This adds a TACAN instrument to the inventory. Range and bearing are calculated
to the TACAN or VORTAC beacon selected by means of the Channel Selector in the E
quipment/Radio pull-down menu.
A TACAN beacon has also been added to the aircraft carrier Nimitz (channel #029Y
).
Annexed an IVSI (instantaneous ertical speed indicator), which bypasses a
limitation with Concorde :
- the cruise at Mach 2 must be with a slow climb rate of 50/60 ft/min
(2h from 50000 ft).
- with /velocities/vertical-speed-fpm, the real climb rate (altimeter) varies :
One must constantly (every 5-10 minutes) change the vertical speed hold of
the autopilot between 10 ft/min and 200 ft/min.
This is very annoying because not a constant offset : that could be a lack of
sensitivity of /velocities/vertical-speed-fpm (FDM ?).
This new IVSI :
- Is an emulation with works with environment pressure : a real IVSI works with
static pressure (with lag) + accelerometers.
It is not forbidden to later upgrade to the real model.
- Doesn't require a tuning of the autopilot made with
/velocities/vertical-speed-fpm (also tested with 737, 747) :
Concorde's autoland works without update.
directory and over to the Instrumentation directory and make them modular
in the sense of being able to pick and choose what you include with any
particular aircraft.
I've made an encoder and a transponder. The transponder gets C-Mode altitude
information from the encoder. These two might not be very usefull right now,
but I think they might come in handy when the ATC network gets going.
These patches add a clock instrument, which allows to model failure ("serviceable") and to adjust the time independently of the system time (defaults to GMT). The main incentive is to make the p51d clock work and adjustable via the knob.
o Offers a time string ("12:03:15") for the LCD or for LED
clocks, or an empty string in case of failure/power off. The
instrument assumes that digital clocks are battery buffered,
so they will be updated even if there's nothing on the display.
o Offers the number of seconds since midnight for analog
clocks, like in the p51d. This number is not increased
if !serviceable. So the clock will stand still and continue
where it stopped when it's serviceable again.
I did not consider voltage yet, because the Mustang's clock will need a lot more current than the LCD clock. The instrument is updated 4 times per second but returns immediately if neither time nor offset changed. The function getGMTString() in fg_props.cxx could be removed after applying these patches.
for a little while, since it uses different properties. There are
some improvements, especially with searching and range. It also has
its own serviceable and in-range properties, independent of any
coupled VOR.
a spinning gyro.
Changed FGInstrumentMgr to inherit from FGSubsystemGroup, greatly
simplifying the (already simple) class. I should probably rename this
to FGInstrumentGroup or something similar, but not today.
Added the gyroscopic turn indicator (part of the TC).
