Hi Stuart,
I have a query on P20 of eText CPL/PPL nav.
In the Safe Endurance tabulation (P20) a Fixed Reserve is required.
The nominated amount is 45mins @ holding fuel flow of 27lph
and the amount entered being 29.25L rounded to 29.00L.
At 45mins holding shouldn't the amount for Fixed Reserve be 20.25L rounded to say
20.00L not 29.25L?
60 mins = 27L burn rate so 45 mins = 20.25 burn rate, rounded to ??
Is it a "typo" or am I completely missing something along the way?
I can't get to your answer the way I am allowing for the Fixed Reserve amount.
