Morning Rotorspeed;
SS - Your response concerns me - you say I got my facts wrong. (a) You say the red low fuel light comes on at 48kg remaining. The manufacturer says 60kg, according to Airbus Helicopters' information as posted earlier. (b) They also say then you must land in 8-10 minutes. Given that, I would take the lesser time of 8 minutes as the limit, but I'm surprised you want to take the longer end of the at 10 minutes. Maybe I have misunderstood something, but perhaps you could review these "facts" and set out what they really are?
my brackets


(a)
Lets have a look at the facts for the this one, which was in reference to your posting, "You also know your red low fuel warning light has not yet come on, which it should at 60kg,"

ref: http://www.airbushelicopters.com/sit...18-Rev0-EN.pdf

"LOW FUEL 1 Illuminated - 26 - 34 kgs
LOW FUEL 2 Illuminated - 22 - 30 kgs "

(The serviceable range is 48 - 64 kgs)

Therefore at 48 kgs, both Red Warnings should be on, not as you say at 60 kgs.

(b)
This is in reference to your posting, "when the book says you must land within another 8 minutes."

LOW FUEL 1 and/or LOW FUEL 2
"LAND WITHIN 10 MINUTES" (a committed to memory item)

Therefore when the light(s) come on you must land within 10 minutes, not 8.
It does not say 8-10 minutes, it says 10. You are mixing up different types



Anyway, it seems that you have agreed that you would not actually land when you had just 70kg in my example, which was the original point.
No I haven't. I gave you my example.
Given the choice between landing 10 kgs below 70 kgs in order to get to Blackpool airport, having to write a report and explain what happened … and ditching... I think I'd take the former ….. wouldn't you?
