FLYING THE TWIN OTTER

Flying the Twin Otter is remarkably easy. The aircraft is stable, reliable and even close to the ragged edge of

the flight envelope will be predictable. YouTube is full of videos of Twin Otters doing the most amazing

things. From landings in high winds to going vertical after delivering a load of parachutists to their

departure altitude. And you should fly the Twin Otter like that. It can do things that almost no other aircraft

can do, so why not do it? Don’t spend too long on knowing your exact Vr speed, the Twin Otter will most

likely start to fly before you reach it. Landing speed is so low that the Twin Otters are regularly landed at far

higher speeds to prevent other aircraft from having to go around behind you.

There is just one thing you always need to keep an eye on. Turbo shaft engines like the PT6A are highly

reliable but the moment you stop thinking about them they go wrong. You will need to keep an eye on the

engine instruments at all time and always use them with respect. They combine low weight with a lot of

power but they are complex and small problems can spiral out of control in an amazing pace.

FLOAT PLANE WITH START LOC KS

The start locks will prevent the floater aircraft moving when the engines are started.

START UP

 Power levers at idle

 Propeller levers full forward

 Starter engage

 Fuel lever On above 12% Ng

Engine will start with start locks engage, thus locks in 0°. This will also be indicated by the Beta range lights

being lit. Increasing the power levers will not produce any forward thrust, thus no or little torque. Since the

start locks keeps the prop pitch at or below 0° You need to move the power into revers range which

actually still is forward thrust 12 -> 0° (Reverse is 0 -> ÷15°)

DISENGAGE THE START LOCKS

 Power levers retard into beta range until torque increases

 Power levers back to idle, Start locks has been disengaged when the beta range lights are unlit.

SHUT DOWN

 Power levers at idle

 Propeller levers full forward

 Fuel levers off

The start locks will engage and the propeller will be in flat pitch, thus 0°

FOR COCKPIT BUILDERS

Our good friend Guenseli has created LINDA/LUA scripts for people who want to use hardware switches

with this aircraft. Not for amateurs but it the results can be amazing. Check it here:
