QUESTION: Greets Mr Marc
I was thinking that since you have an interest in aviation you may be able to help me with this.
I know that a helicopter moves foward when the pilot tilts the rotor forward, but how does he increase its foward speed?
Is the AH-64 Apache Longbow a high altitude helicopter, and what is ur aviation web add sir?

ANSWER: Tilting the rotor forward also causes the nose of the helicopter to go slightly below the horizon.  This, and an increase in engine RPM (revolutions per minute) are what causes a helicopter to increase speed.

My website is http://www.angelfire.com/pa3/cadet985 .  I have not worked on it in a very long time.

Hope this information helps.

QUESTION: What is the service ceiling of the AH-64 Apache and the chinook?

Answer
AH-64 A/D Apache - 21,000 feet (6400 meters) with an absolute minimum load.
CH-47D Chinook - 18,500 feet (5640 meters)

Note that while they are capable of flying this high, I have never heard of either helicopter being used at such a high altitude.  Keep in mind that over 10,000 feet there would need to be oxygen on board, and the on the CH-47 for example, the interior is somewhat exposed to weather conditions, as the loading ramp does not totally close...it is open at the top.  And with regards to the Apache, most missions are flown at low altitudes, some are even flown as low as treetop level.

Hope this information helps.
