View Full Version : Commercial precision landings
I'm taking my 2nd stab at my commercial checkride in a couple days.
Last week, I got through the Oral exam fine. We first flew my
instructor's Bonanza for the complex pattern work. Didn't do too bad on
the soft-field stuff, but I sailed right past my short-field mark by
about 300 feet. We then tried a short approach. Not even the 180 deg
accuracy landing. Just make the runway. Well, after several laps of
dropping the gear abeam the numbers, I did it again & came up well
short of the runway.
Pink slip.
I've gone up with my instructor to work on both accuracy landings, but
can't seem to hit them consistently. Any advice? Any examiners care to
tell how much "fudge" factor they may allow if I'm a little short or
long? If I am, can I request another try at it?
I haven't even had the chance to demonstrate the airwork in my Cherokee
yet (which I think will go much better). I'm hoping the DE will let me
do that stuff first & save the complex for last. But, since the complex
is what I failed the first time, I don't know if we have to complete
that first.
My CFI says I fly just fine, and I'm starting to feel more comfortable
in the Bo (only 7 hours so far). I've got 160+ in the Cherokee & 450
total. I'm just psyching myself out over 2 little landings.
Ugh.

With the Bo and a short approach put the gear down no later than 
midfield.  Full flaps, power off.  Turn base at the approach end, speed 
no more than 90 mph, assuming you and the FAA man on board.  One 
sweeping turn to final.  You can't land short if you don't go past the 
end of the runway.  Much better to roll off the end at a slow speed than 
  stall it in short.  You'll still only need 1000 feet of runway if you 
keep the speed to 85 mph on the downwind to base.

I don't know what everyone else thinks, but that does not seem like very
much time to transition into a Bo, to me.
Perhaps your instructor rushed you to the test, a little bit.
Nothing like practice.  Good practice, that is. <g>

Lands are all about controlling speed, the right speed.  1.3 
Vs(x) for the weight you're actually flying.  You didn't say 
what model Bonanza, but an A36 can be 800 pounds under 
certificated GW, or 25% under.  You must reduce your 
approach speed by the proper amount or you will float 
forever.  Beech does publish excellent TO and Landing graphs 
with speed adjustments.
You can fly a few knots, not more than 5, faster which will 
give you a steeper descent and then you can use the extra 
speed to slow down to get a better glide.  If you are using 
best glide speed there is nothing you can do to improve your 
approach without adding power.
You are likely flying too fast and too wide on downwind. 
You are also probably watching your gauges and airspeed as 
you configure the Bonanza for the approach, do it by sound 
and feel and watch the runway for relative motion (drift and 
glide path) and you should do fine.
Remember, you will get a landing gear failure and it may 
come in the pattern with a simulated engine failure.  Make 
sure you know the procedure and have checked during the 
pre-flight that the gear handle can be un-stowed [sometimes 
the spar cover is installed over the handle].  But also 
remember that it take 50 turns to get the gear down and you 
only have so much time.  If he gives you a simulated engine 
failure and then the gear fails, exercise your judgment, 
tell him that in a real case you'd land gear up rather than 
risk a crash while trying to crank the gear.  Then add power 
and go-around, crank the gear on downwind to show him you 
know how.  Sometimes an examiner will give you a task to see 
if you have fixated on the checkride and not the safety of 
the flight.

I don't know about you, Jim, but if I was working a real engine
failure, I'm not sure I'd have the presense of mind to even notice if
the gear down light came on or not :-)

Remember that Vsx gear down is about 15-20 mph slower than Vsx gear up.
Look it up in the charts.

Landing weight = w2
Max gross weight =w1
Stall speed landing weight, landing config = Vs1
Stall speed at max gross weight, landing config = Vs
[sqrt (w2/w1)*Vs] = Vs1

Jim, is there any speed that is best to fly when cranking the gear down 
by hand?

