What is the correct phraseology for changing the runway of a landing clearance?

The phraseology in the video was slightly incorrect at the time it was issued. Due to further clarifications, that phraseology is now even more of a departure from the current guidance. When that ...

When is the descent clearance requested from ATC?

Whether there are any formal policies for when to request descent will depend on the airline. However, I doubt formal procedures are established, since it should be pretty obvious to pilots when to ...

If I, as the ATC, give the instruction Cross [FIX] at 250 knots the expectation is that you will: At a distance from the fix adjust your speed to be at 250 knots ...

Is it bad form to call "ready to depart" when you know you won't be cleared yet?

From an ATC perspective - no, reporting ready for departure is not bad form, quite the opposite! The sooner we know you are ready, the sooner we can start planning other traffic to accommodate your ...

Can a non-IFR rated pilot accept an IFR clearance, provided the operation occurs in VMC only?

Operating as PIC under IFR always requires an instrument rating and currency, regardless of flight conditions. 14 CFR 61.3(e) requires the rating, and there's no exception for VFR conditions: (e) ...

Is it bad form to call "ready to depart" when you know you won't be cleared yet?

I see a contradiction in your question. In my experience, you do not receive an instruction to "Line Up and Wait" until after you call "Ready to Go". Once lined up and waiting, you should be doing ...

The main reasons I will instruct a pilot to intercept and follow the localiser instead of clearing him for the ILS are separation and minimum safe altitudes. In a busy approach environment, it is ...

How do you write 'to', 'then', or 'via' in IFR clearances shorthand symbols?

Do what works for you, and omit what you can. For example, "N123 is cleared to KABC" can be condensed to "ABC"... assuming the clearance is for you, why copy your own tail #? You're copying a ...
