Fuel Flight Planning

Chris Trott · Post by **Chris Trott** » 05 Jun 2006, 02:09

Okay, made a 3+ hour flight. I have thus revised the fuel planning due to some new numbers at a hotter temperature.

1st Hour - 3000 KG/HR
Subsequent Hour - 2000 KG/HR
Reserve/Alternate - 4500 KG (1 missed approach, 45 minutes reserve, 30 minutes to alternate)

Thus, a 1 hour flight requires a start-up FOB (fuel onboard) of 7500KG.

Heathrow - Helsinki took 7000 KG and I took off with 9000 KG, so I was on absolute minimums (only had the 45 min reserve left).

Aircraft - HS.65 Argosy

First Hour - 8000 lbs (3630 kg)
Subsequent Hour - 4000 lbs (1815 kg)
Alternate - 2000 lbs (910 kg)
Reserve - 5000 lbs (2270 kg)

Normal arrival - 7000 lbs (3175 kg)

Suggested minimum dispatch (1 hour flight + reserves + alternate) - 15000 lbs (6805 kg)

Based off of 2.8 hour flight from East Midlands to Milan.

Hi Guys

Don't forget to mention what aircraft you are talking about.

Oops. Fixed.

hehe Chris, you need a double fix. Helsinki?

Yes, Helsinki. That's Vantaa, which is where I went in the Merchanman.

Note on the "Arrivals" list CBF904F, the flight I flew. Are you telling me John that you don't know your own flight routes?

When we had 2 routes, if I thought about it long and hard enough I could remember most of the time. Now we have nearly 1600 it takes a bit longer and harder to remember

I know that this is likely to be a really stupid question but I just did my first flight in a Super VC10 from Heathrow to Rome and I duly followed the VC10 fuel planning advice in Dan's post above, working out I needed somewhere around 30 tonnes for the flight...

Except these tonnes aren't the same ones I use clearly as I ended up with over 20,000 kg of fuel in the tanks on landing and a huge loss for the VA (sorry John!) :redface:

Here goes the stupid bit... I thought a tonne was 1000 kg..?? :think:

I guess not :crying:

Can someone put me out of my misery please? (At least I won't need to fuel up for the return leg...)

Dom1, dont worry too much, you can make it up on the return flight since you already have 20000kg of fuel in the tanks.

I find the best way to estimate the fuel usage is to look though our history of past flights for someone else who has done a flight of simular distance with the same AC.

Be sure that when you fuel the airplane, you put in 30000 (no commas or periods) and that the little dot that is clicked is "kg" and not "lbs". That will ensure that the right amount of fuel is added. I don't know any other way for excess fuel to be added into the aircraft other than you somehow converted from kg to lbs and back to KG or something. The system is programmed in KG, so if you put in the KG you want, it's the KG you get. It's only when trying to fuel in LB that you get the occasional odd conversion, but it's never off by more than a couple hundred pounds.
