Flying In Marginal Weather: A Student Pilot Experience

Flying in marginal weather with an experienced instructor is a great way to gain experience and build confidence. As an aviation student, you will regularly be placed in unfamiliar situations that test your skill, airmanship and decision making. These judgements could even determine the entire outcome of a flight. It is paramount for all pilots to attain a weather briefing for all matters of flying, including flying circuits.

The 24th of September, 2017, was a definitive learning curb and monumental day for me in my aviation career. What was supposed to be a regular day of circuit flying soon turned into an unforeseen challenge.

The weather was marginal on that day, with gusts up to 20 knots and some showers, as the outer rainbands of a tropical depression were affecting us here in Hong Kong. However, it seemed safe enough to fly circuits at first glance.

Fly with an instructor who is comfortable with flying in marginal weather

This will allow you to test your limitations safely.

After pre-flight, I immediately requested not to be sent out solo due to the weather. Nevertheless, my instructor and I decided that today would be a wonderful opportunity to test my abilities safely under his supervision.

My instructor was comfortable with the conditions; however, we were both aware of a squall line brewing to the south of Hong Kong that could potentially affect us. We calculated that we had at least 45 minutes before the line hit, and we assumed we would be in the clear.

Think beyond the aviation weather briefing

Interpreting the weather does not stop there. It’s vital that you can visualise how the forecast can potentially affect your flight.

Heels to the floor, full power, RPMs in range, Ts and Ps in the green and as the aircraft passed 55 knots; I gently applied backpressure for a smooth take-off.

Almost as soon as I climbed above the tree-lines, the aircraft jolted to the right, and I corrected instinctively. I remembered exactly how to respond during turbulence – focus on holding the altitude of the plane, don’t chase the altitude and most importantly don’t bust manoeuvring speed.

As I rolled out on downwind, the aircraft was thrown around in all directions. My body, with the absence of double shoulder harnesses, was also thrown around alongside as the rain and turbulence worsened. I struggled but managed to get my pre-landing checks complete and radio call out. Despite my headset bumping the ceiling, in such turbulence, one must remember that the priority is always to fly the aircraft.

Fly the attitudes. It will save your life one day!

The final approach was terrible, the turbulence made me delay my full flaps selection and I felt as if the aircraft was being tossed around. It occurred to me that I was way too flat as I flared so I applied more back pressure to establish a landing attitude. Even so, it turns out that I was way too fast. I hit and bounced, holding the landing attitude before touching down once again. The conditions weren’t easing, and I really began to worry.

The rain and turbulence escalated and my headset fell off. The instructor took over as I tried to collect myself. It appeared the squall line on the radar image I saw before the flight was going to hit. I voiced to my instructor and knew that this was going to be a full stop.

Plan for unforeseen delays. Anything can close the runway

Prepared and eager to land, I rolled out on downwind, least expecting flight operations to declare a runway closure for 5 minutes over the radio.

The rain became menacing as I flew at circuit height and held, pelting onto the windshield, and obscuring my visibility. My instructor, however, remained silent to test my decision-making skills for flying in marginal weather.

Waiting for the all-clear seemed like forever. Panic began to set in as I came too close to losing control. “Don’t chase the instruments and hold the attitude,” I reminded myself.

“The runway is now all clear”

Thank goodness. My instructor sprang into action and decided to help me with radios. On the base leg, I set the appropriate attitude for 75 knots and trimmed—I feel very fortunate to be taught how to fly attitudes instead of chasing airspeed, the emphasis on attitude flying by Learn to Fly helped immensely.

Just as I was about to turn final, 75 knots plummeted to only 65 and I sank like a rock. I just had a wind shear of a 10-knot loss. Immediately I applied full power and performed a go-around.

On final approach, I focused on just flying by feel. The landing was hard; however, being back on the ground was all that mattered.

“A superior pilot uses his superior judgement to avoid situations which require the use of his superior skill” – Frank Borman, NASA Astronaut, Commander of Apollo 8

Fifteen minutes after landing, the squall line came through with heavy thunder and rain. It was at this moment I realised the outcome of today’s flight was merely a testament to my good judgement under pressure in a difficult situation. My instructor and I were both safe after I made the decision to call it off. It reiterated to me that as a student, we have the right to make a no-go decision! Because despite embracing every ounce of optimism, even for the simplest of tasks, it won’t change the weather outcome.

This flying in marginal weather experience strengthened my decision-making skills and confidence as a pilot. Contributed by LTF student Horace Ho.

How Flying Critical Incidents Can Occur

When an aircraft flying under Visual Flight Rules (VFR) enters Instrument Meteorological Conditions (IMC), flying critical incidents can sometimes occur. In most cases, this is due to reduced visibility or inadvertent entry into clouds. Both of which happen because of the loss of the natural horizon.

