IFR Navigation 7 - 1/60 Rule

An aircraft is flying on a heading of 075 and a track of 082. The aircraft is travelling 80kts. What is the drift?

• 7 degrees of left drift

• 7 degrees of right drift

• 5 degrees of right drift

• 5 degrees of left drift

Drift is:

• The angle between the aircraft heading and the track

• When the aircraft is being pushed by wind

• The magnetic angle between the heading of the aircraft and the track.

• None of the above

Drift angle is:

• The angle from the aircraft's heading to the track the aircraft is flying

• The angle at which the aircraft is being pushed off track

• Track minus the relative bearing

• None of the above

An aircraft is flying from NZCH to NZTU with a TAS of 122kts and a tailwind component of 23kts. What is the groundspeed?

• 99kts

• 155kts

• 145tks

• 100kts

You forgot to correct your heading for the wind on the way to Kaikoura. After travelling 30nm you have a track error or 4 degrees. How far off track are you?

• 5.2nm

• 52nm

• 2nm

• 20nm

After travelling 50nm you realise you are 10nm off track. What is your track error?

If your track error is 3° to the right of track and your closing angle is 7°. What way must you turn and how many degrees to get back on track? (total corrrection)

• 10° to the left

• 10° to the right

• 4° to the left

• 4° to the right

You are travelling from A to B. After 40nm you are 5° off track to the left. What is the total correction needed to regain track?

• 5° to the right

• 7.2° to the right

• 5° to the left

• 7.2° to the left

You are travelling from A to B. After travelling 70nm you are 3.5nm off track to the left. What is the total correction required to regain track?

• 3.5° to the left

• 3.5° to the right

• 6.5° to the right

• 6.5° to the left

You are on the NZCH 13DME arc. Currently on radial 235. If you were to continue on the arc, how many nm do you need to travel to reach the 200 radial?
