LVTO trained.
Wet Runway EFATO at V1 split from Vr by 15 kts. RVR 125 m, cockpit cutoff angle only provides 4 centreline lights remaining. No real sense of heading, only limited visual cues for lateral displacement. With about 5 deg NU nothing to see. Instruments.
Another exercise, loss of visual reference at V1 minus 20 kt. Nothing to see again, instruments during the roll.
Any normal night departure facing open sea, all black from about 10 deg NU. Nothing to see,...... you know where this is going
At the top of the thread someone mentioned, IIRC, the angles from the type involved:
8.9 for tailscrape
8.5 maximum
8.0 normal unstick
stunningly thin margins.
BTW does the T7 involved have some flaps auto-retract / relief feature for high speeds at take-off?
