An aircraft is flying TAS 180 knots and tracking 090°T. The W/V is 045/50. How far can the aircraft fly out from its base and return within 1 hour?
Formula:
EOH / O+H
E = endurance which is 1hr
O = groundspeed out
H = groundspeed home
You need to work out the ground speed using your whiz wheel or CRP
Add it to the formula just to be on the safe side I would do E x O x H then press equals
Add O + H then divide first figure by second figure to avoid any calculator errors, good luck!!
An aircraft at FL330 is rerquired to commence descent when 65 NM from a VOR and to cross the VOR at FL100. The mean GS during the descent is 330 kt. What is the minimum rate of descent required?
Height to loose
____________
distance / speed x 60
height to loose = 330 - 100 = 23,000ft
distance is 65nm
Speed is 330kt
so,
23,000
--------
65 / 330 x 60
Answer is 1946ft/min
