  1. In my ERSA, INTRO-9 section 14.1 it clearly states runway lengths are shown as multiples of 100 feet but throughout ERSA all runway lengths are shown in metres. So, what am I missing here?

    ERSA does the conversion to feet for you (in hundreds of feet).

     

    for example.....

     

    YWOL airport diagram shows RWY 16/34 length to be 1819 metres.

     

    The Physical Characteristics shows a length of 60a, the conversion is - 1819m x 3.281 = 5968.139ft, so the 60a means the RWY is between 5900ft to 6000ft and the surface is asphalt or bitumen.

     

    Hope this helps.

  2. When you backtrack a runway you are supposed to be on the right side. So if you did have to pass another on a taxiway then i would think that would carry over as well. Most of the passing/ overtaking rules for aircraft are the same as maritime when you are in the air.

     

     

    That's not what I was told/instructed.

    best to backtrack (taxi) down the centreline....you're much easy to see

     

    Oh, turn so you can see the circuit and don't park on the keys...012_thumb_up.gif.cb3bc51429685855e5e23c55d661406e.gif

     

     

  3. That interpretation is a big stretch of 233(h) - it is about AIPs and Jepps etc. (That reg also applies to any flight, even if only a short hop along the runway, by the way.) The requirement for the pilot to study, nay carefully study, the weather is in CAR 239.As for that AWB on EFBs - I understand there will be some more info from CASA on this soon.

    That's interesting Dave...

     

    Most likely "printed copies" in Motz's post is where the confusion is.....

     

    Yes you're are right, printed copies do not need to be carried. However, the correct interpretation of CAR 233 and the AIP, requires a 'hard copy' of a wx brief to be carried. How that hard copy is obtained is left up to the PIC.

     

    I took Motz's "printed copy" comment as a 'hard copy' and, I would have thought others, knowing the rules of course, would have taken that the same way.

     

    Oh, for those copying a wx brief via phone, radio or other electronic means, obviously get the latest one, don't forget to jot down the issue and validity time, it might save some embarrassment if ramp checked down the track.

     

    And, storing aeronautical information locally on any electronic device and using it as your primary source of information is jumping the gun as far as the regulations are concerned regardless of what Mr OzRunways tells you. As Dave says, it's still works in progress with CASA at the present time, unless of course you have Class 1,2 or 3 EFB approval.

  4. Maybe this scenario has not been considered......

     

    "SYD CTR....."

     

    Twin 'ABC' cleared CN RNAV track DCT WC

     

    Contact CN TWR 120.1

     

    Traffic in your 2oclock 2miles 6500' unverified..

     

    "TWIN...."

     

    Cleared CN RNAV track DCT WC

     

    Contact CN TWR 120.1...traffic sighted...'ABC'.

     

    TWIN then changes to CN ATIS, prior to calling CN TWR approaching WC.

     

    No one interested because TWIN driver and SYD CTR well ahead of the game...

     

    Jab driver possibly oblivious to all this, whilst looking at acft below that's no threat, and allowing oneself to be in a position and at an altitude that is likely to conflict with IFR arrivals.

     

    Please post up the reply to the incident report.....012_thumb_up.gif.cb3bc51429685855e5e23c55d661406e.gif

  5. Update to my update:Ok, I tried to scan and OCR the text, it seems it isn't going to happen.Here is an extract from the manual.

     

    QUOTE

     

    (excuse any spelling mistakes, I am touch typing it in real time)

     

    Solution to type 1 wind triangles

     

    Given:

     

    Wind directio 45 deg

     

    Wind speed 20 mph

     

    true heading 276 deg

     

    true airspeed 130 mph

     

    Find:

     

    true course

     

    ground speed

     

    Solution: See fig 1 (yeah ok.)

     

    1 - set wind direction (45 deg) opposite true heading index by rotating compass ring.

     

    2 - move slide so as to place any conveninet whole number under grommet (centre of rotating disc)

     

    3 - Draw a line from the grommet 20 units (10 spaces) placing an arrow at the end of the wind line.

     

    (Strange they don't specify the direction - but it it TOWARDS YOU)

     

    4 - Rotate compass ring so that the true deading (276 deg) is opposite the true heading index.

     

    5 - move slide so that the true airspeed (130 mph) is under the grommet

     

    6 - ground speed (144 mph) is read at the end of the wind arrow along the speed circle.

     

    7 - since the wind is fro the right, the drift is left (6 deg). The end of the wind arrow is 6 spaces to the left of the true eading-airspeed line.

     

    8 - Opposite 6 divisions to the left of the true heading index, read true course (270 deg).

     

    Now, thinking about it again, it may be right. What I was "reading" was it showed you your course to steer. But obviously it doesn't.

     

    Somehow I think I should stop digging (talking) as it would now seem that things are "correct".

     

    However, I am still stuck on the other way the school told us to do things which was as confusing as....

     

    And probably didn't help me pass the exams.

     

    As I said, I shall shut up now.

    Okay, can see now where you're going wrong.....

     

    Here's how to solve the problem in your example -

     

    1. place wind (045/20) UNDER True Index, if the instructions you're reading say 'opposite' they actually mean UNDER

     

    2. mark wind speed (cross) (20kts) UP from the centre. In the photo below I've marked it from the 100kt mark, you can mark it from any speed mark. I've also drawn the wind vector to help visualise (In your example the wind is coming from 045T at 20kts).

     

    Wind.thumb.jpg.3f07d4c71d1ff1f6c9e0de929bda43bd.jpg

     

    Now,

     

    1. rotate compass ring so True Track (276) is UNDER True Index, again if the instruction you're reading say 'opposite' they actually mean UNDER.

     

    2. move card so TAS (130kts) is under your wind mark (cross)

     

    3. read drift, in this example = 7deg right, then read your Ground Speed = 141kts

     

    So the answer is -

     

    276 + 7 = 283T and a Ground Speed of 141kts.

    And, don't forget to apply the Magnetic Variation to determine your Magnetic Heading :))

     

    The best way to help visualise is to draw your track and wind direction on a map, that will clear up any confusion....

     

    Hope the above helps :))

  6. No Ossie, but judging from your posts you must be a highly intelligent fellow who knows a good thing when he is onto it so I must assume that you picked a wife who was also highly intelligent since she picked you, extremely attractive and in your eyes the 'Best in the world'.107_score_010.gif.2fa64cd6c3a0f3d769ce8a3c21d3ff90.gif. 008_roflmao.gif.692a1fa1bc264885482c2a384583e343.gifAlan.

    highly intelligent....nah, you must have me mixed up with someone else...

     

    I think she felt sorry for me.....she's actually said it a few times....012_thumb_up.gif.cb3bc51429685855e5e23c55d661406e.gif
