FlightGear - Flight Simulator FGAddon

Harrier-GR3/Systems/Autopilot.xml: various improvements.

Increase maximum target pitch to 20; useful at low speed.

Don't use *-trim flight controls. These were being left with non-zero values,
which then prevented other autopilot controllers from working properly.

For ailerons and elevators, incrase Kp at lower speeds, where faster movement
is needed. For elevators, also increase range to full +/-1 at lower speeds.
slowed down aileron movement slighly.

Reduced throttle gain to make things work more smoothly.

Deactivate auto-pilot if any wheel is touching the ground. This allows one to
(crudely) land using just the autopilot (in heading control and vertical speed
mode) with the arrow keys. Also deactivate if we are in replay mode to stop
visual fluttering of control surfaces when replaying.

Harrier-GR3/Nasal/autohover.nas: minor cleanup.

Harrier-GR3: show brief auto-hover info in HUD.

Also alt-d cycles {off, brief, full} display of auto-hover status in main
window.

747-400: delete unused files

SpaceShuttle milestone 12 merge from trunk 4357-4538

SpaceShuttle milestone 12

November 2019 Stable Release notes (by GinGin, see https://forum.flightgear.org/viewtopic.php?t=36618&p=357404#p357404)

New release that can be downloaded directly on the FG launcher

It is coming as usual with nice manual additions : http://www.science-and-fiction.org/bookstore.html

Changes

-New drag coefficient for atmospheric flight, even closer to reality performances for ascent ( benchmarked against real datas of first stage flown)
-New J3 non spherical gravity adjustments for target on Orbit for better rendez vous experience
-Improvement of Shuttle Dry weight taking account of real datas for equipment ( cryo tanks weight, ..)
-Body flaps implementation ( allowing trimming and elevons load relief)
-Better shuttle behavior in case of central engine failure

For very low fuel in the ET, the engines were unable to vector through the CoG, leading to loss of control (like in reality, very exotic situation)

-Rework of Cape Canaveral, high degree of fidelity compared to Google Map ( Lego custom scenery) https://github.com/legoboyvdlp/Florida-fg-CustomScenery Unzip anywhere and specify the correct link in Add Ons
-Hubble ( Thanks to Wayne)
-Better plasma effect during Re entry
-Improvement of many small things on PFD
-Graphical improvement of Display screens

New Failures

-GPC failures, with now the possibility to have a vote between them to detect the failed one
-Crack windshield and depressurization

Scenarios
-Scenario available in game to quickly access a particuliar situation ( Prox Ops, ISS docking, Satellite ..)
-New entries within Mission file : Custom shape for stage 1/2 display ( Ground speed vs pitch angle), Adjustable nominal throttle

New features

-Payload Grapple and retrieval
-Once the Rendez Vous is completed, Eileen is available as a copilot to perform Station Keeping while you are playing with the RMS or taking pictures
-Cue Cards on velcro ( customisable)
