MJC8 Q400 landing speeds card, incomplete data?

edited July 31 in Customer support

Only recently I realized that we are specifying incomplete data on landing speeds(from the cards that are included when buying the product) ...

If you look at the landing cards, we only have the speed of Vaap Vref and Vga, but required on only Vref and Vclimb...
This is described both in FCOM and in the official application for calculating the take-off and landing paramters as well as in the well-known aurasim...

As I understandVapp Vga we do not set these speeds, just remember them?
And where can I get Vclimb for landing speed (necessary if we go around) especially for flaps 35?

  • I found this in the Majestic docs - Performance Manual.

    "If a VREF (or Derived VREF) table is provided in the checklist, the VREF (or Derived VREF) for planned aircraft weight and ice protection level will be bugged using the solid bug and will be the only bug used.
    The bug will be flown for approach, landing and go-around to acceleration altitude.
    Bombardier and AeroData assume that an abnormal/emergency checklist will terminate with a safe landing. This is the reason that no VGA, VFRI or VCLIMB speed is provided.

    this is unexpected, probably this is an old SOP, I couldn't even imagine it :p

    that is, it turns out that at speed Vref( the data from MJC8 Q400 landing speeds card) we can set the flaps to 0 (in case of go-around)? and started go-around, or how are we looking for a safe speed(VFRI), in the event that we have not set a bug for this speed? :(

  • Since we are in a simulator; Lets assume the airport is at or near sea level, the temperatures are above 20C, the aircraft landing weight is 57000 lbs, flaps 35 degrees, the chart shows VRef=116 kts.
    During a go-around, the pilot would immediately retract flaps to flaps 15 and retract the gear. The take-off chart shows a Vfri= 125 kts for 57000 lbs and flap 15 degs. It would be OK to begin retracting the flaps at that speed, and continue retracting the flaps according to the flap speed placard on the pilot side window.

  • that's how it really is!
    I thought why there is no speed data for flap 35, for sure, if we go around, we immediately flaps up to 15!

    but in the end, we use not only the speed of the Vref :)
    it seems logical to set a bug Vfri in advance o:)

  • You could set the bug, or just remember Vref+10 kts.

    As a reminder;

    Flaps Extended Speed (VFE)
    Flaps 5°. .................................................................................... 200 KIAS
    Flaps 10°. .................................................................................. 181 KIAS
    Flaps 15°. .................................................................................. 172 KIAS
    Flaps 35°. .................................................................................. 158 KIAS

    I just want to add that after set the flaps at 15 and reaching the acceleration altitude of the flaps, we set immediately to falaps 0, without intermediate positions (10 and 5):

    To initiate a go-around, PF presses the G/A Button, advances the power levers and
    smoothly adjusts the pitch to the FD which should be at 9°, calling “Go-around, Set
    Power, Flap 15”. PM places the Power Levers in the Rating Detent calling “Power
    Set”, sets or confirms Flap 15° calling “Flap 15” and, when both the Altimeter and VSI
    indicate a positive climb, calls “Positive Climb”. PF then calls “Gear up, Heading,
    Altsel”. PM selects Gear up followed by HDG and ALTSEL Modes calling to confirm:
    “Gear up, Lights out, Heading/Altsel selected”. PM confirms that the correct G/A
    altitude is set.
    The application of full power for the go-around will tend to make the aircraft pitch up so
    PF must maintain the correct pitch attitude to prevent excessive rate of climb –
    particularly at low weights.
    During the climb to AA, PM advises ATC of the go-around and reminds PF of the
    Missed Approach Procedure. At AA (1000 ft AAL), PM calls “Acceleration Altitude”.
    PF calls for in turn:“Flap Zero”, “Autopilot engage”, “Bleeds On/Norm”, “Set
    Climb Power 900”.
