• start on the runway or do Ctrl+E for Ready for Takeoff then wait for all the messages to
clear and rotor rpm to rise
• hold down CYCLIC TRIM RELEASE, you are now in control of the cyclic
• you don't need to hold down COLLECTIVE TRIM RELEASE because you have no upper
modes anyway (like ALT VS/FPA CR.HT)
• increase collective and take off normally
• (skip 4ft hover checks and standard takeoff procedure)
• hand fly to 500AGL
• T1: press AP/BKUP ON (observe that IAS, ALT and HDG modes are now engaged)
◦ use cyclic beep trim UP/DOWN: to control your IAS (pitch axis)
◦ use your cyclic beep trim LEFT/RIGHT: to control your HDG (roll axis)
◦ use your collective beep trim UP/DOWN: to control your ALT in 10ft increments
(collective axis)
•
eventually you can tap AP/GTC twice and you will go into GTC.H and auto hover after
heaving a bit

◦ hold down CYCLIC TRIM RELEASE and also COLLECTIVE TRIM RELEASE
◦ now you're in control and you can hand fly to the ground. Once you do you can release
all the controls and you will be sitting on the ground in FLIGHT and you can take the
engines to IDLE and then shutdown.

• lift off into a hover (without touching FTR, which seems to destabilize a slight climb to
hover -- and BTW I do have to inject some pedal to "stay straight").
• gain a little bit of altitude, and then engage AP/BKP On-Up, which pushes the nose over,
establishes a slow forward IAS target, and the current altitude (I think)
• Use the collective/cyclic beep trims to set a reasonable target speed, altitude, and heading.
• Assuming I have a flight plan loaded, engage NAV.

• Take off with hands on, manually piloting the helicopter (either with or without FTR, as
ATT is disabled on ground)
• gain stable hover and push FTR to center the trim and attitude mode
• From there, either use beeps in ATT mode and manual collective or use AFCS
• However, procedures require, after stable hover, to gain altitude and soeed in a safe way in
order to be safe in case of engine loss.
• Your goals are 3:
• Altitude
• speed
• safe emergency landing spot.
• You can see helicopters climbing backward to gain altitude while keeping the landing spot
in front, to be used in case of emergency.
• If you have a runway, after stable hover, accelerate to Vy and then climb.
• Use of APBKUP Up is ok. The function should keep your actual IAS.

The thing is, there is not just one single takeoff or landing. It always depends on the situation and
what you are trying to achieve. For example Andrewwww discribed a so called CAT A procedure
designed for helipad. Totally different to a takeoff from a runway.
Also, there is no general rule off how take offs are conducted regarding upper modes. Some might
want to use GTC, some might rather 'handfly' her to cruise and then engage ALT, HDG/NAV and
IAS. Some just might trim her out and don't use upper modes at all. So, there are no general rules or
procedures. There are just some things to consider (for example engine failure) that will influence
take off procedures.
Basically, as long as it's safe, its up to you
