I would agree if the aircraft was flying below the min maneuver speed for the configuration.
If we are looking at the takeoff, we are looking at whatever AFM V2 schedules are available. Min manoeuvre is not relevant for the initial terrain consideration in the event that OEI actually prevails ? No reason why the OEM can't schedule more than minimal data but someone has to pony up the ante to obtain it ..
some places .. require a bank angle of 20° and a maximum speed of 158 kts during the early Left turn - and terrain is definitely a concern.
Providing the regulatory approval is obtainable and the weight penalty can be tolerated, that's fine. If turn radius is critical one sometimes is constrained with available options.
.. not all of them do it the same way, especially when it comes to adding a turn into the mix.
True .. but, for critical runways, generally the options may dictate a very similar strategy.
Each aircaft has its own quirks and limitations.
Waffle. The numbers will vary a little but a twin is a twin and goes like a twin at commercial weights .. triples and quads in a similar vein.
.. the real voodoo in the mix, the winds.
If one fails to take account of boundary consideration winds for the escape ... turns or no turns ... one is foolish
There is no public criteria that defines how to do this, nor sets any parameters for each of the variables.
Nonsense. The AFM provides plenty of guidance in the way of examples or other OEM data is available to achieve the same end. In any case, even the most bog rat of ops engineers can do the basics just fine.
I am not going to tell you how to get there, you told me you could do it.
The operator should have scheduled appropriate data in the way of RTOW charts or similar. If a SID is not achievable OEI then the operator should have scheduled an alternative procedure. There ought to be nothing in the way of hit and miss with weights and tracking intentions.
If there is a turn, there is a containment area associated with that, bank limiting and turn radius keep you in the containment area.
Cart before the horse. The terrain analysis defines the required track details. That defines turn details. Required radius defines speed and, to a small extent, bank angle variation.
EO is an emergency, and is treated as such in the criteria.
Nonsense. EVERY takeoff is predicated on OEI for a heavy aircraft. The fact that the great majority of departures don't see a failure is a benefit to the crew's sweat index .. but the bean counters don't get any credit for that fact in regard to RTOW.
Just becuase there is an EO SID, doesnt mean you can use it.
Depends on what the operator has scheduled ..
[The ACI link doesn't appear to function .. perhaps you can revisit ?]
There are known impacts to departure payload due to obstacles in departure area
That's quite profound ..
