Unfortunately, missed the live webinar, but just listen to playback. Nice refresher for some of the key elements and have a copy of the recent radiotelephony safety sense leaflet that was mentioned. Thanks
Thus is excellent and I've passed it on to my microlight buddies who generally fly from farm strips and don't get enough practice or have enough confidence.
Regarding " How will a controller say a QNH of 1000 hPa". The current online CAP413 (CAP413 E23 A1 effective date 21 January 2021) Page 27 states: 'Altimeter Settings, including units when value is below 1000 hectopascals'. Therefore, unless there has been a recent change of which I am not aware, your answer 'C' is incorrect. Please verify.
Hi Malcolm, the normal transmission would be “QNH xxxx” and hectopascals added for 999 and below - but hectopascals can be added for pressures of 1000 and above - for example if it was in a descent instruction and could cause confusion. The poll question was intended to explore the phraseology of the 1000 - this was the change we were referring to as it used to be said one zero zero zero. As hectopascals can be added we felt it was best to put it in, but of course many people picked up that it is normally not said - hope that helps, it has certainly generated a great debate and I think in future I would choose to not put hectopascals in and explain the 999 and below bit! Thanks for taking the time to write in.
MATS Part 1, Section 1, Chapter 6.2: 'When transmitting altimeter pressure settings that are lower than 1000 hPa, controllers are to specify clearly the unit of measurement and pay particular attention to the read-back'.
@@niallrobertson4262 Of course, and many of us probably know why. Conversely, units are not required when transmitting altimeter pressure settings which are 1000 hPa or above, consequently "QNH wun tousand" does NOT require the suffix "hectopascals".
@@astralaviationtv9977 Hello Astral. The suffix "hectopascals" is only required when the value is below 1000. (Your '999 and below' is, of course, not the same as 'below 1000'). Adding 'hectopascals' to pressures 1000 and above may delude the listener into believing that the pressure value has been mis-heard, and has the potential to trigger unnecessary repetition. This is where using 'discretion' by adding unnecessary words can cause confusion. "QNH Wun Tousand" is perfectly adequate, and I agree with your post-debate conclusion!
Very useful presentation, learnt a lot, however us all being human and all, telling me to have a read at several points in the presentation when it could have been simply explained to me there and then would have been better. After Discussion or a mention of a particular point, more examples please of them in use
"Do you always need to notify when entering our leaving an atz? Yes". That's what the law says but it's not what aircraft entering, for example, Gatwick atz do... so why doesn't the law apply to them or where are the exemptions listed?
Same here. I was unable to log into the live session but it was well worth viewing this. Thanks, guys.
Really enjoyed that, thanks so much for the session - and letting those who missed it to catch up! Definitely a good refresher for RT 👍
This was brilliant, thank you so much for sharing.

Thanks for this.
Thanks guys, missed the live session but just listened to the post, very informative like always.
No worries! Glad you enjoyed
