More Navigation and an Amazing Autumn Day

I flew this week on Wednesday - curse those work commitments. Work might prove to be inconvenient for the next few weeks too. It was as fine a day as one could hope for, very light winds, blue skies and reasonable visibility. Barrie had asked me to plan a route from Blackbushe via Membury to Overton near Basingstoke and back to Blackbushe.



I'd has some frustration with the flight computer - so many terrible instructions and bad videos trying to "help".  Before my lesson I checked the winds aloft via form 214 and the weather with METAR and TAF on the Met Office web site (rather than relying on Apps!). I filled out my PLOG with info I was a bit uncertain about - both which F214 area to use and dodgy calculations. I didn't think there would be many problems since the wind was a very light 5kts at 2000ft. I did the common sense checks with wind direction and that seemed reasonable, though speeds seemed odd. I cross checked with Flight Demon but they had different answers. So I headed off to the airfield for real advice.

Once again we were in Tango-Echo, the runway was 25 and for a change the surface winds were calm.

Another solid briefing session glossed over the flight computer stuff, pointed me to the correct area of the F214 wind chart (between Heathrow and Bristol - which we are, rather than Jersey...). The winds for this region were much stronger, 20kts, so a swift re-calculation with dodgy flight computer technique and we were off.

As planned we departed overhead and again I wobbled around the airspace. We were running today via heading, speed and timings. As you can see from the map segment above we should have been north of R101, sadly no, we were too far south! Already very wrong, though Barrie did point out that the wind wasn't as strong as advertised so we adjusted the correction (halved our calculated amount (was 10º adjusted to 5º). We got back on the new heading and pressed on, checking out waypoints based on time as we went. I'd divided the legs into quarters before we started and calculated times. So now it was in action - so many minutes into the leg - what can we see here? What should we see? We pressed on to Membury. Today Barrie made sure I did my radio and FREDA checks as we went along. Again a bit of random turning when all of that happened.

I wasn't very positive in my corrections and I could see the motorway way to the north when in fact we should have crossed it. Eventually I spotted the tall aerial at Membury again way north of our position. I turned the plane that way and after a bit of circling above the services and airfield we set off on the second leg.

This leg I made more adjustments based on the ground below. The Kingsclere masts were very useful again and we arrived at Overton on time and as planned. The only problem was it was right under the nose and had to have it pointed out to me!

We circled Overton familiarising with features - using a country road isn't much use because they're difficult to spot from the air.

Finally we headed back again using timings and features until we once again had to head north for the appropriate Blackbushe join.

Barrie said we'd practice a variation via Reading next time and if he thought I was up to the radio, FREDA and flying I'd be off for my first solo cross country!

First Navigation Exercise

This week I launched into a new chapter of flying - navigation. From my initial lesson there seems to be as much to do as there was running up to the solo!



It was a strange day for weather. The forecast indicated a front arriving later in the day, but we were currently experiencing rain from an extended finger which was to clear to the North in the next hour - just time for a briefing. Barrie ran though the brief for this exercise and there's a write up of my notes at the end, though for this exercise we estimated headings and timings. As predicted the sky brightened and we headed off with some haste. Once again we were in Tango-Echo - not sign of Alpha-November though Barrie mentioned the possibility of new aircraft with the take-over. Runway 25 was in use and the wind was calm. We did the power checks on taxiway Hotel - a Twin Otter was coming in and we were keeping clear.

We took off and entered the circuit pattern, though rather than maintain 80ft we turned short on downwind and continued to climb, finally over the runway but climbing 1000-2000ft. I radioed Farnborough - not very smooth considering last month's practice and we began the first leg.

Accuracy of flight is important doing this and I'm not very accurate! Every glimpse into the cockpit or radio call and we start turning. We did a little kink to the south in our outward flight to avoid reastricted airspace R101 - AWE.

We'd passed AWE and there was a great grey wall of rain and cloud in front of us in the distance blocking the view of Greenham and Newbury - time for a change of plan. We flew a little closer and Barrie pointed out Greenam and then he positioned the aircraft over Kingsclere so that we could join the second leg.

Here we did some landmark spotting - identifying Basingstoke by the railway line and motorway. After a few minutes of this we took up our new heading - this time for home.

All approaches to Blackbushe are from the North, so we diverted to finally arrive dead-side.

An amazing lesson with some spectacular weather visuals. There were even a few scattered clouds at 800ft over Blackbushe which we had to dodge.

Notes

There are two major things to think about in a flight - Planning and the Flight.

Planning

1. Weather

This must be relevant to the route and should be check via the following Met Office services
  • TAF - forecast
  • METAR - weather 
  • Form 215 - significant weather chart

2. Plot route on the chart
  • Track
  • Minimum Safe Altitude (MSA) - large purple numbers e.g. 13 = 1300 ft
  • Planned Altitude - add 1000ft to MSA
  • Danger / Restricted Areas e.g. R101 2.4 - choose to fly around



3. Decide TAS & Power Settings
  • Affected by temperature and altitude
  • Work out leg times
4. Complete PLOG

5. Fuel Plan
  • Required
  • Onboard
6. Weights and Balances
  • Gross weight
  • Passengers
  • Fuel
  • Baggage
7. Landing Away
  • Destination airfield details
8. NOTAMS 
  • Normally done with the weather as could inform a go/no-go decision.
9. Check Aircraft

Flight

1. Cockpit organisation
  • Maps
  • Knee board

2. Departure procedure
  • Overhead Departure

3. En-Route 
  • Maintain heading & height
  • Lookout 
  • LAI
  • FREDA
  • Radio
  • Update & ref PLOG
  • Destination & turning

Keeping my hand in

I did a few circuits last week with 1200 ft clouds and failing visibility. We started late to let some showers pass. I hadn't flown for a month so it felt good to be back. The runway was 25 and the plane was Tango Echo. Wind was very light though there was the odd gust and some turbulence from the close clouds above. My landing were quite gentle, but off centre.

I also did a practice rejoin dead side, just for Barrie's entertainment I think.

Once again I've booked a double lesson next to tray and start navigation.
