How are taxi to and hold instructions given on an airport without taxiways to the runway end? In a smaller airport which still handles large commercial aircraft (i.e. Princess Juliana Int. Airport (TNCM), Robert L. Bradshaw Int. Airport (TKPK), etc.), what are the taxi instructions given? I don't want to just assume that an airliner would be given a taxi and hold short, but that is what I would expect.

Here is a diagram of Bradshaw Airport,

Let's say our commercial airliner is taking off from Runway 07. They get a Taxi To and Hold Short instruction preparatory to Cleared To Takeoff. Do they taxi to the end of ramp A and hold short? or do they go all the way to the turn around at the end of 07?  

If it's the end of A, what instruction allows then to enter and use the runway as a taxiway?
A is a taxiway, not the ramp. It will have stop bars and signs at the end. Here, the double solid lines are on the taxiway side and must not be crossed without clearance.

If the instruction is hold short, you hold at the end of Alpha.  

NB.  An active runway is never a taxiway.  The clearances and instructions are for runways, even when backtracking.

The initial clearance will likely be:


  Taxi via Alpha, hold short runway 07.


Followed by


  Line up runway 07 via backtrack and wait.


Then finally:


  cleared for take-off runway 07


The initial clearance might combine the first 2.


  Taxi via alpha, line up runway 07 via backtrack and wait


Note that the runway designator is always the departure runway so enter 25 and backtrack would not be used.
