FLIGHT PLAN PROGRAM - ALTITUDE SELECT SCREEN RELEASE 3.10 PAGE 1 OF 3
The Altitude Select screen displays a re-cap of flight log data for each of a
number of altitudes. Its purpose is to facilitate the determination of the
best cruising altitude based on such criteria as minimum fuel burn or minimum
flight time to destination.
The maximum altitude shown can be limited by the airplane's ceiling or by the
maximum altitude that can be reached on a short flight. Also, it is limited to
not more than 17,500 feet for VFR flight.
In the altitude column on the left-hand side of the screen is a solid video
block. It is used to select the altitude for the flight plan display, and can
be moved by pressing the up- and down-arrow keys. Once an altitude has been
selected in this manner, press the F key to go to the Flight plan display.
The RESERVE column on the right-hand side shows the amount of fuel (in hours,
minutes and seconds of time) you will have remaining after the trip. This
figure should depict at least those reserves required by FAA regulations, for
example 0:30:00 (30 minutes) for a day VFR flight. If it is negative, you're
likely to make an unscheduled landing! A flashing number denotes insufficient
fuel reserve.

If you see asterisks ****** where a calculated value should be, there will be
an error message flashing at the bottom of the screen. The most likely cause
of this would be the winds aloft. The next most likely cause would be the
aircraft performance data.
The winds aloft could be valid for certain altitudes, but not for others.
Therefore the presence of ****** for some altitudes but not for others does not
necessarily mean your whole flight plan is bad; it is incorrect for those
altitudes where you see ******. If you have specified winds aloft for only one
or two altitudes, the program has interpolated the winds aloft for all the
other altitudes and it is possible one or more of those may be incorrect.
Entry of incorrect aircraft performance data could also cause this problem.
See the HELP screen displays for WINDS aloft for more information. You can
get there by pressing W from the Flight log screen, then pressing H.
FLIGHT PLAN PROGRAM - ALTITUDE SELECT SCREEN PAGE 3 OF 3
Following is a description of each of the menu functions:
F = FLIGHT plan display. After selecting the altitude, press F to go to the
flight plan display for that altitude. The flight plan display has its own
HELP function for more information.
P = aircraft PERFORMANCE display. Use this function to either change perfor-
mance specifications for the active aircraft, or to change to another air-
craft, or to adjust temperature for density altitude computations.
T = TRIP display screen. This function will display the active trip and allow
you to add or delete waypoints or to select a different trip. WARNING: all
of your winds aloft data will be lost when you go back to the trip screen.
Winds aloft information is not stored on the disk.
O = OUTPUT to the printer. You will get the "Is the printer ready" prompt.
Make sure the printer is on line, then respond Y (for Yes) to print, or
N (for No) or press the Esc key to cancel the output function.
H = HELP - displays the explanatory information you are reading now.
