Yeah, that is the only logical reason, but why does it say DH and not DA???

 

It says "DH OR DA"

 

Choose the one that applies... I guess they put that in there in case you'd be expecting to fly a CATIII on your way back, right?

 

They always leave it open to pilot judgement anyway.

Nothing to do with navigraph, it is a performance thing. The standard one engine acceleration altitude in the books is 1500'. Some airlines use as low as 800' as a standard when they have the means to calculate airfield specific single engine accel alts with an EFB performance tool. Just stick to 1500', works everywhere

 

Why are you attributing to me a post i never made?

 

 

but think i'm bogging myself down

 

I know I'm quoting this out of context, and I know I've mentioned this before, but I think you're just bogging yourself down by trying to drink from a firehose.

 

Speaking as someone who reads, collects, and otherwise studies aviation information nearly obsessively, I totally get it.  I really truly understand the desire to learn everything possible about aviation, and airplanes, and the associated procedures.  The problem is, you're so thirsty for information that it seems that you're jumping from topic to topic "learning" too much, too fast.

 

Having been an instructor, the very last thing I want to do is kill your desire to learn, but as I've mentioned before: slow down.  Take time to absorb topics before moving on.  I think if you'd taken time to learn past topics - and I'm talking understand them intimately - you wouldn't have asked this question.

 

Why?

 

It's answered in tutorial 1.

 

 

 

Slow down.  Nobody is rushing you through this.  A willingness to learn is absolutely amazing - and rather refreshing, as so many others here seem uninterested and unwilling to learn - and it should be celebrated.  Just ensure you're giving your learning enough time to take hold.  Take one concept.  Learn it intimately.

 

In the wise words of [fill in the blank]:

"One cannot start a fire with a magnifying glass by moving it around.  One must hold the magnifying glass in one area to focus the light intensely.  Only then will a fire start and spread."

 

The same can be said for learning new knowledge.
