Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Airwork, Turns, Climbs and Decends
<br clear="all">
== Airwork, Turns, Climbs and Decends Descends ==
OK - Now let's have some fun and leave the boring straight and level thing and go for some airwork. We skip the usual clearing turn here, because we don't care about any other virtual aircraft around us.
=== Climbs and Decends Descends ==='''D-GEAR on course climb altitude 4000ft, maintain for 1 minute, thereafter decend descend altitude 3000ft'''
To climb, the aircraft needs more power and less speed. That means the engines need better cooling, so first thing to do is open the cowl flaps. Climb power will be at 75% max power. The according power setting is 32" manifold pressure and 2500RPM. When increasing power, always increase RPM first before increasing manifold pressure. Increase pitch (pull yoke backwards) to some 5 degrees and slow down to 100 knots indicated.
When reaching the target altitude, level off exactly like you did after takeoff. Reduce power to 28"/2400RPM and close the cowl flaps.
After one minute start the decentdescent. Reduce power to 21" and 2300RPM. Reduce manifold pressure before decreasing RPM. Leave the cowl flaps closed to keep the engines warm. Pitch down 3-4 degrees to maintain a rate of decent descent of 500-1000 feet per minute.
Never decent descent with an idle engine to avoid shock-cooling and severe engine damage.
When reaching the target altitude of 3000ft, reset power to 28"/2400RPM (remember: increase RPM first), pitch up and accelerate to cruise speed.
