REFERENCE INFORMATION (by Aircraft performance

Starting the engines
A step-by-step procedure:
*****Pre-start
check: *****
Check that "low stop lever" is on
"Ground" position and H.P.C levers
are "off", and that neither prop is
feathered. Also check that the prop brake is "off" and parking brake
is set.
Also ensure that the fuel trimmers have been set
correctly.
1. Select the engine you are starting with the
"engine select" switch. Normally No. 2 engine (starboard) is started
first.
2. Switch Starter Master Switch to "start"
3. Push Starter push button.
4. Wait the starter motor to increase engine RPM to
around 1200-1500 RPM, then move the H.P.C lever for that engine to
"on".
5. After ignition, wait for the engine to reach
approximately 4000 RPM, then move the H.P.C lever to H.SWL.
6. Keep your eye on the TGT gauge, and increase the
fuel trim as necessary to keep the TGT below the red line.
7. Repeat the procedure for the other engine
8. After both engines are up and running set
"Engine Select" to "off" and "Master Start"
switch to "safe"
*****Taxi*****
Before taxiing check that the low stop lever is in
"ground" position
and activate W/M injection system (2 green lights).
Disengage the parking brake, then slowly advance the power levers until engine
rpm is around 12000 rpm (be careful not to autofeather
your propellers!).
Once the plane starts moving you can cut back the
power levers to around 11700 rpm for a 14-17 kts taxi
speed.
*****Take-off*****
There are two types: WET - utilizing Water Methanol
boost, and DRY
- without Water Methanol boost. Procedures usually
call for a Wet takeoff when the takeoff weight exceeds 48,000 lbs or when
operating out of runways less than 6000 ft long. It is possible to do DRY
takeoffs if the runway is long enough (around 9000 ft.) even at high takeoff
weights, however, this isn't recommended.
Flap setting for a "wet" takeoff is 10 deg.
Flap setting for a "dry"
takeoff is 15 deg. During a wet takeoff, the engine
speed is 15000 RPM with a TGT of 860° Centigrade. For a dry takeoff, you get
15000 RPM with a TGT of 820° Centigrade. Take note, your only indication of the
power difference between a WET and DRY takeoff is the TGT. However, a WET
takeoff will give you 3,060 SHP, while a DRY takeoff will give you 2,600 SHP.
During a wet takeoff, Water Methanol is sprayed directly into the combustion
chamber once the engine speed passes 14800 RPM. Fuel flow during takeoff is
approximately
1600 lbs/hr/engine. Rotate speed is 105 knots for a
MTOW takeoff,
with a pitch angle of 8 degrees nose up.
*****Climbing*****
Initial climb rate is 1000 fpm. Once the gear and
flaps are retracted, the water methanol system is turned off, and climb power
is set at 14500 RPM with a TGT of around 790-800 °C, fuel flow around 1100-1200
lbs/engine. Pitch attitude is around 8 degrees with an initial climb rate of
1000 fpm. The YS-11 is somewhat underpowered with average climbe
rate for MTOW around 500 fpm.
*****Cruise*****
Normal cruise altitudes are between 8000 and 20000
feet, with cruise power setting of 14200 rpm you get speeds ranging from 160 to
210 kts, engine temperatures should stay below 800°C
with an average fuel flow of 1000 lb/h. Ideally, you should get 14200 RPM and
770°C TGT. You can use the fuel trim controls on the center pedestal to adjust
the temperature together with throttle levers. During cruise the H.P.C levers
are set to "on" position and all of the prop indicator lights should
be off.
*****Descent*****
NORMAL DESCENT
Engine speed is set at 11,000 rpm. Airspeed should be
around 170 knots with a rate of descent between 1,200 to 1,400 ft/min.
*****CRUISE
DESCENT*****
Engine speed set at 14,200 rpm. With a descent speed
of 240 knots, the descent rate is between 1,200 to 1,700 ft/min.
***** Approach
and Landing*****
Joining the traffic pattern downwind, keep the speed
around 140 knots and extend flaps to 10 deg. Turning base, extend the landing
gear. When the landing gear indicator shows the gears fully extended, lower the
flaps to 20 deg. and begin a gradual descent. Turn to final approach at
approximately 600 ft above ground level and lower the flaps to 35 deg at 110
knots. When passing outer marker turn the W/M injection system back on (2 green
lights) and H.P.C levers to "lock
out". Set the fuel trimmers to the pre-calculated
position by referring to the chart on the checklists. Slow to Vref (90-105 kts) over the runway
threshold. Close the throttles fully just before touchdown (aircraft attitude
is between 3 to 5 deg nose up) and when all the wheels are on the ground, pull
the low stop lever to the GROUND (full aft) position. On crosswind landings,
add a 5% increase
in airspeed to the calculated Vref
speed.
