The above-linked page (July, 2014) includes the latest scripts.
my January - February 2014 edition FlightGear landing drill scripts
0.9 series part 2, last file on my system dated 2014/03/12:

and

file.
I'm already on to the 0.9 series. This time, I'm splitting the single script into different files.
See the
directory and zip file
with all of them.
script v0.8.0 (2014 / Jan)
previous script page
- This still has useful stuff, including the Asiana 214 script.
What's New in 0.8.0? / Context
This version combines what I called the "original series" and the "acceleration score" editions. The original acc. score editions assumed non-ILS (acronyms defined below). Now you can press the "n" key while in flight and you'll get all the instrument settings you expect for ILS--FD on, MFD set to APP, FD set to LOC and GS (A/P does not change). "n" also sets visibility to 551m, which you can reverse with the "z" key (lower case).
Page incomplete as of 2014/01/22 8:38am EST. Will continue ASAP.

Weaknesses / Bugs / Future Work
The script is meant for a landing drill where one "appears" in the air to start the FG session.
Some major updates in this edition are:
Acronyms / Dictionary
My script is mainly for the Boeing 777-200ER, but much of this generalizes:
- AGL - distance above ground level, given in feet in the US (not sure if the B777 allows metric)
- A/P - autopilot
- APP - MFD approach setting, showing the runway versus current course--shows to what degree you're heading for a perfect landing
- GS - groundspeed or glideslope
- IAS - indicated airspeed - what the pressure sensors "feel" as airspeed, affected by wind and altitude, as opposed to true airspeed (TAS) and groundspeed (GS)
- ILS - Instrument Landing System: radio beacons that allow the pilot to see up-down and left-right deviation from a perfect landing
- FD - flight director, shows pinkish lines on the primary flight display to line up the glide tunnel--both glide slope (up-down) and left-right.
- LOC - Localizer setting for the flight director and / or the autopilot lateral mode setting. A localizer is a navigational radio beacon.
The LOC A/P setting means head for that localizer.
- MFD - multi-function display - the display to the right of the PFD. 2 of the 4 settings are MAP (a big compass with nav points) and APP
- N1 - Roughly: engine rpm (revolutions per minute) or engine thrust. More specifically, N1 is the speed of the outer fan (front) and turbine (back) of the engine. N1 is expressed on the display (center panel) as a percentage of maximum--one might ascend at 95% and descend at 58% and be at 38% just before touchdown. The engine can reach 108%, but that shows as way in the red zone. Maximum continuious operation (as best I understand) is around 98.5%.
- N2 - The speed of the inner shaft with the compressor and turbine. Expressed on the center panel in several ways, one of which is Exhaust Gas Thrust (EGT) in degrees C. Very roughly, ranges from 700 - 900 degrees C.
- nav points or waypoints - points of longitude and latitude with 5 letter names--DOOOH, ZELLE, DOOLY, RBEKA, BEDRK. These are listed in a catalog (somewhere. It's hard to find an exhaustive, current list). These are the equivalent for road signs for flightpaths.
- PFD - primary flight display - the display directly in front of the pilots (pilot and co-pilot each have one) - IAS, artificial horizon, altitude, etc.
- TAS - true airspeed, as opposed to IAS that
- Vref (or V-ref or Vref) - reference velocity - roughly, the minimum safe speed (IAS) at which the plane can maintain altitude
Miscellany - Throttle Values
I removed the following from the current version, but might be useful for reference:
# to set the throttle:
setprop("/controls/engines/engine/throttle" , aValue0to1); # one engine (left, I think)
setprop("/controls/engines/engine[1]/throttle", aValue0to1); # the other engine (right?)
Values
A value (aValue0to1) of 0.187 = 34.7% N1. 0.2 = 36.2%
