but in a country that uses U.S. TERPS
Not overly familiar with TERPS and would defer to you on PANS/OPS as well, in any case, good sir.
AEO planned turns are not commonplace but, sometimes - due to terrain - are necessary.
For instance, Hobart 30 (AUS) has an early turn to avoid tiger country. It used to be SOP to do this for all 30 departures as the OEI escape followed this procedure. I imagine the present operators still do the same as the payload penalties running straight out would be uneconomic ..

Hello,
The way we do it at Air Macau: We take off, we disregard the lateral guidance of the FD initially: As we cross 200 feet AGL, we start turning (max bank 15°) then at 400 feet we follow the FD to comply with the RNAV SID.
Some captains even climb to 400 feet first before starting the turn. Never heard a complain about that.. And there is no obstacle to worry about... Anyway unless you are heavy on a hot day, you are generally above 400'' before the DER, at least on A 320s.
Just for interest, according to our SOP we are not allowed to turn below 200 feet AGL and between 200 feet and 400 feet AGL, max 15° bank then 30° above 400 feet AGL.

To keep the splay inside of Mt Lord and the terrain there the V2 needs to be kept below about 155KTAS.
Back to the thread, if turns were not allowed below 400', then OEI most aircraft would have to go straight for quite some distance! On paper at least

Thread drift but I know at least one major operator runs straight out even in their OEI procedure. The pitt water departure requires VMC to 1000' but all the other SIDs remain on R-300.
