BAC Test Performance Test Flights

Hello All, :hello:

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!! :agree:

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 :wall: 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

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

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.

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

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
