.
