Landing Speed For Boeing 707 ???

Question

Can someone please tell me the AVERAGE landing, approach and take off speed for a boeing 777 please, i know it's different with weight and fuel etc.. but roughly please! Thanks... OR just the landing speed will do if you don't know thanks

Answer 1

a 777 with full flaps will touch down at a final approach speed of 142 to 158 knots. (average) which will be 163.411 mph to 181.824 mph.



approach is to be done average 180-200 knots (207.141 mph-230.156mph)



takeoff rotation speed depending on weight is around 155-170 knots with flaps 20 (178.371mph-195.633mph)



PS: if your question it says 707. in your details it says 777, i answered about the 777. (because i don't know the 707's)

Answer 3

Look in an old Instrument Flying Handbook. Near page 170 there is a table of speeds.

Answer 4

19000 lbs/f

max/min TOW

335000/146000

10840 ft MRTOW

==============================

FULLY LOADED

==============================

a=(32.17)*335000/(19000*4) = 7.29 ft/s^2

d=1/2*a*t^2

5420=1/2*7.29*t^2

5420=3.645*t^2

5420/3.645=1486

38.56 secs TOT

----------------------------

Vf=7.29*38.56

Vf=281.11 ft/s

Vf=192.54 mph Takeoff Speed

Answer 5

I believe it's around 140 mph

Answer 6

I'm gonna guess something ~180mph.
