Hi out there. I read a lot in this forum about fuel planning in SD. Even the pros and cons of making a whole new fuel calculation each stop I plan (with the "land here" function) vs. calculating with the remaining fuel.

BTW, I also plead for a fuel calculation possibility for the whole trip. With calclulate on base of remaining fuel (if you need more votes for that )!

But I found so far no answer for a mostly common problem we have (expect of "do it manually"):

- I recently plan a trip of about 2 hours flight time. That is absolutely within my tank capacity WHITOUT any refuelling including reserves.

- The trip has four stops (or more. But even with one stop the problem exists)

- At each leg I get a fuel calculation by SD including the 30 min. holding.

This makes about 120 minutes of holdings/reserve on a 120 minute flight with 4 stops. That does really not make sense!

Altough I do understand why you (until now ) decided not to implement a feature that calculates the fuel based on the remaining amout after first landing, I cannot find a way to tell SD "please use the 30 Min. Holding and contingency JUST ONCE".

It is absolutely clear that I can plan a flight without "land here" and ad manually the amount of fuel for landing and departure/take off. But that is IMHO much more critical and error-prone, than computing with the reamining fuel I think. 

A suggestion for that often discussed topic could be: In the settings offer a checkbox which says "Plan or do not plan reserve/holding/contingency after each landing". If you want add "we highly recommend to leave this active". Or an explanation "If you turn this to off reserve/holding/contingency fuel will be calculates just once for the whole trip".

But the - in my opinion -  best solution is the here in the forum often suggested way to calculate a multiple stop (or sector) with the remaining fuel and send a warning when there is not enough fuel for further legs.

Thank for your suggestions on my question above, hints and answers

I think you may be asking for far too much added complexity to simple fuel planning.

I too fly an aircraft with only a single 49 litre fuel tank. I know my fuel consumption, averaged over many hours of flying, to be around 16.5 litre/s per hour.

I feel comfortable knowing a single flight of, say, 2hrs duration will leave me with about 45 - 55 mins reserve before only fumes left in tank.

Taking into account that some fuel will be unusable I will start to feel uncomfortable about flying for longer that 2 hrs 15 mins.

So, I know not to fly for more than 2 hrs 15 mins thereby giving me around 30 mins maximum reserve, assuming my fuel tank was completely full.

I also carry with me a calibrated dip stick so I know exactly how much fuel I have left in my tank...

Sometimes it is best to go back to basic, manual, flight planning for some safety critical elements, such as fuel planning.
