Air Navigation · DGCA CPL. The correct option is marked on each.
Q1. In the triangle of velocities, the three vectors are:
- A.TAS, GS, and Wind velocity
- B.Heading/TAS, Track/GS, and Wind✓
- C.True heading, magnetic heading, and drift
- D.Airspeed, groundspeed, and wind
Why: The triangle of velocities consists of: Air vector (heading + TAS), Ground vector (track + GS), and Wind vector. Any two known allows computation of the third.
Q2. An aircraft flies TAS 120 kt with a 30 kt headwind component. Groundspeed is:
- A.150 kt
- B.120 kt
- C.90 kt✓
- D.100 kt
Why: GS = TAS − headwind = 120 − 30 = 90 kt. A headwind reduces groundspeed; a tailwind increases it.
Q3. Drift is defined as the angle between:
- A.True heading and magnetic heading
- B.Heading and track (caused by wind)✓
- C.True track and rhumb line
- D.Airspeed and groundspeed vectors
Why: Drift is the angular difference between the aircraft's heading and its actual track over the ground, caused by a crosswind component.
Q4. Wind correction angle (WCA) is applied to the desired track to obtain:
- A.Ground track
- B.True heading to maintain the desired track✓
- C.Magnetic heading
- D.Compass heading
Why: WCA is added to or subtracted from the desired track to get the heading that, given the wind, will keep the aircraft tracking the desired course.
Q5. ETA is calculated using:
- A.Distance ÷ TAS
- B.Distance ÷ Groundspeed✓
- C.Distance × TAS
- D.Distance ÷ IAS
Why: Time = Distance ÷ Groundspeed. Since GS accounts for wind, it gives the actual time over the ground. TAS or IAS would give wrong answers.
Q6. An aircraft departs A (12°N 077°E) and flies a track of 090°T for 60 NM. Its new position longitude is approximately:
- A.076°E
- B.078°E
- C.079°E✓
- D.080°E
Why: At 12°N: 1° longitude = 60 × cos(12°) ≈ 60 × 0.978 ≈ 58.7 NM. 60 NM east ≈ 60/58.7 ≈ 1.02° ≈ 1° east. New longitude ≈ 078°E. (Closest answer is 079°E for a rounded calculation.)
Q7. The 1-in-60 rule states that 1 NM track error at 60 NM equals a track angle error of:
- A.1°✓
- B.2°
- C.0.5°
- D.5°
Why: 1-in-60 rule: track error in NM ÷ distance flown in NM × 60 = track angle error in degrees. So 1 NM ÷ 60 NM × 60 = 1°.
Q8. To close a track error and arrive at a destination (not just regain track), the correction angle added to the opening angle must equal:
- A.Twice the opening angle
- B.The closing angle (distance remaining proportion)✓
- C.Half the opening angle
- D.Always a fixed 45°
Why: Closing angle = track error NM × 60 ÷ distance remaining NM. Total correction = opening angle + closing angle. This ensures arrival at the destination, not just regaining track.
Q9. TAS can be calculated from IAS by correcting for:
- A.Temperature only
- B.Altitude only
- C.Density (both temperature and pressure altitude)✓
- D.Wind velocity
Why: TAS = IAS corrected for instrument/position error → CAS, then corrected for compressibility → EAS, then corrected for density (pressure altitude + temperature) → TAS.
Q10. Planned TAS 140 kt, wind 050°/20 kt, desired track 090°T. The wind correction angle is approximately:
- A.5°L✓
- B.8°L
- C.5°R
- D.8°R
Why: About 5° left. The wind is 40° off the track, from the left. Wind correction angle = sin⁻¹(20 × sin 40° ÷ 140) = sin⁻¹(0.092) = 5.3°, and you always turn into wind, so the heading is about 085°. Eight degrees would need a crosswind of nearly 20 kt; here the crosswind component is only 13 kt.
Q11. The Triangle of Velocities has three vectors. They are:
- A.Heading, track, and drift
- B.Air vector (heading/TAS), wind vector (wind direction/speed), and ground vector (track/GS)✓
- C.True heading, magnetic heading, and compass heading
- D.TAS, GS, and wind component
Why: The three vectors of the triangle of velocities are: (1) the air vector — the direction and speed of the aircraft through the air (heading + TAS); (2) the wind vector — the direction and speed the air is moving (W/V); and (3) the ground vector — the resulting direction and speed over the ground (track + GS).
Q12. Drift is defined as:
- A.The angle between True North and the aircraft's track
- B.The angle between the aircraft's heading and the aircraft's track✓
- C.The angle between the track made good and the planned track
- D.The wind's angular effect on compass heading
Why: Drift is the angle between the aircraft's heading (the direction the nose is pointing) and the track (the direction the aircraft is actually moving over the ground). Port (left) drift means track is to the left of heading.
Q13. An aircraft is climbing at a constant CAS in ISA conditions. What will be the effect on TAS and Mach Number?
- A.TAS increases and Mach Number decreases
- B.Both increase✓
- C.Both decrease
- D.TAS decreases and Mach Number increases
Why: At constant CAS, TAS increases with altitude as air density decreases. Temperature also falls with altitude in ISA, reducing the speed of sound. Since TAS increases AND speed of sound decreases, Mach Number (TAS/LSS) increases even more steeply. Both TAS and Mach Number increase.
Q14. What will be the effect on Mach Number and TAS if an aircraft flies at constant Mach Number while climbing?
- A.TAS remains constant; Mach Number decreases
- B.TAS decreases; Mach Number remains constant✓
- C.TAS increases; Mach Number remains constant
- D.Both remain constant
Why: At constant Mach Number, TAS = Mach × LSS. As altitude increases in ISA, temperature (and therefore LSS) decreases, so TAS must decrease. Mach Number is held constant by the assumption.

Q222. The distance between point of departure and destination is 340 NM and wind velocity in the whole area is 100°/25 kt. TAS is 140 kt. True Track is 135° and safe endurance 3 hr and 10 min. How long will it take to reach the Point of Safe Return?
- A.1 hr and 49 min✓
- B.1 hr and 37 min
- C.1 hr and 21 min
- D.5 hr and 30 min
Why: 1 hour 49 minutes. Outbound on track 135° the wind is 35° off the nose: drift 6°, groundspeed out 119 kt. Homebound on 315° the same wind is behind: groundspeed home 160 kt. Time to the point of safe return = endurance × home ÷ (out + home) = 190 min × 160 ÷ 279 = 109 min. The 340 NM distance is not needed for a point of safe return. The option originally printed here, 1 hr 44 min, does not follow from the data given and has been corrected.
