EDTO vs ETOPS
A new term that I came across recently
EDTO Extended Diversion Time Operation Is it the same as ETOPS.... whats the difference is there if any actually. In terms of applying of the rule JAA and FAA do have a separate document for EDTO but it refers to guidelines in the ETOPS for actual certification... |
Subtle differences. EDTO is less restrictive on a practical level, usually to accommodate geographical circumstances. We use 180 minute EDTO here in Pacific region.
However as we all know, the passengers will not remain seated after a ditching whilst we prepare the rafts. Chaos will ensue for sure. The regulators will have to answer questions when this does happen, which it will one day. |
B747/A380/DC8/A340 etc not affected by ETOPS as not 'T'....
Their equivalent maybe?? :confused: |
ETOPS is now applied to all.
CFR 121.161 refers. ETOPS now just means ExTended OPerationS. |
The EDTO approval process for large aeroplanes is valid for regular public transport (RPT) or charter operations which include certain cargo operations. To be eligible for EDTO, the specified airframe/engine combination must have been certificated to the airworthiness standards of Transport Category aeroplanes Federal Aviation Regulation (FAR) Part 25, the European Aviation Safety Agency (EASA) CS25 or the equivalent.
Three levels of operational approval are used for two- engine aeroplanes:
Note: In the case of all EDTO beyond 180 minutes, additional flight dispatch requirements apply. System redundancy levels appropriate to EDTOs must be reflected in the Master Minimum Equipment List (MMEL). An operator's MEL may be more restrictive than the MMEL considering the kind of EDTO proposed and equipment and service problems unique to the operator. EDTO alternates serve a different purpose than the destination alternate aerodrome, and would normally be used only in the event of an engine failure or some other aeroplane system failure, an aerodrome must not be listed as an EDTO alternate unless the requirements are met. The procedures established by the operator must ensure that EDTO is limited to flight plan routes where the approved maximum diversion time to EDTO alternates can be met under standard conditions in still air. Operators must provide for:

Depends who's rules you operate under.
ETOPS in EASA is not the same as ETOPS in the states or EDTO for the Aussies. in EU land ETOPS is for twins. |
1) EDTO applies to all aircraft. ETOPS twins only
2) EDTO less restrictive for the operator. (Not as generous as ETOPS eg weather window duration, min FFS required) In short |
