Your distance from A-B is 50NM
Your distance from B-C is 40NM
it takes you 30 minutes to arrive at way point B and you arrive at 12:35
What time do expect it to arrive at waypoint C assuming W/V stays consistent
This question has been flagged as being in an exam by multiple students, give it more attention
A
13:02
B
13:09
C
12:59
D
12:52
Explanation
It took us 30 minutes to cover 50 NM, this means our ground speed is 100 Kts
To do the remaining 40NM can now be calculated
Time to do 40nm = Distance/Speed
40/100 = 0.4
0.4 X 60 = 24Mins
Add 24 Mins to 12:35 = 12:59

You are flying at 1000 ft.
What rate of climb is required to reach 5000 ft in 20 nm if your ground speed is 125 kts?
This question has been flagged as being in an exam by multiple students, give it more attention
A
Approx 200 ft min
B
Approx 500 ft min
C
Approx 410 ft min
D
Approx 350 ft min
Explanation
Lets work out how much time we have travelling at 125 kts , how fast will we cover these 20NM
Speed=distance/time
Time = distance/speed
Time = 20/125
Time = 0.16
Time in mins = 0.16X60 =9.6 Minutes
so we have 9.6 Minutes to climb 4000 feet
4000/9.6 = 416 ft/min

Your current position is 48°58.1' S. Assuming you stay on the same meridian of longitude and fly due north for 93 nm, what will your new latitude be?
This question has been flagged as being in an exam by multiple students, give it more attention
A
47°25.1' S
B
50°33.1' S
C
50°30.1' S
D
48°55.5' S
Explanation
48°58.1' S ... we fly north for 93NM , so what will our new latitude be?
remember we are in the southern hemisphere already
48°58.1' S - 93...
When we get to 48°00'1S we will of travell 58NM with 35NM remaining as each minute of arc = 1nm
lets go another 35NM north from there and we get to 47°25'1

At 12:30 your DME from a station reads 20 DME, at 12:45 your DME reads 40 DME
Assuming you are moving directly away from the station, how fast are you travelling
This question has been flagged as being in an exam by multiple students, give it more attention
A
60Kts
B
80Kts
C
40Kts
D
100Kts
Explanation
This is mental maths if you think about it
In 15 minutes we have travelled 20NM
So in 1 hour we will of travelled 80NM which gives us our ground speed of 80Kts

What rate of descent is required to descend from 6000 ft to 2000 ft in 15 nm if your ground speed is 80 kts?
This question has been flagged as being in an exam by multiple students, give it more attention
A
Approx 250ft /Min
B
Approx 300ft /Min
C
Approx 720ft /Min
D
Approx 360ft /Min
Explanation
First lets calculate how long 15nm will take us at 80Kts GS
Speed = distance/time
time = distance/speed
15/80 = 0.1875
Change to minutes 0.1875 X 60 = 11.25 Minutes
So we have 11 minutes to descend 4000ft
4000 /11 = 363feet per min

Over a period of 9 minutes, our aircraft uses 4 litres of fuel
We have 109 litres of fuel remaining, what is our endurance (to tanks dry)
This question has been flagged as being in an exam by multiple students, give it more attention
A
2.5 Hours
B
6 Hours
C
3 Hours
D
4 Hours
Explanation
Maths question
We do 4/9 X 60 to give us our hourly usage of 26.6 Litres per hour
Then we have 109 litres of fuel in our tank, / 26.6 Litres per hour of fuel burn = 4.09 Hours of fuel, thus 4 hours is our closest answer
