But, look here

http://myweb.tiscali.co.uk/fssim/charts/LGSR.pdf

Approach plate 13-2, circling VOR/DME (sorry about the various links, its what I find in google)

Neither the gradient is excessive, neither the offset is excessive.
I could be wrong but on that VOR/DME procedure it looks like the final approach track doesn't intersect the runway centerline until past the runway threshold.

For an offset straight-in approach you'd ideally want the final approach track to intersect the extended runway centerline at a reasonable distance prior the threshold -- or at least be within a certain margin -- so the aircraft can be in a position to make the landing.

Regulatory requirements and aircraft procedures are there with some purpose which may not be visible to normal pilot unless he goes out of the way to find out. That is why one should just follow what is required and refrain from creating personal interpretations and options because it can be unsafe.

The FAA AIM says:

The fact that a straight−in minimum is not published does not preclude pilots from landing straight−in if they have the active runway in sight and have sufficient time to make a normal approach for landing. Under such conditions and when ATC has cleared them for landing on that runway, pilots are not expected to circle even though only circling minimums are published. If they desire to circle, they should advise ATC.
So Lantirn is correct about that. However, the original question was:

What should I understand from "clear for straight in app"?
The answer is as per the first reply: do not carry out the procedure turn.

Hi Lantirn,
Neither the gradient is excessive, neither the offset is excessive.
Would you circle?
In the case of LGSR VOR DME I would land "straight ahead" RWY 34 (Straight-in-Landing is not prohibited).

The VOR is physically to the East of the runway and the ideal approach would be from the West side of the extended centreline (not permitted due to terrain). Since the approach doesn't meet the requirements below, then only circle to land minima are published.


"6. Circling Approaches (General)
6.1 When is a circling approach published?
6.1.1 A circling MDA will normally be shown for a straight-in approach procedure to permit circling to other runways. However, where any of the requirements for a runway approach cannot be met, only a circling approach is published. These requirements are:
 Final approach course is not within the alignment criteria;
 Final approach gradient is too steep;
 Obstacles above the VSS (see Section 8.2.4); and
 Runway is not surveyed to the required standard."

Yep!

Look my post no8

Repeating my post:
Many old NDB procedures are "circling" procedures and have nothing to do with the approach track, but with terrain, obstacles and the navaid. Many of them are flown with a long final.
This is what I was talking about. By the way nice talk.

I don't see any unsafe deviation in this example. By the way this procedure is flown always straight in even in IMC.

Thank you everybody for all the contributions. Now I’ve downloaded the VOL 2 of 8168 and I have the check it carefully. Like Oggers said my first question was solved at the beginning but I think it’s confusing to have two different meaning for the same expression “straight-in app”.


Anyway,

Like Peekay4 said the track intercepts the runway after the threshold so you have to move the aircraft visually to align with the runway, that it's why it's circle-to-land and not straight in app (because doesn't meet the requirements). Like VOR's in Nice are circle-to-land (according to my FMS and my charts) and you have to follow the VPT (prescribed track to align with the runway) or like Mostar (LQMO - VOR 34). There is any definition for "straight-in landing"?.

And if you compare the charts for LGSR and LGTS with the VOR in LQMO, the Greeks don't said that the app is for a specific runway and the VOR in Mostar say that it's for runway 34, why this?
