If in doubt, ASK
Hi,
good answers all round. Watched a crew in a simulator conduct the same departure 5 times in a session, following the Co EOSID procedure. The SID required a turn at Rwy head/50' through approximately 210 degrees. The clean up altitude was 800'. Crew on each effort reached 800' and commenced cleanup, having rigorously set bank angle limit to 15 degrees. All occasions resulted in the sim flying over high terrain with a Mode IV warning followed by Mode II hard warnings, on top of EGPWS advisories. Sim was ngt VFR conditions, great view of the antennas on top of the hills passing by about 30' below the sim.
Procedure took about 2 years to change to ensure clean up was not accomplished until turn complete, (and above 800').
On the majority of engines, if the customer will pay for it, the manufacturer will change the limit time from 5 minutes to 10 minutes. There may be exceptions....
A further EOSID had the crews using a DME that was not the one used for the SID, not uncommon. The EOSID used to be briefed routinely on the wrong DME which was also tuned, and would have the crews flying straight into a fairly substantial (and non frangible) mountain range, rather than turning to avoid it.
Oddly, on occasions, the problem is greater with low weights and improved performance, as the early acceleration may occur before a safe heading has been achieved. YBCS used to be like that off Rwy 15.
If in doubt, or the procedure appears odd, I strongly suggest you ask, the life you save may be your own.... Do note that unless you are operating under JAR/EU OPS, there is no requirement to liase with the authorities at any airport about your EOSID procedures, and so the procedure that runs you straight through the middle of an adjacent airport may be a bit of a surprise to all. (JAR/EU OPS requires a response from each NAA you operate to/from to accept the procedure you have employed. Haven't found any other NAA that does).
stay safe.
