Max descent gradient on final
If you are very high on a straight-in approach, and have to make the max descent gradient to be stabilized on short final, you need max drag (final-landing configuration), throttles idle, and then:
- Vmax for your configuration - Vref (+ additives) - Depend on the AC type Thanks :) |
Generally, from a practical point of view, gear and flaps (full) and speed at the flap limit, throttles closed. Some types allow spoilers in this case, but beware, sometimes very large rates of descent can develop.
But a better idea is to plan ahead a little better, ATC cooperating, of course. |
Is this meant to be a part of another thread (i.e. an answer to someone's question)?
If so, let me (or one of the other mods/admins) know, and I'll merge the threads. |
No thanks, it was me asking the best way of loosing altitude if you are very high on final and try to land (of course, stabilized)
|
Ok, thanks ... sorry for the confusion :)

Generally in anything larger that the B737 the idea is not to start a 'large'+1000 fpm'close to the ground,under 1000'agl.
It's generally understood that in this situ'one should be considering the Overshoot.The B727 taught the industry to avoid the practice.Sometimes it's more beneficial(I not going to say prudent)to keep the power on(spooled) and take a higher airspeed(within reason)keeping in mind the extra runway required.:rolleyes: |
