At what time was this METAR issued?
- A0630 IST
- B0230 UTC
- C0230 IST
Why that is the answer
**Relevant data**
The date-time group of this METAR is **160230Z**.
**Interpretation**
The group has six figures and the letter Z:
- **16** = day of the month (the 16th)
- **0230** = time of the observation in hours and minutes
- **Z** = UTC (Coordinated Universal Time, also called 'Zulu')
All METAR times are in UTC, never local time, so that reports from every country use one clock.
**Reasoning**
The Z shows that the time is 0230 **UTC**, not IST. Indian Standard Time is UTC + 5 hours 30 minutes, so 0230 UTC is 0800 IST. Neither 0230 IST nor 0630 IST is correct.
**Correct answer**
The METAR was issued at **0230 UTC**.
**Remember for DGCA:** IST = UTC + 5:30. Every time in a METAR, SPECI, TREND or TAF is UTC.

"WS RWY28" in a METAR indicates that wind shear has been reported for runway 28 in the:
- ATake off path
- BApproach path
- CBoth take off and approach paths
Why that is the answer
**Concept**
**Wind shear** is a change in wind speed or direction over a short distance. Near the ground it is dangerous because a sudden loss of headwind, or a downdraught, reduces airspeed and lift while the aircraft is low and slow: in the climb after take-off or on final approach.
**Explanation**
When wind shear has been reported (usually by pilots) or detected between runway level and about **1,600 ft (500 m)**, the METAR adds it as supplementary information at the end: **WS RWY28** (or WS R28) for one runway, or **WS ALL RWY** for all runways.
The group does not say whether the shear was met on climb-out or on approach. It covers the **take-off path and the approach path** of that runway, so every pilot using runway 28, departing or arriving, should treat it as a warning.
**Applying it to the question**
WS RWY28 warns of wind shear for runway 28 in **both take off and approach paths**. Older formats had separate groups for take-off (WS TKOF) and landing (WS LDG); the present group covers both.
**Remember for DGCA:** WS RWYnn = wind shear below about 1,600 ft along the take-off or approach path of that runway; WS ALL RWY = all runways.

Frequently asked
How many AERODROME MET REPORTS METAR SPECI AND TREND questions are there for the DGCA CPL Aviation Meteorology paper?
Avielevate's bank carries 42 published AERODROME MET REPORTS METAR SPECI AND TREND questions for Aviation Meteorology, mapped across 1 learning objective. Every one has its answer key, and explanations are being written across the whole bank.
How much of the Aviation Meteorology paper is AERODROME MET REPORTS METAR SPECI AND TREND?
The DGCA does not publish a per-chapter breakdown of its papers, so nobody can honestly tell you — and we will not guess. What we can tell you is what students who have just sat a paper reported meeting, which is measured rather than rumoured: that is the exam recall report inside the app.
What is the best way to revise AERODROME MET REPORTS METAR SPECI AND TREND?
Sit a short timed set on this chapter alone, tag how sure you were of each answer, then drill the two that actually leak marks: the ones you got right while guessing, and the ones you got wrong while confident. Avielevate does that tagging for you and puts anything you got wrong back in front of you on a spaced schedule.
