    Default Paul's RVOSD Dream List for next versions! :-)

    such a great little device... here's some things I hope are considered for any RVOSD5 updates:

    Strip tapes on radar screen - if they are no longer on the RVOSD5 options, have them returned?

    Summary page: amps and speed – reqts vs turn off, as I mentioned in another post...

    Altimeter – having an MSL-capable Kollsman option... Be able to not only have the GPS-MSL option, but like real aircraft, be able to set the Baro Altitude to MSL (model field elevation) by atting a berometric pressure for the area, or at least manually setting known field elevation...

    VSI (vertical Speed indicator, or Variometer)– FPM (feet per minute) option, vice feet/second only... I am ruined by flying professionally, so I always intuitively know the feel of a "300 FPM" descent vice a 5 ft/sec one... I don't know if others do this, but the pilots I know who fly RC would love the option, in config, to choose say FPM, FT/SEC, maybe m/Sec (for the physicists out there LOL)...


    Later -

    Having a pitot static option, mostly an Indicated Airspeed, would be wonderful! (and the config options to display GPS and/or IAS)

    Having a small radar altimetr option, I see some people playing with radar altimeters, laser altimeters and accoustic rangers in other blogs - this would be a great future consideration!

    Having the full magnetometer....

    Go crazy and have an angle-of-attack (AOA) indication, in units, or a simple indexer.... probably pie-in-the-sky, but loved them in tactical aircraft!



    FWIW! Thanks,
    Paul

    +1 on the pitot option for static and dynamic pressure

    i think USB data link support, a communication protocol and a PC ground station control SW could be added, even without the antenna tracker function if it's not ready.
    Such Ground station software would act as parameter/waypoint configurator and eventually telemetry display thru audio channel while inflight

    This one is already available! I installed it in mine a few weeks back and it works perfect!
    I used this kit

    This thread shows you how.

    Wow - nice! I hope I can figure the installation out - hardware seems straightforward... how does the firmware handle the pitot static inputs?

    I so want to change the vertical speed to Feet per minute, as well.... I just cannot "think" in the current values :-)

    Meanwhile I ended up with one of these flux compasses from a boat:

    Not at all small - but pretty light for larger planes, and very accurate mag heading - put out by NMEA.... it would be interesting if the RVOSD5 could handle NMEA feeds on Mag heading....

    lol... the sky's the limit he?

    What about a FMS with IAN approach capabilities and a dual coupled auto pilot for automatic cat3 landings...

    Just kidding Alex..

    But I would really like the ft/min option for the vertical speed as well!
    Also a baro setting option for QNH or QFE flight would rock!

    And in the long term:

    An autopilot that uses airspeed as input for throttle setting, in stead of a fixed throttle setting.
    This way, in case the engine would run out of juice before a return to home, the autopilot could trade altitude for speed.
    A speed slightly above the (user set) stall speed.
    It would prevent the plane from stalling by the autopilot that would otherwise try to maintain altitude..
    And if the plane would "go down" in such a mode, it would be at the slowest speed possible with minimum chance for damage to both the plane and the object it hits.

    Maybe something for update 5.08?

    Using airspeed could be problematic trying to get home against a headwind

    Why?

    Actually, you can experiment with your plane at what power (throttle setting) your plane is most "efficient" in terms of battery use.
    The result would be the max endurance airspeed (asuming the weight of the plane doens't change much).
    Or, you can experiment (or calculate) for your plane, what the optimum speed is to travel most range.
    The same for if your engine stops running due to low batt..

    One could choose mode1 for power available with 2 settable speeds: Vmax range and Vmax endurance.
    And mode 2 for no power available (trade altitude for speed - mode) with 2 settable speeds: Vmax range glide and Vmax endurance glide.

    (For info on speeds and such: http://www.eaa1000.av.org/technicl/p...s/perfspds.htm)

    If the auto pilot uses speed management in stead of setting fixed throttle, it would actually give you a better chance to get home if it was critical..

    How about integrating GPS ground speed and track with airspeed from IAS sensor and heading , to give a wind direction and speed arrow ?
