The Swedish built Saab 340B is a twin turboprop short-haul commuter 
airliner with accomodations for 30-37 passengers. This aircraft N252CH 
is operated by Chautauqua Airlines, a regional carrier for USAir 
Express. 

What's new for version 2.0:

* Immproved textures (more accurate color rendering). 
* Landing light definition file included.

Saab 340B
---------
The 340 began life as the SF340, a joint venture between Saab-Scania
and Fairchild, in the early 1980's with the first production models
going into service in 1984. In November that year Saab took over full
responsibility for the aircraft following Fairchilds decision to move
out of aircraft production, the SF340 designation remained for a time
but was eventually changed to 340A. The 340B offers more powerful 
engines to improve the 'hot and high' performance, an increase in
the maximum takeoff weight and improved range, it was delivered in 
September 1989.  


Power		  2 x 1750shp General Electric CT7-9B turboprops
Cruise speed
   Maximum	  285kts TAS
   Long range     252kts TAS
Range             805nm	(max cruise with full load and reserves)
		  935nm (econ cruise with full load and reserves)		
Service Ceiling   FL250
Max takeoff wgt	  28,500lbs
Max Speed         Mach 0.50
Stall Speeds      110kts (clean) 85kts (full flaps) 


Flying the Saab340B
-------------------
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.

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
115kts. Gear up on positive climb and aim for the initial climb to 
be at 130kts. As the speed approaches 140kts remove the flap.

Climb:
Maintain the throttle at 95% n2 for the climb. Trim the aircraft to 
climb at 170kts IAS, initially this will give a climb rate of 2000fpm 
and if you get the trim right the aircraft will hold 170kts and slowly 
reduce the rate of climb without any further pilot intervention.

Cruise:
The service ceiling is FL250 however as the aircraft is used on short
haul commuter routes it will normally cruise under FL200. Level off
and reduce the throttle to 90% n2 for the maximum cruise speed of
285kts TAS or 87% n2 for economical cruise speed of 252kts TAS. The
IAS value will depend on your altitude.

Descent:
Throttle back to 65% n2 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 1750fpm at just over 200kts IAS.

Holding/Approach Pattern:
Increase the throttle to 78% n2 to hold the airspeed at 180kts IAS.

Landing:
Maintain the throttle at 78% n2 and add 1 notch of flap to reduce the 
airspeed and start the final descent. Gradually add more flap and lower 
the gear, with full flaps and gear down adjust the throttle to cross
the runway threshold at between 120kts.  


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	   8 gals

Climb to 19,000'
	Average climb	1520 fpm
	Average speed	 194 kts TAS
	Fuel burn	 233 gal/hour

Cruise at 87% n2 (252kts TAS)
	Fuel burn	 113 gals/hour

Cruise at 89% n2 (285kts TAS)
	Fuel burn	 131 gals/hour

Descent (using a/p alt hold)
	Average descent	1755 fpm
	Average speed	 248 kts TAS
	Fuel burn	  58 gals/hour

Holding
	Fuel burn	  91 gals/hour

Fuel Capacity		500 gals
Reserves		  5%
