I wonder if it would be possible to add a M0.80 cruise profile for the Citation Longitude?
Would be useful for eeking out those vital extra miles to get across the pond (especially westbound against the Jetstream).
I don’t know if it’s of any use but there’s a ‘flight planning guide’ here which includes consumption figures for a M0.80 cruise in ISA conditions:
https://www.google.com/url?sa=t&source=web&rct=j&url=https://aviav.ru/wp-content/uploads/2020/04/citation-longitude-fpg.pdf&ved=2ahUKEwiR0dOT-cr2AhUSEcAKHVIbB-cQFnoECBMQAQ&usg=AOvVaw2j4unyjIcY_mf-3VIo3hDZ
Obviously not a full performance manual but might be sufficient to allow the introduction of a M0.80 profile?
Thanks in advance!
