This came up while I was writing another message earlier today..

Is {Sal} (v) "ascend", to be treated as the verbs of movement ?

If I'm on earth and begin ascending to the sky, what do I say ?

{chal vIlSal} or {chalDaq jISal} ?

"Verb of movement" or "verb of motion" is really not a term we should have promoted so much. The defining feature is not that the verb describes motion or movement, but that the verb itself include a locative idea.

There are a few verbs whose meanings include locative notions, such as ghoS approach, proceed. The locative suffix need not be used on nouns which are the objects of such verbs.

Duj ghoStaH It is approaching the ship.
(Duj ship, vessel, ghoStaH it is approaching it)

yuQ wIghoStaH We are proceeding toward the planet.
(yuQ planet, wIghoStaH we are proceeding toward it)

If the locative suffix is used with such verbs, the resulting sentence is somewhat redundant, but not out-and-out wrong.

DujDaq ghoStaH It is approaching toward the ship.

So the question you need to answer is, does Sal ascend include a locative notion? I don't think so. Okrand uses Sal in paq'batlh like so:

SaqSub'e' muSHa'bogh
    pawmeH leng qeylIS
    HuDmey Sal ghIq ghIr

And Kahless traveled to
    His beloved Saq'suub,
    Over the mountains,

The object of Sal is the thing climbed, not the destination, so it doesn't appear to be a locative verb.

He uses it again:

QIStaq 'emDaq jenchoH jul
    yor DungDaq Salta'DI'
    tagh HarghchuqmeH poH

The sun rises high behind the Kri'stak,
    When it rises over its top,
    It is time to do battle.

Here, the destination of the rising is mentioned, and it is in a separate locative phrase, not the object of the verb. I am now convinced that Sal is not a locative verb.

I like that term much better: locative verb.
