FLIGHT PLAN SYSTEM - FLIGHT LOG SCREEN         RELEASE 3.10         PAGE 1 OF 4

The flight log screen displays a flight log for the altitude selected pre-
viously from the altitude select screen. One of the waypoint names on the left-
hand side of the screen is shown inside a solid video block.  You can move this
video block to any waypoint name by pressing the up- and down-arrow keys.  The
purpose of this is to select an individual trip leg for detailed winds aloft
analysis (see the W function described on the next screen page).

The leg in which cruising altitude is reached is shown on two separate lines.
The first of these two lines represents only the climb portion of the leg and
has the word "(climb)" as a waypoint name.  This line cannot be selected with
the solid video block.  The next line represents only the cruising portion of
that leg, and that line CAN be selected with the solid video block.

If you see asterisks ****** in place of a calculated value, there will be a
flashing error message at the bottom of the screen.  The most likely cause of
this is winds aloft.  See the HELP screens for WINDS aloft for more informa-
tion.  A wind aloft cannot exceed 2/3 of the true airspeed at any altitude.
This problem could also be caused by incorrect aircraft performance data.

Typing one of the following letter keys will invoke the corresponding function:

A = ALTITUDE select. This function will take you to the Altitude Select screen,
    which has its own menu with a HELP function for further information.

W = WINDS aloft analysis. This will take you to the winds aloft analysis screen
    for the selected trip leg.  The winds aloft analysis screen has its own
    menu with a HELP function for further information.  It allows you to change
    the winds for the selected individual leg, and to dynamically analyze the
    effects of those changes.

V = VFR/IFR switch.  This function switches your flight plan from VFR to IFR or
    vice versa. All altitudes will be changed by 500 feet, and all calculations
    will be re-done, but the winds aloft will remain the same.  It will then
    take you to the Altitude Select Screen where you can select a new altitude;
    after that you will be returned to the flight log screen.

O = OUTPUT to the printer.  Press O (not zero) to get this function.  The "Is
    the printer ready" prompt will appear.  Make sure the printer is on line,
    and then respond Y (for Yes) to print.  Or you can respond N (for No) or
    press the Esc key to cancel the OUTPUT function.

    The OUTPUT function gives you a filled-in flight log form for the selected
    altitude, with space to manually enter actual figures during your flight.
    The flight log is followed by a list of waypoints with their corresponding
    lat/longs and other information for your LORAN or other navigation system.
    If your flight has only four or five legs, you can print the altitude
    select screen on the same page with your flight log.

    Note that VHF Navaid frequencies which are on .025-mhz. boundaries will
    have the last digit missing.  For example 122.975 will be shown as 122.97.
    This is consistent with the way these frequencies are displayed on most
    VHF aircraft communications equipment.

P = PERFORMANCE.  This function allows you to change the surface temperature,
    cruising power setting or other performance-related items for the active
    aircraft.  You can also switch to another aircraft, without losing the
    winds aloft or trip data.  The Performance screen has its own HELP function
    for more information.

T = TRIP display.  This function allows you to add or delete waypoints in the
    active trip, or to select another trip.

H = HELP.  Displays the explanatory information you are reading now.

Q = QUIT and return to DOS.

WARNING: When you QUIT or exit to the TRIP display function, all winds aloft
data will be lost.  Winds aloft data are not stored on disk (and shouldn't be,
as they can be very changeable even from hour to hour).  But you will NOT lose
winds aloft by switching to another aircraft or by changing performance data.

NOTE: If you want to go back to the Master Menu screen, press T first to go to
the TRIP display screen, then EXIT from there.
