BAC Test Performance Test Flights

[PaulC]

Hello All,

For my own amusement (and because I'm of the odd breed that like flight planning and all that jazz before flying) I'm going to embark upon a series of test flights for the 1-11.

Things I've noted so far that I want to test and produce figures for are;

Climb to altitude tables of distance/time/fuel use
Cruise Consumption at FL200, 250, 300 and 340
Descent distance/time/fuel use

I'll do these at 50, 75 and 100% weights.

If anybody else likes this sort of info and can think of anything else that would be handy I'll gladly do it, although I suspect I'm alone in this!!

I used to have the BAC flight planning manual knocking around somewhere with all those tables in it. Must have got lost in a move sometime First flight I planned with them was Luton-Bologna and I was 18lbs out on the burn-off!!

Funnily enough, that's what the chief pilot said when he called me into his office!! Told me I was a mile off with the fuel, I dashed back to my desk, looked at my notes and went back and said I can't have been, which is when he dropped the '18lbs' on me. Mediterranean Express/G-AZUK 1987

What a swine!

I don't know why I do it to myself as I'm always out on my fuel!

Back in the time of the 1-11, what was the fuel reserve/contingency requirement or have they been as they are now for a very long time?

It would be the standard CAP360 fuel requirements back then. Min landing fuel was 2000kg.

[PaulC]

Ah, thank you: that's much easier!!

I'm fascinated to know how you can get accurate to 18 lb, surely the gauges aren't that accurate

I suspect either that someone was having a joke with Nigel as a new boy ( of the sky hooks, or verbal agreement forms variety ) , or that there is a decimal point error somewhere. 18 lbs was about 12 seconds burn in the cruise in a 1-11
