As soon as the waypoint is selected the HOLD page to modify the holding opens.
• FIX ENTRY // LSK 1L
Indicates the fix / waypoint where the holding is added
• QUAD / RADIAL // LSK 2L
Indicates the quadrant and radial. The quadrant specifies the orientation on where the inbound and
outbound leg are situated relative to the fix. Imagine a holding around SAMPLE VOR; you are
approaching the VOR with a heading of 000°. A northern quadrant indicates that after passing the
VOR you continue along the heading as long as the selected leg time and then start the turn. The
inbound and outbound leg are both north of the VOR.
In case you select a southern quadrant, you start turning as soon as you have passed the VOR – so the
inbound and outbound leg are both south of the VOR.
The radial provides the heading for the outbound leg (when approaching a VOR with a heading of
000° you’ll expect most likely a radial of 180).
• INBD CRS / DIR // LSK 3L
INBD CRS is the inbound course, when approaching the fix where the holding shall take place. In our
example 000°.
DIR provides the turning direction – either L(eft) or R(ight).
Changes may be entered by entering XXX / L or XXX / R into the scratchpad and then press LSK 3L,
where XXX is the heading of the inbound course.
• LEG TIME // LSK 4L
LEG TIME is the amount of time for the inbound and outbound leg. The default is 1 to 1.5 minutes
depending on the speed.
• LEG DIST // LSK 5L
The LEG DIST is the leg distance – can be estimated by multiplying speed and leg time.
• FAA/ICAO // LSK 1R
Indactes wether FAA or ICAO standard holdings are flown. Pressing LSK 1R lets to toggle between FAA
and ICAO.
• MAX KIAS // LSK 2R
Shows the speed flown throughout the holding
