    I don't know the rules about that. Normally performance stall speeds are stated for fwd cg, it is rare for a manual to quote aft cg as well for a small airplane. Do the rules allow calculation or do they require specific test in which case a calibrated ASI is required etc etc?

    My copy of the POH has Vs of 62 mph CAS at aft cg, 64 at fwd cg.

    doesn’t apply to private operations My iPad Mini is a few years old and meets those CASA requirements anyway - they amended the text after the iPad Mini came out. I use my iPhone as a backup .... sometimes I just have the iPhone as sole source and that is legal - in that case my backup is memory and visual with mental calcs.

    I'd already discarded thoughts about the Emeraude and Minicab so ran out of ideas but .... let's go with Menestrel HN700.

    Vev, I know where, not when or what.

    1. You weren’t the only one. 2. Dunno what you refer to. I’ve come nowhere near crashing wrt this thread topic. 3. CASA decides the content of BAK. 4. I know about energy. 5. Not interested.

    Yep, but as others stated, whatever the AFM states. The Airtourer’s flaps do not deflect very much, incidentally, and the ailerons droop too. In a Husky I’d use full flap and their flaps are very effective.

    Many small GA airplanes have their best angle of climb with some flap deflected. Some require flap to comply with CASA's climb requirements of CAO 20.7.4.

    He still does not give the correct definition of Va.

    "Possible causes, or contributory factors, of an accident may be explored and opinion given based on the poster’s demonstrated reasons for giving such opinion."

    I guess that many are saved by the 50% margin between limit load factor (where the structure may deform) and ultimate load factor (structural failure) - I know of quite a few. These generally don't appear in accident reports. That Musketeer many years ago with buckled main spars and wing skins. Twisted steel tube truss, broken longerons, wing ribs broken etc on aerobatic airplanes. Still too many Aero Commanders with catastrophic wing failures not to mention Cessna 210s and Tiger Moths. https://www.flyingmag.com/technique/accidents/aerobatic-pilot-survives-extreme-failure

    1. Calculations must be done using CAS not IAS - that usually resolved most differences. 2. The flight envelope is determined at design stage, before the aeroplane has flown, based on estimated stall speed. The actual stall speed is often different than estimated and some manufacturers don’t bother revisiting the flight envelope! I can provide an example of this.

    I didn't see that either video actually explained the correct definition of Va (although I skipped thru that long video so may have missed it but don't think so as I didn't hear some aspects of Va mentioned at all). https://www.safepilots.org/documents/SAIB_Maneuvering_Speed.pdf

    I wasn't aware that any of the Meyers had a sliding canopy. I googled a bit and see that there are a few examples of Micco Aircraft Company MAC-145A?

    Seems like a common mount https://www.aircraftspruce.com/catalog/eppages/lordenginemountscessna_07-01131.php You could email Lord for the dimensions.

    A lot of aeroplanes on the ground today with the gusty wind. Let us know next time you visit.

    ASIC renewal

    djpacro replied to JG3's topic in Governing Bodies

    CASA really has nothing to do with ASICs.

    Yep, Jim is hard work to follow but he has much info available. "In pilot school, you might have been taught to “hold the nose up” during a turn. If so, did you ever consider that advice could kill you? Consider the fundamental fact that certified airplanes do not stall; pilots cause airplanes to stall." http://www.dylanaviation.com/stick-and-rudder-what-does-that-mean/ http://www.dylanaviation.com/avoid-loss-of-control-use-the-tape/ http://www.dylanaviation.com/bad-habits-and-improper-turns-can-be-deadly/ http://www.dylanaviation.com/dont-stall/

    The rule has changed, for one thing it refers to populous areas now.
