Fuel Planning Questions

Hello, I have a big interest in flight planning and trying to replicate real procedures as accuratly as possible in my hobby. Mostly interested in EASA regulations. First question: I'm wondering if altitude restrictions for SIDs and STARs need to be/are followed while flight planning, or if continuo...

Re: Crew Rest Question

I'll rephrase as I understand the wording in my previous post could be misinterpreted. I'm mainly interested in if an entire row (on one side of the aisle) is curtained off to allow several crewmembers to rest at the same time, or if it's just because you can't have passengers in the seats next to t...

Re: Crew Rest Question

The rules vary per jurisdiction. This is for my operator. - Pilots may use a business class seat for rest. However. time spent resting in a seat counts less than in a bunk. That is, an hour spent resting in a seat gives you less duty time extension than an hour in the bunk. - Cabin crew may also re...

Crew Rest Question

Hello! I hope this is the correct forum for this question. I've been looking into how crew rest works for single aisle long haul services (like the A319LRs, 737 BBJs, A321LRs, and future A321XLR) and have a two questions. Quick note: I'm interested in EASA rules. There are some pictures online of (u...

Understanding Emergency Descent Altitudes

Hello, I'm trying to understand how altitudes are corrected during emergency descents where obstacles are present, and temperature and QNH is below ISA. I've been looking at an emergency descent profile from an Airbus FCOM that gives a total of 2.5 min until FL290 needs to be reached, 7 min until FL...

Re: Iraq Overflights

The company I work for has some overflights of that region. I didn’t operate these routes yet personally, but our last simulator session had a LOFT scenario that - at least in my session - led to a diversion to Erbil. As the terrain in that region is quite high and possibly limiting for the depress...

Re: Iraq Overflights

I wouldn't say that NOTAMS can be disregarded, but of course, if you have a "Jesus Christ Emergency", you do what you need to get safely on the ground. If you have a decompression or a drift down, you certainly won't be able to maintain FL320 or higher. It's just a risk you take I suppose...

On Safeairspace , most NOTAMS/AICs seem to recommend to stay above FL320 and only operate on UM860, UM688 and UL602 [......

Both have to be analyzed, but not together - TDP is normally fix...

Re: ETOPS over Greenland

Sounds like a pilot who does not understand their own fuel policy, this is a terrain critical point, not a EDTO critical point. Terrain critical points are about the strategy to get down to a safe level and then where to proceed depressurised. I'm not sure I understand this assumption, the pilot st...

Re: Fuel Policy and Route to Destination Alternate

Contingency fuel is considered to have been burnt, however buildups like for ETDO critical points are considered as being extra fuel available at the destination once past the critical point. For example if the critical point required an additional 30 minutes of fuel, that 30 minutes of fuel would ...

Re: Fuel Policy and Route to Destination Alternate

It seems it is not so easy for the flight planning systems to perform this calculation automatically, as the missed approach procedures usually don't guide you into the airway structure like a SID. Therefore we have an approved method, where the system plans the expeted route between destination an...

They would include the full route to the alternate, where you have assumed they are getting a direct to the initial waypoint I think you will find that will match a waypoint in the missed approach, ie the termination waypoint for the missed approach would be a start waypoint for the route.
