Boeing 737-300 in X-plane 11

This is a work-in progress, once complete it will be converted from a blog post into a web page.

The 737-300

After the success of the 737 original series, Boeing designed the -300 as the first of the second generation, or more commonly known as the ‘classics’ series, which first flew in 1984.

The main improvement over the originals is the CFM56, high-bypass turbofan engine with better performance and fuel consumption and compliance with the new ICAO stage 3 noise regulations.

Also the flight deck was upgraded to include four colour CRT screens instead of analog flight instruments.

It can carry up to 149 passengers over a range of 1000 nautical miles, or about 120 passenger over a range of 2200 NM. More than 1000 aircraft of the -300 series have been sold, making it one of the most successful airliners ever built.

It was in production until 1999 when it was replaced by the -700 series of the Next Generation. In 2017, about 400 aircraft are still in operation.

In this virtual ‘type rating’ course in X-plane 11, we will be using the “737 Classic by IXEG”. It is a high quality payware add-on for x-plane 10 and 11, representing the -300 passenger variant with the 20k rated CFM56 engines.

Software

Official website: http://ixeg.net/
on X-aviation: http://www.x-aviation.com

At the moment of writing, the current version is x-plane 11.05 and IXEG 737 classic version 1.2

The procedures described are the ‘post 2005’ or ‘new’ procedures and updated with the 2006 and 2007 enhancements. Only use this guide for the simulator and not in your real 737. (just in case that you have one…)

Installation:

Installation in X-plane 10 and 11 is straightforward. During the installation you can choose to install a few different airline liveries as well.

After installing, you need to add an empty folder named “coroutes” in:
…X-Plane 11\Aircraft\X-Aviation\IXEG 737 Classic

In his location, FMS company routes will be stored.

coroutes

Compatible add-ons:

  • the Better Pushback utility is compatible, and highly recommendable with this aircraft
  • The RAAS utility is compatible as well
  • You can choose to update the FMS database from Navigraph (Payware)

Start up x-plane and you’ll be automatically prompted for activation.

Joystick setup:

The IXEG comes with it’s own custom joystick button options. At the minimum assign a button for the following (and found in the real aircraft here:)

IXEG/733/Autopilot/Disengage AP (on the yoke)
IXEG/733/Autopilot/Disengage AT (at the side of the thrust levers)
Engines/Basics/Engage TOGA power (on the top of the thrust levers)

IXEG options and setup

You can access the IXEG main menu by moving the mouse to the left side of the screen.

Hints & tips menu

are just that. have a read through if you wish.

Preferences menu:

In the visuals menu you can turn on and off several visual settings. Note that  the ‘draw vortices’ can be heavy on the GPU and reduce frame rates on some computers.

the Use ‘Steam gauge’ setting changes the engine instruments from digital to analog.

Under Misc you can set the Joystick CWS deadzone. CWS is a semi-automatic autopilot function which is hardly ever used, but here you can set the deadzone for the joystick. The default value is 0.10%

Under advanced you can choose between Kilograms/tonnes for European carriers, switching this off changes the cockpit in pounds for US carriers.

Preflight menu

Choose between cold and dark, turn around or ready to fly settings. Although an airline  flight crew would normally find the aircraft in the turn-around situation, for the full tutorial we start with cold and Dark

Quick fuel planner works good enough for simulator use. add a few track miles if you expect a headwind. for example, two hours with 40 knots headwind, add 80 NM to the distance. I would recommend a minimum of 5500 kg for flights shorter than 500 miles.

You can set the aircraft fuel and weight here, but I’d prefer to use the next menu, ground services

Ground services menu

Connect the ground power unit here. you can set the fuel and payload as well. using this menu will make sure that the fuel is correctly distributed in the tanks.

Observe weight limits (737-300 Basic GW, CFM56-3C-1, 20,000lb/86)
Max take-off 56.47t
Max Landing: 57.71t
Max Zero fuel: 47.62t

Note the Elevator trim setting, corresponding with the Cog in % MAC (Mean aerodynamic Chord) a MAC value of 21.0 would be ideal.

Cabin Crew menu

Here you would be able to open the doors, however it does not work at the moment.

View presets

can be accessed either via the menu or by holding the mouse in the lower left corner of the screen.

Failures menu

Gives you the option to fail or repair systems and recharge a drained battery.

After the checks is a good time to do the first flight of the day briefing (Captain).

During the take-off, If you see anything non-normal, please call it out as clearly as possible.

Below 80kts I will abort for any malfunction, after 80kts only for
– fire or fire warning
– engine failure
– predictive windshear warning
– or if the airplane is unable to fly.
Before V1 I will call “STOP”.
My Items, A/T disengage, Thrust Lever close, Speedbrake up, Emergency Reverse.
Passing 60kts You inform Tower: “Tower, BER118 stopping due to…
After Full Stop, I will stow the Reverser, set Parking Brake, Speed brake down detent, Inform the Cabin via PA: “ATTENTION CREW ON STATION; ATTENTION CREW ON
STATION”
Then we will assess situation and perform the memory items as required.

If EVACUATION is NEEDED we will perform the EVACUATION CHECKLIST
Otherwise I will call “CANCEL ALERT, CANCEL ALERT”

If anything happens after V1, we will continue the take-off with at least V2 speed. No actions below 400ft except silence the bell and gear up on my command.

At 400ft, “Heading select”, “Identify” you say what you think what the problem is, and I agree, you can perform the memory items if required.
The engine out procedure is continue runway heading 3000ft and then turn left to TRN.
Acceleration altitude is 1566ft, “SPEED 210” and I will accelerate to 210 knots, retract flaps on schedule. at 210, select max continuous thrust. perform the non-normal checklist and inform ATC that we request vectors for an ILS approach to runway 30.

Any questions so far?

Continue after receiving the final load sheet and departure clearance.

plan push back maneuver in better push back utility

We are on stand x, push in x direction, start engine 1 or 2 first. taxi out, first turn to the Left/right for runway X

It is your/my take-off ->

Standard take-off, at 400ft Heading select, at 1566ft, “Level change,  speed 210 and climb thrust”. Retract the flaps on schedule. At TRN radial 024 we’ll turn left to intercept the 198 inbound.

Known issues with the IXEG 737:

As good as it is, this beautiful piece of software has a few known issues:

  • When the centre tank pumps are on, the APU draws fuel from the wing tank which is not transferred from the centre tank
  • FMS functions that are not working:

Trouble shoot

If you cannot save a company route and see PROBLEM SAVING FILE in the Scratch pad, you need to add an empty folder “coroutes” in:
…X-Plane 11\Aircraft\X-Aviation\IXEG 737 Classic

Problem saving route B733

 

Takeoff warning

If you have a take-off config warning, it means that either:

  • Flaps are not set
  • Trim is not set
  • Auto brake is not in RTO
  • Speedbrake is not down

In X-plane, if you have assigned a joystick axis for the speed brake, it may be necessary to move the speedbrakes to the down position with the mouse to stow them fully.
