Hi all, I’m new here, so be gentle.
Ive got my aptitude testing (hopefully for AAAvn) in a few weeks, starting to ramp up the questions im working on as prep, but im making the required figure up and have trouble figuring out a decent and concise way to do them (pretty much essential seeing that I have a bit less than 1 min to do each in). Was hoping that I could enlist the help of you guys, many who have been around the block a few times already, in checking my answers and/or showing better/quicker ways of doing such calcs.
Many thanks
[edit] And yes i have used the search function, but found only questions relating to more basic calcs.
1. Aircraft A departs @ 1040 @ 240kts
Aircraft B departs @ 1240 @ 300kts
From same origin
How long does it take B to pass A and at what time?
Working: (working under d=st, and distance travelled have to be equal when B passes A)
480 (2hrs @ 240kts) + 240t = 300t
480 = 60t
t = 8hrs
therefore B passes A @ 2040 2400nm from orgin (long legs, I know)
2. Two AC (A and B) 800nm apart, both departing @ 0000
TAS A = 240kts
TAS B = 120kts
How far from As origin do they “meet” and how long does it take?
Dist(A) = 800 x 240 / 360 (120 + 240)
= 800 x 2/3
= 533nm
T = D/S
T = 533/240
=2 hrs and 14min
3. (these are the ones that im having trouble with)
2. Two AC (A and B) 800nm apart, A departs at 0000. B departs at 0035
TAS A = 240kts
TAS B = 120kts
How far from As origin do they “meet” and how long does it take?
Again, if you bothered this far, thanks
