1 . Locate V1, V2, VR (see Figure on the lookout for. 19).

Temperature is standard. Reference Stand 2 . one particular Standard Temperatures at 5K ft is definitely 5 deg C. On the other hand, using the guideline of 2 deg C for each 1000 ft sea level gives all of us 15 degrees C; therefore , at 5000 ft the temperature is 10 degrees less or 5 degrees C. Pertaining to Density Arete Adjustment, make use of Column N.

Flaps-5 Weight 300K yields:

V1= 136 KIAS

A HUGE SELECTION OF = 148 KIAS

VR = 141 KIAS

installment payments on your For a new weight of 350, 000 lb and using Desk 7. two: Summary of Useful Takeoff Proportions in Modern Aircraft Transportation Performance, find the subsequent: a) Takeoff Ground Rotate with excess weight increased to 350, 500 lb.
