    replied to Question 710022
    Yep, this needs sorting out in the notes The aerodrome requirements vary according to when we are considering the issues. The rules change as we progress from SELECTION OF AERODROMES (you in dispatch finalising the flight details), COMMENCING TAKE-OFF (is it legal to get airborne), and then once airborne,...

    Increase in HEADWIND (or decrease in TAILWIND) .... first of all in the cockpit you will see an INCREASE in IAS (therefore TAS will also increase). The equilibrium of tha aircraft has been disturbed, and without pilot input, the aircraft will go above the intended flightpath due to the increase in lift....

    OK, in a steady wind, or if the wind is changing SLOWLY, everything is straight forward, IAS and TAS are steady (the relationship between the 2 given by considering pressure altitude and temperature shown on the back of your CRP5 and the relationship between TAS and GROUNDSPEED (GS) is logical:

    Effect of windshear:

    Consider an aircraft in level steady flight (no acceleration), at this moment, the forces acting on the aircraft are in equilibrium, so thrust equals drag, lift equals weight (this a simplified picture, but it will do for the discussion).

    So, what has all...

    Yes, this does need adjusting. I think we have feedback on this, so I will rewrite it. This wording is exactly as it appeared in in the old QB, so I will change it. As it is, a very poorly written question.

    replied to Contaminated runways
    Op Procedure questions are largely on definition. EU Regulation 965/2012 Annex I lists these:

    ANNEX I Definitions

    contaminated runway means a runway of which more than 25 % of the runway surface area within the required length and width being used is covered by the foll...

    IAS and TAS are not the same, but they are directly connected. Look at the back of your wiz wheel, for a given pressure altitude and temperature, if you increase IAS, the TAS also increases.

    So, if you you are on approach with an increasing headwind, in the cockpit the first thing you will...

    replied to Annexes
    There is a bit of confusion here I think - ICAO Annexes versus EASA documentation:

    ICAO Annexes I think you learn about in Air Law, but so far as Op Procedures goes, you need to be aware of what Annex 6 is:

    ICAO ANNEXES:
    ANNEX 1 Personnel Licensing
    ANNEX 2 Rules...

    Hi Tom,

    I hope this finds you well.

    I have problems posting the full content of my question on the forum and I was wondering if anybody could kindly clarify the ambiguity around the following question:

    Question ID: 711287, which states:
    "Which ICAO annex...
