ATC tells you to intercept the 270° radial at a 60° angle. What do you do?
- Turn to 270°
- Check your ADF. We’ll say its to the left of 000°
- 270-60=210
- Turn to 210°
- Once you ADF needle hits 060°, turn on to 270° (HI) and your ADF should down 000°
What peice of information do you need to figure out what heading you need in order to intercept a radial at a certain angle?
You need to know whether the ADF needle is pointing to the left or right, which will tell you if you need to add or sub the intercept angle from the intercept radial angle.
To get this turn the AC to the parallel track and see where the ADF needle is
If the question asks what the ADF will read at the moment you intercept a radial but before you turn on to it…what do you need to figure this out?
Assume an angle of intercept of 30°.
If you are intercepting an inbound radial, it will point to either 330 or 030
Outbound will be either 210 or 150
….I think.
If flying inbound to an NDB the ADF pointer will be pointing towards the ____ of the AC. If outbound it will be _____
Inbound: Pointing off the nose at 360°
Outbound: Pointing off the tail at 180°
If you have just overflown an NDB what intercept angle should you use to track outbound on any of its radials?
15°
“Flying towards an NDB on a bearing of 215°” is giving you what information?
BTS (Bearing to the station). I can get the BFS with this by subtracting 180. BFS is 035°
What is important to know about this kind of question?
- Fly to the station first and after you have passed it, then intercept the 123 radial at 15° (15 degrees is only used when very close to the station and tracking outbound from it)
- It has given you the BTS, which allows you to find the BFS
What is your BFS (bearing from station) in this question?
123°
RB would be 360°
How do you get RB if they only give you your MH and BTS?
BTS - MH = RB
Example:
MH: 305
BTS: 250
250 - 305 = -55 + 360 = 305 RB
