does any EU airline drop V1 to its minimum value, ie VMCG plus 1kt when possible?
Little bit outside the EU, but the answer is NO. For dry runways, we stick to balanced field V-speeds.
Whilst the possibility of utilizing V1MIN exists using VMCG as the lower limit. I have never heard of anyone “arbitrarily” reducing V1=VMCG+1kts.
For example, using the B777 at MTOW
- Min V1 = 157.4 KIAS
- Max V1 = 163.0 KIAS
- Bal V1 = 160.2 KIAS
- V1MCG = 121.6 KIAS at 35.0 DEG C
Minimum V1 is 36kts higher than V1MCG, as this is the minimum speed where the takeoff can be continued, an arbitrary reduction of V1 to V1MCG+1kt will result in that aircraft failing to achieve 35feet at the end of the runway, I would even hazard a guess that it wont be flying at all!
I think that you need to chat with the AA DEC and request further clarification.
