Some of the best video I’ve seen on YouTube of flying is in the evening – after the sun has set. Being able to fly at night obviously extends the useful flying day and also improves the options for waiting out weather and other potential delays. I’m a firm believer in having options to decrease the risk of acute get-there-itis.
With this in mind I’m setting off on my first post-PPL rating – the night rating. Interestingly we have the night rating as a separate rating instead of built into the PPL like it is in the United States. The requirements are not onerous but definitely stipulate dedicated experience in the dark – at least 3 circuits at night (I’ll be doing many more), 10 hours of instrument training (5 of which can be in the sim), a 150nm cross country by night and a theoretical exam.
As it stands currently, I’ve done 7 odd hours in the sim – all hard IFR flying and have enjoyed it quite a lot – I’m sure it’s the wasted youth playing Microsoft Flight simulator but at least I have some theoretical knowledge to hang onto that experience. So it’s actual night time flying I need – and this is what I did last night…
|Date of Flight||Aircraft||Route||IF Actual||Time(hrs)||Total(hrs)|
|19 July 2018||ZS-ZIP (SR20)||FALA(Lanseria, Johannesburg) - FALA||1.3||1.6||83.6|
So. Flying at night. It’s… well…. dark. In fact this surprised me because I was anticipating that the lights on the plane would be better than they are. They’re not great for taxiing on the apron so that took a little getting used to. The lighting on the taxiways at Lanseria is great so that wasn’t an issue. No delays fro other aircraft on the field while taxiing which is always a plus. Run up and pre departure checks were as per normal, although I chuckled at my instructor when she said that we’d aim for the darkest patch off the end of the runway if we lost and engine, we’d turn on the landing light, and if we didn’t like what we saw we’d turn it off again. This did bring home the stark reality of night flying – it’s really difficult to find a safe landing spot should the big fan in front decide to stop. Lining up on 07 you get the sense of how dark it is – a row of lights leading out into almost infinity and just blackness beyond – not a sliver of moon in sight even.
Performance in ZS-ZIP was pleasantly surprising – 9 celsius outside temp will do that and climb out was brisk (for an SR20). The instructor had me on the gauges almost immediately after takeoff and I flew the numbers – 5deg nose up with 50% flaps at full power gave me just over 85kts (Vy) so we were at CAPS height crossing the 25 threshold which was reassuring. Then it was head down in the cockpit. The aim of the flight was instrument navigation introduction – I’ve done lots of sim time but this felt somewhat easier I thought. We did a number of VOR radial intercepts under the Lanseria TMA – I must say that the VOR intercepts are reasonably easy with it being a command instrument – fly to the needle and the only tricky bit is remembering which reciprocal to use (FROM top TO bottom). Then we climbed out into the practice area for some upper air work – clean and configured stalls (no problem) and some steep turns – again not an issue which is quite funny considering how much difficulty I had with them prior to my PPL practical test.
Then some timed turns which are challenging – essentially we work out an angle of bank for the rate one turn (TAS divided by 10 plus 6-7kts) which at 130kts TAS works out to be around 20deg. Then set up on a radial, bank in to the rate one bank angle, start the timer and then try and maintain 45deg of heading change every 15seconds – 3 deg per second. Not quite as easy as it sounds but very rewarding to get right. These will be useful later in IF training when it comes to holding patterns and procedure turns. Then it was time for some ADF work. ADF navigation puzzles me from a number of aspects. Firstly, it’s a big drain on my brain to figure out which way to turn each time and secondly, they’re essentially obsolete. They’re so obsolete, in fact that our 2004 model SR20 G2 has no ADF radio on board. As a result, we have to bodge an ADF navigation exercise by using the bearing needle on the HSI to point to a GPS location and then fly using that as an ADF station. It gets the job done and perhaps it’s ADF as ADF should have been.
Still, ADF intercepts are fiddly. Intellectually I know it’s a simple case of remembering where one is in relation to the station and turning appropriately. The little tricks – turning away from the desired QDM inbound and towards and beyond QDR for the outbound – do help, but they’re not intuitive – I’m guessing that practice practice practice will be the key to successful ADF navigation. Finishing up with some unusual attitude recovery (again, fun…) I considered we’d done some good work. So what is it like flying at night? I found it really serene – its you and the plane – I didn’t hear any nighttime rough running and the air was smooth (and freezing – note to self – take a better jersey next time) and calm. The lights stretch for miles and the dark patches do feel like they’re reaching up to grab you – I assumed all the dark patches are mountains because why would anyone put lights on a mountain? The best part for me is that the feeling is getting better – i.e I’m flying more by the seat of my pants than I have been before and it feels smoother – I do need to be a little bit less aggressive on my turns – I do tend to roll quite positively which works during the day but perhaps not as well under instrument conditions!
We decided we were chilled enough and headed back for Lanseria. One scheduled 737 on long final and then we were to roll in onto approach. The night time approach is easier, and harder than I thought. Flying the profile is easier than during the day as less gusts and updrafts but the roundout and landing was very different. The instructor was following me on the controls – we went over the threshold at what I felt was the right height having had 2 red and 2 white on the PAPI the whole way down. Then she says “do you feel like you’re sitting on the runway?” and I say, “Um… yes?” and she says, “OK, go to idle” and we touch down light as a feather – best landing ever I think. Which would be awesome, except in my mind we were about 5feet higher and I wasn’t expecting the touchdown at that point. This confused me a little as I was convinced that one would feel lower coming in at night. There is no centreline marking on the runway so the only visual reference is the side lighting – guess I need to pay more attention to that in the coming flights – which should be two sessions of night circuits. Can’t wait.
