My procedure for EGLL to KJFK, route
https://skyvector.com/?ll=46.3256889725 ... MRN%20KJFK- take off from EGLL 27L with maximum take off weigth with 93 tons of fuel with afterburner
- afterburner OFF after 90 seconds
- climb to FL300 with 3000 fpm, then accel to 380 KIAS
- manage fuel - fuel from tank 9 to tank 11 and to tanks 5 and 7, when 9 empty, fuel from 10 to 5 and 7
- afterburner ON over KESUP, climb to FL600 with maximum allowed speed (checker needle on Air Speed indicator), afterburner OFF at M1.8 - M1.9, accel to M2.06 with Total temperature 128 deg. C on the instrument on pedestal
- cruise level FL600 M2.06 to 20 miles before KENDA, manage fuel, transfer from 5A to 5 and from 7A to 7
- descend to FL100 with -4000 fpm, decelerate to 250 kts, continue descend to 3000 feets for final approach, visor down, nose full down
Autoland procedure
- catch localizer at 2500 feets AGL
- wait for GS indicator on HSI
- press LAND, then GLIDE button on AP, hand on yoke and throttle
- 100 feets AGL AP OFF
- 15-20 feets AGL A/T off, slam throttle to full forward, then to idle
- land with attitude 10 deg at 160 kts when 19 tons FOB, don't attempt autoland with more than 30 tons FOB, You will stall and crash. It is possible to land with 90 tons FOB, but on realy long runway with touchdown speed 230 knots
NZWN to KJFK in 6 hours is impossible. Concorde's standard maximum range is 3700 nm with cruise climb from FL510 to FL600, 4100 nm at FL600 with safety reserve, 4300 nm FL600 in very ideal weather and without subsonic cruise, without reserve at FL600 4700 nm. I was able perform flight from SBGL to LFPG - 5100 nm at FL640 M2.00 without subsonic cruise (check
https://fgtracker.ml/modules/fgtracker/ ... ID=6930405 or
https://fgtracker.ml/modules/fgtracker/ ... ID=7023667), but landed on fuel vapour without possibility for second attempt. I took off with 94.5 tons FOB (max fuel config with out of CoG limits). Real longest Concorde's flight was from SVMI to LFPG or FLPO, it is 4100 nm, again, it was in very ideal metheorological conditions and with almost no pax and cargo. In FG is not absolutly perfect simulated atmosphere at high flight level, especialy jetstreams and temperature. As result is aircraft's range bit longer than in the reality.
