I´m having a hard time understanding how said departure works, based on the data given in the plate!
With the initial climb to be more precise… Can someone help me with it?
It says that you ned a climb gradient of 3,3% (200 ft/nm) to cross abeam Kelvin Heights at or above 5500 ft. Now, Kelvin Heights is roughly 2 nm from the end of rwy 23 (which sits at an elevation of 1160 feet). So how on earth am i supposed to be at 5500 when 3.3% equals a v/s of 500 fpm @ 150 kts???
Or are the 5500 to be established AFTER the init climb segment, when crossing abeam Kelvin Heights again (because of it being a 360)?
Am i making any sense here?
3.3% min. height category would do a left turn after reaching 1600ft, circle back around to the airport to gain height (VFR), join the QN 215 radial outbound and cross Kelvin Heights at or above 5500ft.
What plane are you flying? Wouldn’t it be better to climb at closer to 100 knots and 577fpm to go straight out?
thanks for the reply!
Okay, then it´s like i expected it. I was a little confused by how this is phrased in the text box “5500 abeam kelvin heights. Turn left …” as this to me sounds conditional, like in " 5500, THEN left…". Using any kind of jetliner i think i would be requesting a straight out departure…
Then again: shouldn´t there be a climb gradient so i would know if I can make the 5500 abeam kelvin heights on a straight out departure?? 4000 feet within a 2.2 nm distance seems pretty steep to me…
Actually, looking at the chart again, both takeoff profiles would need to do the circle. If you look at the chart picture again, the 3.3% and 5.7% climb profiles are given 200ft/nm and 350ft/nm respectively. Measuring 5nm from QN VOR along 213 radial is only 2.4nm from the end of the runway. That means these climb profiles only result in almost 500ft and 800ft gain in altitude. Runway is 1171ft ASL, so that is almost 2000ft, not 4100 or 5500ft.
Look at the VAPLI2 departure chart which has much clearer instructions, including same left turn around Dear Park.
Yeah, i think a straight out departure is not possible if 5500A abeam Kelvin Heights is a restriction.
No problems interpreting VAPLI2, as it´s indeed much clearer. I think the FKN8 suffers from the unfavorably drawn initial climb inset plus the fact that it mentions initialising the left turn right after saying 5500 at Kelvin Heights…
4000 feet within a 2.2 nm distance seems pretty steep to me…
