"Hold short of the RW"

[AMF]

Passenger 9 Hold Short = rubbish

Just like standard noise says - it is bad RT - and one day there will be a loud crunch as 2 aircraft meet.

It's perfectly acceptable and absolutely clear RT. The taxiway ends and the runway begins at the lines delineating the 2. Defining the 2 different areas are what the lines are for. Taxi past them and you're officially on the runway. Do so without a "Line up and wait", "Cleared for takeoff", or "Cleared to cross/back taxi" clearance earns you an incursion.

If there's a loud crunch after a pilot doesn't adhere to a "hold short of runway etc" clearance limit it will be on the head of the pilot who doesn't know their basic rules regarding signage and markings, and thinks it's up to them to decide where the "runway" begins after taxiing past paint on the pavement that defines it for them.

This is very, very basic stuff.

DOC 9432 - Manual of Radiotelephony


4.4 Taxi instructions

When a taxi clearance contains a taxi limit beyond a runway, it shall contain an explicit clearance to cross, or an instruction to hold short of that runway.

Example:

Fastair123 taxi holding point RWY 22 via taxiways BRAVO and CHARLIE, hold short of RWY 12.


Now making up your own phraseology... That's what's dangerous.
