S-TEC 60-2 requires re-trim after altitude hold?
Speaking of the S-Tec 60-2, I am transitioning to a Bonanza V35B that is
equipped with this AP. The previous owner demonstrated an idiosyncrasy with the AP that I would like to correct, if possible. Using the AP to hold VSI, the aircraft is in a climb. Upon reaching the assigned altitude, I push the ALT button on the AP. The aircraft, since it overshot the altitude by 100 feet or so, descends and levels off at the altitude where I engaged the ALT hold, then begins a speed increase to cruise speed. Now for the idiosyncrasy: The AP is engaged and the aircraft is holding perfectly at the desired altitude. However, if I disengage the AP, the aircraft immediately begins a climb, suggesting that there is a slight nose-up trim situation that was being held back by the AP. To overcome this, the previous owner suggested that after level-off, disengage the AP, manually re-trim, then re-engage the AP. How can the S-TEC AP be adjusted to hold the altitude after a climb without the nose-up trim problem? It seems to me that, over time, this problem could result in premature wear and tear of the AP control servos, no? -- Peter ----== Posted via Newsfeed.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeed.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= 19 East/West-Coast Specialized Servers - Total Privacy via Encryption =--- |
