Some help would be very appreciated with PNR endurance.
With the new CAAP. For PNR endurance calculation what do we use ?
TRIP FUEL = Endurance ?
Also Safe Endurance is TripFuel + Variable reserve ?
Please some clearification would really help thanks.
While on the subject of PNR and safe endurance, given the November 8 2018 CAAP 234-1(2) changes, is ALTERNATE FUEL included as TRIP FUEL for Safe Endurance now, but not subject to the 10% variable reserve (assuming RPT/Charter)?
I tried explaining to a friend and I hope the following is correct?
"so say you have 180 L total and your burn is 25 Lph, and you have an alternate that requires 20 L. You want to find safe endurance, so
180 L total
- 19 L Fixed reserve (45 mins)
- 5 L taxi/startup
- 20 L alternate fuel
= 136 L
Now you need to take away the variable reserve, so
136 L / 1.10%
= 124 L
BUT trip fuel for safe endurance includes any alternate fuel so,
124 L + 20 L alternate fuel
144 L @ 25 Lph = 345 minutes safe endurance"
Clarification on this post-fuel mayhem would be greatly appreciated
