Ryanair's CEO Suggests Eliminating Co-Pilots
postbigbang writes "Ryanair's miser-in-chief Michael O'Leary now suggests eliminating co-pilots as a way to save money. Will airliners be powered by drones, or is it actually viable to have just a single pilot on passenger planes?"
Yes it can. An autopilot/autothrottle/autoland system can fly an ILS approach, flare and touchdown. It's called CAT III ILS and isn't new technology. It has been around for a few decades. Both JFK and Heathrow have CAT III ILS approaches.
Some people might misunderstand that sentence and interpret that to mean that any autopilot-equipped aircraft is capable of doing this. That is not the case.
First, the avionics aboard many planes in service are not configured from the manufacturer for autoland (e.g. every 737 that American Airlines flies). These can only do "coupled" approaches.
The 737 is delivered from Boeing fully capable of autoland. All modern airplanes these days have at least 2 completely separate autopilots (the 757, 767, and 747-400 have 3 autopilots). However, AA orders their 737s with HUDs (Head Up Display) which are certified by the FAA for the pilot to hand-fly a Cat IIIb approach (700 feet forward visibility, no ceiling). The cost of the HUD quickly pays for itself since the airline does not have to maintain the airplane's autoland certification because the pilots are doing the approaches, not the airplane.
A "coupled" approach simply means that both autopilots are active at the same time, which is normally the case during an autoland; no transport jet's autopilot is certified for a single-autopilot autoland. Coupling the autopilots allows for cross-checking and either fail-passive or fail-operational autoflight. Typically, a two-autopilot airplane like the 737 is certified as fail-passive: a failure of the one autopilot will render the airplane unable to complete the autoland but will not dramatically affect the attitude of the airplane as the pilot takes over. A three-autopilot airplane has both fail-passive and fail-operational characteristics: fail-operational means one autopilot can drop out and the remaining two can still perform the autoland; a second failure is fail-passive and the pilot has to do something.
Second, many smaller planes and older planes are not fully fly-by-wire, so they would require a serious retrofit to make them capable of full autoland.
Fly-by-wire is not a requirement for autoland. Transport-category aircraft have been doing autolands since the 1960s.
If you limit yourself only to fully fly-by-wire planes and limit yourself to major airports, that statement is true. However, the autopilot system in a sizable percentage of aircraft in the air today are NOT capable of autonomous landing.
There are almost no commercial aircraft flying around these days that don't have autoland capabilities. The last of the older generation jet aircraft such as the DC-9 and the 727 are mostly out of major airline passenger service. Any commercial transport jet made after around 1980 has autoland capability by default.
Commercial airlines are already required by law to do a certain percentage of their landings automatically. They just don't tell you...
what you mean is that pilots must remain proficient in Cat 3 and 3a approaches - so they must maintain currency with those procedures by performing one every once in a while. This currency can also be accomplished in a simulator.
Cat 3 and 3a autoland has been around for a long time. (1965)

Trying to do one of these without a co-pilot is ill-advised (1 set eyes on instruments another looking out for the runway environment) - don't forget about radio calls, communication with home base / fuel management / emergencies / etc. I flew very complex, very large planes - and I can tell you that there is a real good reason for at least two in the cockpit. j
