today I perform Flight KDEN-KMIA in the A321 version 22.214.171.124
Activesky weather from today 12April 2020, 0033UTC
Takeoff from Rw25 (12,000Ft / 3658m) Full Length,
and was left with just 500Ft of runway left after Vr
Autothrottle in TOGO mode. FMA shows mode is armed SRS and RWY.
Alpha floor protection ALMOST kicks in.
Aircraft really does struggle to gain speed now.
Climb to 10,000Ft with Flaps 3
aircraft starts to gain speed with very slight change in attitude. Like magic thrust out of no where.
- weather conditions: KDEN 112253Z 31006KT 10SM SCT090 SCT150 BKN220 21/M10 A2955 RMK AO2 SLP948 T02061100
- winds: 310/6
- temperature: 21.00 celsius
- runway(s): 25
- altimeter: 29.95
Fuel: 15,675Kg (31,912Lbs)
With only 500Ft of runway left this doesn't seem correct, even for this high an altitude runway 5434Ft
I have performed this flight many times before with the A321 in previous versions before 126.96.36.199,
in the same conditions with plenty of runway left to spare (normally left with 4000Ft runway spare after takeoff) .
By the end of the threshold today I was only 120AGL!!!
Is the performance data correct for high altitude airports?
It felt like engines did not have correct power.