Unfortunately, such flying critical incidents have cost the lives of many pilots.

You hope it will never happen to you

Before I began my pilot journey, I always seemed to find the time to read unfortunate accident reports where a non-instrument rated pilot on a VFR flight enters IMC. It is even more unfortunate to realise that many of these incidents become fatal accidents. The more I’ve read, the more I’ve tried to make myself believe, ‘It will never happen to me!’

For non-pilots, all of these accidents seem preventable. Reading the Terminal Area Forecast (TAF) and good weather knowledge are all valid and effective strategies to combat any similar occurrence from happening. However, today I will write about a time when this happened to me on a training flight, nonetheless with an experienced instructor on board.

The importance of sharing stories

Before undertaking the task of writing it, I had been wondering about whether or not I should really share my story. However, I made the decision to do so knowing it could help educate other pilots and student pilots about when flying critical incidents can occur.

Cloudy conditions and lower visibility

It was a very cold morning after a cold front came through the day before. I checked the METAR of Hong Kong International Airport and the forecast indicated cloud covers clearing and rising to 2500 feet with 9 kilometres of visibility. However, as I arrived in the flight operations office, we received PIREPs from other pilots of temporary visibility reduction to an estimate of fewer than 3 kilometres near the high ground. I knew this could become an issue upon exiting the airfield area into the training area via a gap in the mountains.

The aircraft from previous slots were rocking the circuit and about to finalise their return. Skies above Shek Kong Airfield were clearing and let in some warm sunlight. However, the area towards the exit route (Kadoorie Gap) into the training area was still rather cloudy. I saw clouds on the other side of the mountains and thought this could really be an issue for our flight today – we had some instrument flying planned.

Climbing to 1500 feet

My instructor had nearly 40 years’ experience in the UK as an aerobatic pilot and warbird pilot. He also holds an Instrument Rating – Restricted on his CAA license – although on his Hong Kong license he does not hold such rating. Even so, his instructor rating allows him to teach basic instrument flying and tracking. On this day, despite the clouds, I put my trust in his judgement and was well aware of his capabilities since we had flown together numerous times.

We taxied out to the runway after our run-up checks, only to notice something very strange. Our slot was supposedly fully booked out with our entire fleet expected to fly. However, there was no action on the aircraft apron. I recall looking to my right as I prepared to shift into full power for takeoff and witnessing all the aircraft sitting idly, waiting for the weather to clear. Still, I thought there was no time to waste and we took off.

We climbed to 1500 feet and tracked towards the exit. As soon as we switched frequencies for traffic information service we heard a rescue helicopter saying, “Visibility deteriorating to less than 3000 meters.” I wasn’t sure where the helicopter was, but in retrospect, it really should’ve been the warning to turn back. We pressed on and exited out of the mountain gap and went on to “the other side,” where all the nasty clouds were, maintaining 1500 feet all the way through.

Scary in-flight sights

As soon as the mountains disappeared from my peripheral vision, my instructor and I realised that visibility was not 9 kilometres, as we had initially projected, and I could only see what was in front of us by looking downwards.

The only visibility I had was of the ground below, including the roads, trees and buildings of Tai Po. I looked back and realised that our only escape route back to the airfield would be obscured if we kept going. Just as I was about to turn back, it became apparent that my instructor had the same idea in mind. “Bring us back,” he said.

Returning through the mountain gap

The direction indicator on that particular Cessna 172 was somewhat defective. This meant I started my timer on my watch and began a rate one turn to the left. I timed for 1 minute, which at 3 degrees a second would be a full 180-degree turn. Fortunately, the mountain gap remained in view this entire time and I instinctively throttled up to return quickly. We were pushed even lower as we entered the airfield airspace, finally descending to 1300 feet. It was very uncomfortable watching the mountains on either side of me come so painfully close.

Lessons learnt

Of course, we were fortunate that despite this being a VFR into IMC incident. The visibility was still sufficient for a safe turn-back manoeuvre.

Among the contributing factors to the success of this was the expertise of my instructor, who holds a restricted instrument rating in the UK, and the fact that at this time I had already completed an hour of instrument flight training. A serious lesson in how flying critical incidents can occur.

After landing, and during the debrief, we narrowed the causes down to the ‘get-there-itis’ that occurred as a result of wanting to squeeze more instrument flying time in for me and also the fact that my instructor was instrument-rated and we put such confidence in his expertise. In retrospect, we shouldn’t have even left the ground in the first place.

This flying incident is proof that pilots with any amount of experience can be sucked into this veil of complacency. They then can make decisions which go against rational and safer judgement. It is an incident my instructor and I will both go on to remember.

Safe flying everyone!
