Flying the EMB-110
--------------------
Notes:
The airspeeds given are indicated airspeeds (IAS) so you will need to
select this option in the 'options', 'preferences', 'instruments' menu.
Takeoff and climb data is for the aircraft at maximum takeoff weight.
The throttle settings are given as n2 readings, this corresponds to the
'turb' meter on the learjet panel.
The flight model was designed using a more realistic temperature
gradient than the default weather provided by fs. The Outside Air
Temperature (OAT) should decrease by 3.5 Farenheit (2 Celsius) for
every 1000' of increased altitude. So if the temperature at sea level
is 59F the OAT at 40,000' should be -81F not +14F as the program
defaults to. Flying with the default temperatures will cause a marked
decrease in the aircrafts performance and range.
I have adjusted the maximum fuel available to allow for a typical
payload of passengers or cargo. The maximum fuel is now 276 galls
which I estimate will give you 2 hours flying at maximum speed or 3
hours at the economical speed (plus fuel for 45mins holding, a 50nm
diversion and 5% reserves). If you want to fly with the full fuel
load change the fuel capacity to 464 galls and reduce the payload to
give an MTOW of 12,500lbs.
The aircraft has been test flown after conversion to fs95 and flies
as per the numbers below.
Take off:
Apply 1 notches of flap. Open the throttle to 95% n2 and rotate at
100kts. Gear up on positive climb and aim for the initial climb to
be at 115kts. As the speed passes 120kts remove the flap.
Climb:
Maintain the throttle at 95% n2 for the climb. Trim the aircraft to
climb at between 130-135kts IAS, initially this will give a climb rate
of about 1700fpm and if you get the trim right the aircraft will hold
the airspeed and slowly reduce the rate of climb without any further
pilot intervention.
Cruise:
The service ceiling is 22,500' however as the aircraft is unpressurised
it could be uncomfortable for passengers and crew at that height so
cruise between 6,000' and 15,000'. Level off and reduce the throttle
slightly and let the airspeed build up, cruise with the power set to
90% n2 for the maximum speed of 220kts TAS or 83% n2 for the economy
speed of 180kts TAS.
Descent:
Throttle back almost to idle and lower the nose to start the descent.
If you set the autopilot altitude to the desired altitude and put the
'altitude hold' on you will descend at 1650fpm, adjust the throttle to
keep the airspeed at around 165kts IAS
Holding/Approach Pattern:
Increase the throttle to 82% n2 to hold the airspeed at 165kts IAS.
Landing:
Add 1 notch of flap and start the approach, adjust the throttle to
avoid the speed building up too much. Gradually add more flap and
lower the gear, adjust the throttle to aim for 90 to 100kts at touchdown.
Flight Sim data
---------------
The following data was collected during my test flights. You may find
it useful for programs such as Navigator and adventure creators which
want climb and descent rates with true airspeeds and fuel flow figures.
Taxiing
Fuel burn 6 gals
Climb to 10,000'
Average climb 1500 fpm
Average speed 140 kts TAS
Fuel burn 138 gal/hour
Cruise at 90% n2 (220kts TAS)
Fuel burn 86 gals/hour
Cruise at 83% n2 (180kts TAS)
Fuel burn 57 gals/hour
Descent (using a/p alt hold)
Average descent 1650 fpm
