עד איזה גובה אפשר להגיע במטוס?
יש מי שבדק. - 28180 רגל!
Today I set out to find out how high my 8 would go. I did some level accel's from 2 to 18k to determine the climb performance and then came up with a climb schedule to do a ceiling climb. Taking off out of Mojave at 1600 lbs I used 120 KIAS to 10,000', 100 KIAS to 15,000', 90 KIAS to 20,000', 80 KIAS to 25,000', 75 KIAS to 27,000' then 70 KIAS which got me up to 28,000'.
Some observations. It's bloody cold up high. Aluminum is a great conductor of heat. Pens and iPhones don't work very well when cold. The RV-8 cabin heater is no match for -40C. The Dynon Skyview system stops reporting OAT below -32C.
The flight was spoiled by being passed as traffic to a jet climbing out of China Lake as "a very slow moving RV at 280". Granted 38 knots ground speed is a little on the slow side for an RV.
These planes really need a blower or turbo to increase the shabby high alt performance.

הם לא מוגבלים שלא לטוס בנתיבי ATS !!!
