Hi Bob. I believe the answer on page 130 for question 5 of the PNR question set is 109 gallons however the answer says A (104). Is this an error? Also can you please explain why is shows 17.25 for reserves when the data says it’s 17? It’s a small thing but I know the answer would change quite a bit with the difference

Thanks

G'day
You must have an older copy as that answer has been updated to the new fuel requirements and appears correct



as for not rounding it's not going to make that much difference

Thanks Stuart.

My next question relates to page 244 question 7 of the CPL practise exam 1.

Instead of going through the whole beatle diagram and working out trip fuel etc, is it possible and legitimate to start with 2360 and then minus the weights to find the remaining payload allowed? Is it necessary to go through all the steps even though we know the MZFW is 2630 anyway?

Cheers

Hi guys

I have an issue with this answer but not the same one as above..

Shouldn't we be calculating the fixed reserve of the holding fuel rate as per the CAAP?

"The amount of fuel, expressed as a period of time, for a helicopter conducting
an IFR flight, an aeroplane or an airship, required to fly at holding speed at
1,500 feet above aerodrome elevation at ISA conditions,"

Everything else I have come across calculates fixed reserve at holding rate. Any reason why with this question we are asked to calculate it at cruise rate?

The CAAP is 'advice' not 'law'. If a particular question says that your company chooses to calculate the fixed reserve at cruise rate then that's what needs to be done. On the other hand, if the question says that your company chooses to comply with the CAAP, then you would calculate the fixed reserve according to the CAAP.
