In the last lesson I performed 30 degree (rate one) turns to the left and right. You may think it seems trivial, however there is a lot to turning a plane. The following need to be taken into consideration:
- Sitting on the left means left hand turns the nose will sit on the horizon to keep altitude
- Sitting on the left means right hand turns will look like the plane is diving to the ground, however it is staying on the altitude. This is due to the left hand seat being higher than the right in a right hand turn.
- Look out from the opposite side to where you are turning, then over the nose to the direction you are turning
- Maintaining altitude by
outside references. Instruments are not constantly scanned. They are only used to verify what you are seeing outside. So scan for traffic in the 2 second per segment sections, all across the screen (12 seconds maybe), then back across the instruments to make sure you haven't lost / gained height, speed, Temperatures and Pressures All OK? then back to the lookout. Hence lookout is the main priority
- Scanning for traffic. The eye only focuses a couple of meters in front of where you are looking, therefore you need to force the focus on a far away landmark, whilst scanning for traffic.
Lookout is so important, because in the UK when we get a nice and sunny day it brings everyone out for local flights. It is not uncommon for a general aviation airport, such as Shoreham (my home airport) to have 4 planes in the hold on the ground, while 4 or 5 are busy in the circuit maintaining separation waiting to land.
Today in the flight we practised climbing and descending turns with variable power:
- gliding descend (6% idle power)
- 15% power
- 25% power
- 40% power
all to note the rate of descent.
POWER - governs the rate of descent
ATTITUDE - governs the speed
Some lesson facts...
+ In a 30 degree bank 5 knots will be lost in airspeed
+ Lookout over opposite shoulder first, then lookout into the turn
+ Right hand turn needs more rudder than left hand turn due to the slipstream over the rudder in a climb (especially) or cruise
+ left hand turn doesn't need as much rudder due to slipstream from the prop (if spins clockwise as most GA (general aviation) aircraft do, such as the DA40, PA28 Cessna 150/152 etc.
+ Back pressure is needed to maintain altitude, look at the VSI (pictured below) this gives an accurate pre warning over the Altimeter (on the G1000 there is even a purple tape which shows what the Altitude loss/gain will be in 7 seconds time...clever - wonder why I want to learn on this type?!)
+ Climbing turn ONLY 15 DEGREES OF BANK (otherwise rate of climb is lost due to drag in higher wing). Also stall speed is increased. (30 degrees is 1.5g therefore stall speed increases)
+ Descending turn 30 Degrees of Bank as gravity helps us out here. Monitor speed.
The approach to Shoreham was non-eventful I made the following Radio Calls:
ME: 'Shoreham Tower, Golf Echo Kilo Currently Overhead Bognor, Altitude 3300 feet, Information Echo, QNH 1025. Request Crosswind Join Runway Two Zero'
ATC: 'Golf Echo Kilo Report ABeam Worthing Pier'
ME: 'Report Worthing Pier, Golf Echo Kilo'
OR I think it could have been...
ME: 'Wilko, Golf Echo Kilo'
To state that I will comply with your request....Nevermind, I will try that next time and see how impressed Dave is!
Can I just add it is hard (and fun) to read the descending checklist and note down new QNH's, Runways, Wind Speeds etc while flying and looking out for other traffic! But I am so pleased Dave has given me this responsibility so early on. It shows two things, I am slightly competant to do this and, as mentioned before I like this as I am increasing the amount of workload I do for myself.
ME: ' Golf Echo Kilo Is At Worthing Pier'
Then Shoreham Tower made us pass over to Approach and told us our position in the circuit (which we sneaked in front of a PA28 who was making a very wide crosswind leg). I aimed for the numbers on the opposite end to landing for the crosswind join.
The circuit is a rectangle really...
- Crosswind flying over and away from the runway
- Downwind is adjacent to the runway
- Base leg is flying back to the runway
- Finals is flying toward the runway to land
I made the crosswind join with 50% power, reminded to me by Dave. I was then following a PA28 where I had to give sufficient spacing before turning onto downwind. I obviously did this well as Dave didn't say anything! No news is good news and all :o)
Anyway, following this PA28 on downwind Dave said 'he is flying a bomber circuit' which I didn't have a clue what it was, but now i do! Down to the end of the downwind I made a left turn to the base leg aiming to the left of the chimney in the vincinity, over the hills.
I then spotted an aircraft lined up on runway two zero for takeoff and said to Dave, the PA28 in front of us will need to go around! Which he did, however it left us sufficient space to land.
The approach was more bumpy than I thought with a 10 knot wind. However I kept it on the extended centre line and Dave said 'I'm going to follow you through on this'. Right, this is all me now landing this £200k piece of equipment (however you don't think that at the time, at the time I'm focused on doing the best job I can, there is pressure, but not monitary value pressure) I felt Dave give some firm inputs to the control stick while I was landing. It was such a smooth landing...
I can only think Dave did this one, but give me some credit for it!
Can't wait for a low speed wind to nail the landing...The next lesson (below) is not looking too good with 30mph gusts...I wonder if I will fly...
NEXT LESSON: Wednesday 6th May (fingers x'd for weather)
