Cut off reverse thrust in 747, which one to follow?

Question:
i encountered 2 different sets of answers in 2 different 747 sim manual. one says to cut off the reverse thrust at 60kts, while another says 80. does it depend on rwy length/landing weight to choose which speed to cut off, or is it a recommendation to cut off at 80 at all times. however cutting off at 80 still leaves me with quite alot of speed to reduce using the brakes/autobrakes. and at high speed i'm not comfortable exiting the rwy. so this question is for the experienced 747 pilots, which speed is correct?

Answers:

Its not easy to become a pilot right now..in the future will it be so easy to learn to fly a plane as a car?

When to come out of reverse is largely dependent on airline procedures. Our airline calls for beginning to come out of reverse at about 80 kts and to be fully out of reverse by 60 kts. This is true across all our fleet, not just wide-bodies. The primary reason is FOD, keeping debris from ingesting into the engine.
If you are using autobrakes the deceleration rate should remain the same. Autobrakes on all landings is our procedure as this has been found to extend brake life (according to maintenance). Autobrakes in combination with reverse thrust will give a predetermined deceleration rate, MIN, MED, or MAX, whatever you feel is appropriate given the runway and conditions. As reverse thrust becomes less effective the autobrake system will apply more braking to keep that selected deceleration. Most pilots will kick off the autobrakes as they begin to take control of the aircraft on the roll out and have a particular exit in mind. I do it about the time I reach for nosewheel steering.
Another rule of thumb is no "double digit" turns on sharper turns. (Use the INS readout to be less than 10 kts)

SVFR vs. DVFR?

That depends on the headwind, runway conditions and etc. NOT necessary to go by the book.

Some sophiscated airports will give you indication with direction and at what speed to descend.

How tall are the Wheels on a 747 Jumbo Jet?

I believe its mainly for FOD reasons (foreign object damage). At slower speeds you run the risk of injesting debris that is blown off the ground by the reversers, especially on wing mounted engines. Fuselage mounted engines like on a CRJ, have less of a chance of doing this, but it is still worth stowing the reversers ahead of time. It only takes a small pebble to destroy an engine.