As others have mentioned, speed control and a tight pattern.  I'd rather be 
high and tight, guaranteed to make the runway and allowing a slip as an 
option, low and wide doesn't leave you that option.  Explaining your 
reasoning, as long as it's safe and correct, shows commercial knowledge.
My commercial ride was the last ride that I was able to take with our local 
DE.  He's a real parrot on checkrides and a great teacher.  When we were 
about 5ft agl on the 180 degree power off spot landing, he asked if we'd 
make the designated touchdown spot.  I responded confidently that we would 
because if we were short the ride would be over.  Then he asked what options 
I had to extend the glide "just in case"... Prop I said, pull the prop and 
reduce the disc drag.  "Ever done it?" he asks.  "Nope" by that time his 
hand was already on the prop control and it was coming back.  We floated an 
extra distance, I can't remember how far, but he laughed and said "See how 
that works? But think before you do it, you need oil pressure in a single" 
And with that our ride ended on a fun and informative note.

JM makes a good point.
A go-around or an engine out approach are great times for a DE to pull the 
gear circuit breaker while you're occupied with other things.
One thing that our DE, and I as well, try to drive into every commercial and 
or complex student is to keep your hand next to the gear handle until you 
get the "gear up" or "gear down" indications.  It will serve as a physical 
reminder to turn your eyes back to the indicators before your hand is 
returned to service.  Some will say to leave it on the handle, but those 
who've broken their gear handles off when hitting turbulence will tell you 
to just put your hand "near" the handle.

I've gone up with my CFI for a couple more flights just working the landings
in the Bonanza (A BE33, by the way). They're alot better, but once in a
while I'll still float past where I need to be.
I failed the first short-field because I was way long, and the short
approach was well below best glide with the gear hanging out & a very nose
high attitude at the very last. We would have made the runway, but he called
for a go-around. That apparently, was the final straw that ended the ride. I
agree it was a crappy approach.
Now I've got them more consistent. But once in a while, there's still a
floater I can't seem to get down, or a power off that's setup & safe, but
still short of my desired touchdown point. Ugh.

I had about 550 hours in a C172 before I moved up to a Bonanza and it took
me about 12 hours with an instructor to get (more or less) comfortable with
the added workload and speed of the aircraft.

Yeah, I would think.  Did you also have to pass a commercial checkride at
the end of the 12 hours?  I would think you would want to be more than  (in
your words) "more or less comfortable with the added workload and speed"
before you had to pass a checkride, with all of the added pressures and
nervousness that "automatically" comes with a checkride.

I like 1.5 Vs until on final, that provides a good margin 
for maneuvering with bank angles up to 30 degrees.  Yes you 
can calculate the proper speed, Beech does have the proper 
speeds on their performance charts, adjusted for actual 
weight.

Not at all.  This was just to move up to the aircraft, not to obtain my
commercial.   About half those hours were flying in real IMC to get used to
handling the aircraft in an IFR setting, which I don't believe is part of
the commercial training, is it?
In any regard, I doubt I would have passed the commercial checkride after
those 12 hours/

Too little time in the airplane to judge how it will respond to what you do.

I got my commercial due to being a military pilot so I only had to take a 
written test on civilian regulations.  Won't the examiner allow you to use 
power on final to drag it to the point you wish to land and then throttle to 
idle?  After I retired from the Air Force some friends let me be a member of 
their aero club for free in exchange for flight instruction.  This one guy 
had the same problem you're having.  He couldn't consistently land at the 
beginning of an actual short runway.  I asked him why he didn't take his 
base leg out a little further so he could drag it in with some power and 
then chop it at the runway.  His eyes got big and he said he didn't think 
that was legal.  I told him it was silly to purposely enter an uncontrolled 
event to avoid the POSSIBILITY of an engine failure and not having enough 
glide speed/path to get to the runway.  Sure, if you have a normal runway 
length you should set up so that with an engine failure in the pattern you 
can still make it to the runway.
You try not to deliberately enter a dangerous situation to avoid the 
possibility of something else happening.  But if the regs for the CHECK RIDE 
don't allow it you have to do it that way for the check ride only.  But not 
in a real very short field situation.

There's 2 accuracy landings for Commercial. A short-field (with power) and a
180 degree power off landing.
I took my re-test today & passed! Got passed the landings I missed in the Bo
& then got to do the airwork stuff in my Cherokee. Whew. Now I can start
reading up on CFI training.
As my CFI & I were putting away the Bonanza, we watched 4 F-16s (based here)
make a tight short approach to land. They make it look easy... ;-)
Thanks for all those who chipped in some advice.
