i need to know the take off speed for the avro lancaster and how much runway it eats up during take off my freind says it takes 2000 feet with a dambuster bomb but i dont belive him any help would be nice thanks guys[:D]
I have the information you require. Unfortunately its downstairs and I need help to get down the stairs!!. So watch this space. should have it for you tonight my time.
TTFN Dai.
The Lanc would, with all four Merlins at full song, lift the tail at around 50 knots. At 90 knots the pilot would hope to be getting airbourne, climb out would be at 140 knots. As for the length of runway required i’m not sure, but like the quoted airspeeds above i’m sure it would be variable depending on windspeed, power available and all up weight. I have read more than one account of aircraft going through perimeter fence when they should have in the air!! Sav.
[?]You did’nt mention wether you reckon your friend is too short or too long in his estimation, from what i can find 4650 feet( .88 mile / 1.4 km - 64 feet in 1:72 ! ) is the full run and has a Lanc 50 ft off the ground, (tho i dont know with what load that figure is based on)The ‘up-keep’ bouncing bomb was fairly light at 9,250 lb (4195 kg) and only ever used on that night .
Heavy single load 12,000 lb tallboys or 22,000 lb grand slams required ‘specials’ which were lightened by having one or two of the three gun turrets removed. 617 Sqd apparently had problems at Losimouth with runway length and fitted more powerful merlins to cope
Maybe Dai can back -up our posts when he gets back to you,
and settle the questions
Back from the other end of the house. According to the information at hand, Famous bombers of WW2 by William Green and Cockpit plus a monograph on the Lanc. there is no reason why it could not get off in 2000ft with the weight of a dams bomb onboard. Mind you it would depend on fuel load, wind and the pilots ability. That said the Lancaster and Halifax could get of the ground in a far shorter distance (with a heavier allup weight) than the B17. So yes she could.

thanks but i geuss i have to admit im wrong ( i hate that) to my bud thanks for the info and what would you say about somthing like a p 51b mustang how much runway would it eat up for a take off???
