Cobwebs... gone

Last weekend I had a quick trip to Masterton in Nanchang CJ6A, ZK-MAO. The weather was fantastic and the flying smooth.

One of the things I like about how we operate the Nanchang is that we have an Airswitch, instead of the typical Hobbs.

In most light aircraft, the Hobbs meter automatically starts ticking over soon after the engine starts. This is fine, and it allows for aircraft hire rates to appear lower, but it can cause some people [idiots all of them...] to rush the pre-takeoff procedures as they are paying the entire time the engine is running.

With an Airswitch, the timer only starts when your airspeed increases [typically on the takeoff roll] and finishes as you slow down after landing. The benefit of this is that pilots have no need to rush their start up, taxi, runup and shutdown procedures. This is particularly important in an aircraft with a larger engine, like the Nanchang with a 9 cylinder radial engine that needs time to warm up and cool down.

Anyway, the Airswitch time was only 0.6 hours (36 minutes) each way. On the trip to Masterton, this include an overhead rejoin, a touch and go and a second circuit before landing. On the way home, this included a look at the Orongorongo valley then back around to look at Mount Matthews.

 At owners rates, this is a fairly cheap day out 😀

Sounds like a great day out! You are having great fun and must be super happy to be part of the owners group, a great decision all round.

Yeah, good fun and (so far! :-) ) a good decision!
