Pausing the Climb Example
During the climb to a destination altitude, a controller might ask the pilot to hold at a specific altitude until
further advised. The Pro Pilot can easily accommodate such a request.
Example : Assume that a climb has been initiated to a destination altitude of 8,500 feet. The AS/VS
LED and the ALT SEL LED are flashing to indicate the active profile. If it is desired to pause the climb
at, say, 6,500 feet the pilot may press the encoder button (while viewing any V MODE screen and the
display arrow points to the right) when the aircraft reaches 6,500 feet.
At that point, the Pro Pilot will enter the
ALT HLD mode and the green ALT HLD LED will illuminate to
inform the pilot that the aircraft is holding at the current altitude. The AS/VS LED and the ALT SEL LED
will stop flashing, but remain illuminated (to indicate that the altitude pre-select system is “armed”).
To resume the climb to 8,500 feet, press the encoder knob to initiate the climb and the AS/VS LED and
the ALT SEL LED will resume flashing. The ALT HLD LED will go out.
NOTE
: A vertical rate and target altitude may also be entered prior to engaging the V NAV servo. Once
these parameters have been entered, the aircraft will immediately enter a climb or descent to the
preselected altitude, if chosen, when the
V NAV servo is engaged.
Upon reaching 8,500 feet, the aircraft will resume level flight and the ALT HLD LED will illuminate.
Assuming that the aircraft was trimmed properly for the climb, the display will begin to display a “
TRIM
DN ” alert when the aircraft levels at the “paused” altitude. If the pitch servo is equipped with the optional
auto-trim feature it will automatically re-trim the aircraft.
Changing the Destination Altitude
If the pilot wishes to change the destination altitude, once set, prior to initiating the climb or during the
climb, it is easily done by repeatedly pressing the
V MODE button until on the ALT SEL screen. Rotating
the encoder will then change the destination altitude.
Example: If a controller has cleared the aircraft to climb to 5,500 feet, the pilot might go to the ALT SEL
screen and enter that altitude. If a specific climb rate was not entered, the Pro Pilot will enter the default
climb rate that was chosen in the
CONFIGURATION menu.
Once in the climb, if the controller then changes the assigned altitude to 7,500 feet the pilot would press
the
V MODE button repeatedly until on the ALT SEL screen and then rotate the encoder knob until the
destination altitude reads 7,500. It is not necessary to perform any other action to activate that setting.
A Vertical Flight Scenario
Let’s assume that we are flying to an airport that is about 50 nm distant. Our home airport is located
under Class B airspace with a ceiling of 3,500 ft. Our en route altitude is planned to be 7,500 ft. We
have entered the route into our GPS and (if we have a panel mounted GPS) selected the localizer
approach at the destination.
When we power up, the Pro Pilot asks us to adjust the
BARO
SET screen so that the internal altimeter agrees with the field
elevation.
Rotating the encoder knob will adjust the elevation by 5 ft. per “click”. Once the display altitude agrees
with the aircraft altimeter, press the encoder knob and the screen will advance to the
H MODE displays.
The display indicates that the destination airport is KXYZ and,
since we are still motionless on the ground, the groundspeed
is zero.
