Speeds high
With the gear down the GPWS thinks the aircraft is going to land, and therefore automatically inhibits the "Terrain Terrain Pull up" warning, however if terrain closerure rate is excessive will give a "Sink Rate" warning instead.
Can you please expand on the above? Please excuse my ignorance but I'm a very steep learning curve and as I don't fly and have enough trouble operating my mobile telephone all this technical information tends to take along time to sink in. Plus every pilot I talk to seems to have a different interpretation, even those in airlines.
Do you mean if you're descent rate is excessive you will receive a "Sink rate" warning?
cheers,
