From the ground up workbook

[redwing]

Just wondering for anyone who has the FGU workbook, on page 67, how did they calculate fuel burn enroute, and come up with a number of 0.4 under the "Fuel Calculation" heading?

[Tim]

wanna post the question from the book?

Here we go. I'm assuming OP is referring to question 1

EDIT: The answers are first then the question.

[AUGER9]

Did they give you a fuel, distance, time to climb chart? In that segment, they're referring to the takeoff and fly to your SHP only. By the the time you level off at altitude, you likely only have a very short distance to go before you reach your SHP, in this case the VOR.

Yes they did get that chart, but I am confused on how they got the 0.4 under fuel enroute to set heading point

and thanks flyingdan for posting a copy of the question

[flyingdan]

No problem.


I didn't see the fuel, time and distance to climb in the workbook.

Just looking at the question I would assume that you only have a very short distance to go "en-route" to the destination point so that's why you only use 0.4 just like AUGER9 mentioned.

[AUGER9]

What you want to do is measure the distance from the airport to the VOR. Then, determine with the chart, how many miles you cover while climbing up to 4500'. The difference between these is your "enroute" distance from the airport to the VOR. Use that distance to determine how long and how much fuel you use after levelling off.

[flyingdan]

Keep in mind though that usually the GPH numbers given are reflective of an engine "leaned as per manufacturer's instructions." At least in real life. In the workbook it may be different.

What's the climb distance from 300' to 4500'?

With that, I'll tell you what I got.
